sometimes i dont press the fuel paddle aso the rpm so high until 3 to 4 and sometimes to 5 rpm

it so hard to drive when it jammed
actually this problem is found first i bought the car
but the servis centre say is the spec for gen2

it supposed to be like that for Campro. I still remember the 1st time I drive Campro (it was a Gen-2), I also think something was wrong coz I drive wira daily. BUt if the RPM spike even if you are stationary and did not press the throttle, there could be something wrong. TB's ISC maybe?

Auto or Manual?

I'm using auto Gen-2 , year 2004 spec.
I cant say much bout manual, but from what I know based on auto gearbox concept:

When I was rev-ing high (above 4k rpm, which is typical if I'm overtaking in highway, or "flying" down a slope ;do remember that gen2's auto has auto-shift down concept) I will get the following scenario:

When I start to slow down or stop (traffic light, toll booths), my RPM will remain high, and it will then slowly drop.

This is because somehow (not familiar with the concept), the engine will "cool itself down" and "refuse" to drop the RPM directly. Maybe it is controlled by ECU or maybe it is the auto gearbox

But it normally happen after a high rev, not while I am stationary or <3k constant RPM .

by the way
wat is TB's ISC ?
dont understand


sometimes when i in slow drive
i change gear without press my fuel paddle

This is the weirdest problem I read here.Could it be your clutch plate is slipping.Its abnormal if you ask me.

try going on a slope and then accelerate on the gear and then go on neutral,and see if your RPM still climb.If it does,your clutch is slipping.Another problem should be a faulty Throttle body.Replacing one with Proton SC will set you back more than RM700++ ori parts

all this is because of the "smart" ECU used in Gen2 by the proton guys, it actually provide a safety cut so that when u are not pedalling, the car speed goes up , it means you are downhill... so it will down step one gear ...

so for all gen2 driver... try this and u will learn how to cheat the ECU...
when you are going down hill... don let go the pedal all the way.. just slowly release the pedal let the ecu read that you are actually decreasing speed instead....

it work .... believe me ... even for persona too...

That is downshifting ... and to be exact, cheating downshift ECU calculations

If you read TS's post, it is more toward upshifting (high RPM when driver shift up , 1-to-2, or 2-to-3)

Actually, it could have been caused by ECU ... Campro is an high-rev engine, so I wont be surprise if the ECU rev the engine to maintains the powerband when driver manually shift-up (when there is not enough power during shifting)

Cant help very much as I'm on auto mode . zzz

bro, u mean when u depress clutch and release throttle during manual shift up, rpm does not drop??... ur rpm stays at what rpm during the period u let go ur throttle??....

so far as i conclude is dat... connection between speed sensor, throttle position and ecu.... could be faulty speed sensor, sending wrong signal to ecu, causing it to blimp up the throttle....

jz a suggestion... coz i wouldnt be normal if the rpm does not drop even ur throttle is off...

One possible alternative is to send to PSC.

Ask them to plug the reader to ECU, then take a test drive.

If the RPM climbs instead during changing of gear, ECU might be able to show some insights to the fuel-air-mixture, O2 reading etc ..

true enuff like the sc told u its 'the spec for campro' laugh.gif

anyway its not actually the spec, its the drive by wire where ur throttle response is being read electronically...

even u have release the paddle, the throttle will take some short time before the timing goes down to normal...

for early batch of gen2 where u got the old powerful 2004 ecu, this problem is common...sometime the idling will stay at around 1.5k n only goes down after a while...what i normally do when i drove a car with this ecu, i just lift the paddle up n off ur engine leave it a bit n start...if the rpm still shoot up high, u have to do it again...

anyway if u hate that characteristic that much come swap with my ecu...2004 ecu is well known for its powerful mapping where it provides higher sparks...

another way to confirm is go to sc, have them checked ur ecu version n if it is a 2004 batch, ask them to flash the ecu to latest mapping...BUT u'll lose the pickup provided by the old mapping...well u win some lose some right...

i have done tons of thing to my gen2 but i can't kick it up to 200 at least when i ram the car the best it will go to 180 then drops back to 170
damn tention... change the crank pulley change the manifold but still no power when i first got the car it had no problems then after 2 year it's start having problems with the speed . do i have to change my ecu or should i try snorkeling or arghhhh running out of ideas hELP ASAP??? rclxub.gif rclxub.gif cry.gif :cry

Yep, the throttle for the new Campro engine is now drive-by-wire.. It is a known 'phenomema' for the new Gen2/Persona cars which have this throttle blip when you press on the clutch during gear shift.. It's all programmed in the ECU.. Have no idea why they introduce this characteristic in the ECU (a software glitch maybe?) but it sure is annoying for manual driving..

all campro engine is drive-by-wire... including the 1st generation campro...

not sure about the throttle blip though.. how much it increases ur engine revs when u step on the clutch??... safety feature for noob drivers to prevent engine stall??... unsure.gif

Although its DBW characteristic to have some lag between pressing and de-pressing the throttle pedal, rpm jumping to 5k is really not normal. Maybe the throttle position sensor got problem (too tight and made it a little stuck).

since your rpm is usually high, how is the fuel consumption?

at what speed you normally shift up from 1st to 2nd gear and from 2nd to 3th?

I didnt know the technical terms for cars and engine, but I'll tell you guys briefly what happened to my husband's gen2 last Friday which was very horrifying. (The Gen2 is 5 years old, mileage 120K+).

A few months ago, the engine check warning light triggered and when that happened, the car kept on jerking while driving. We called Proton i.care and they said it is still safe to drive and we must send the car to the service centre immediately. And so we did. Proton Service centre A said, it has got to do with the wiring in the electronic system. The system is very sensitive and we must've bummed into something or the system masuk air. So they reset the system. If the problem occurs, we must send the car for a thorough check-up.

A few weeks after that, it happened again and this time, the car suddenly stopped. Luckily we managed to pull over on time at the emergency lane . We tried to start the engine, but it wont start. So we leave it a few minutes, and tried again. Luckily, the engine started but the engine check warning light triggered again. However this time, there was no jerking while driving.

So we sent the car to a bigger Proton Service Centre (B). Hoping that they'll figure up the problem since that was the 2nd time it occurred. The technical people at B said exactly what people at A told us, it's the wiring system but this time, they said the acceleration pedal has worn out. Need to change a new one.

Happy as a bird, we drove the car worried-free. Sent the car for a major service last month. Until last Friday, the car suddenly stopped at the fast lane of a 4-lane Jalan Istana at 11.30pm!!! With the remaining momentum, the car managed to move a bit to the 3rd lane (another lane to go). Unfortunate for us, it wont start at all this time. At that very risky and dangerous situation, we waited for the car to be towed.

We called Proton the next morning and told them what happened since that was the 3rd time. And yes, we said dont tell us it's the wiring thing again. Well, they had no clue and asked us to send the car to any Proton Service Centre and had to leave the car there.

However, we called this freelance mechanic (D) which we have known for almost 10 years. I dont know the terms but he told us, api tak sampai when he tried to start the car plus the rpm went to the max. He checked the sensor and told us 2 sensors have worn-out. (Dont know which one was he referring to). So he changed it. So far (it's only been 2 days), the car has no problem (we drove from KL to Putrajaya last night, still feeling traumatise of what happened, so we stayed at the left lane all the way.)

Anyway, D told us, the sensors should have been changed because the car is already 5 years old and the Proton people should have known about this. For a 5-year old car, the sensors are the 1st thing they should checked when check engine warning light triggered. And he added, this problem is also quite common for Lancer cars.

Our question is, is it true they (the Proton people) are willing to know that it is the sensor problem when the check engine warning light triggered? Because if it's true then I would like to send a complaint letter to Proton for a lousy service and jeopardizing our lives.

No idea what that is hmm.gif

Well anyway, I did some digging on the internet until I came accross this website

http://www.bcaa.com/wps/portal/BCAA/cars/c...hs.xsl/1629.htm

and this website http://www.aa1car.com/library/mil.htm

which I found quite informative.


It's stated there that the faulty codes wont be abled to determine which part to replace (or whatever) and further diagnosis need to be done.

I guess, B didnt do a further diagnosis even though we have told them the problem occured the 2nd time after A reset the system to set off the check engine light and B just reset the whole thing again as jalan mudah. vmad.gif

the worker at proton service centre sometimes not that knowledgeable or has experience..sometimes just they are just guessing and u get a stupid solution

yes, reset the ecu will remove the error codes, and no more check engine light, but it wont solve the real problem

the worker at proton service centre sometimes not that knowledgeable or has experience..sometimes just they are just guessing and u get a stupid solution

yes, reset the ecu will remove the error codes, and no more check engine light, but it wont solve the real problem

guess its time to send your car for through check.

Send to proton .Ask them to plug in the reader and find the error code.
Then from the error code, they would know what the problem is. You can also request for the error code meaning from them and repair outside.
Not many outside shop have the ECU reader and thus, wont be able to help. Normally they would use the "trial-and-error" style.

Who reset the ECU for your car? proton side or outside shop? If outside shop, good luck. If Proton, you can go back and get the report of the previous service (error code).

Oh yeah... forgot bout that method..

The thing I wanted to inform is that by reset-ing ECU, the error code and log is deleted. Thus, it become harder to find the root cause of the problem.

When engine light is lit, means one of the sensor is reporting abnormality and the ECU is telling you something is wrong. There are hundreds of error code, how to guess?

You don't go and reset the ECU (That is the worst thing you can do). If reset already and the error still come up, it should clue you in that the problem is not solved.

You should send it to Proton or any workshop that have the equipment to read your ECU to find out what is wrong.

Hi...
This is your lucky day.
My wife's Gen 2 1.3 have exactly the same problem for long time. Need to switch off engine for a while and the warning light may go off right?
Feel damn stupid driving a car like that as I used Saab for over a decade. Still using one.
I've sent the Gen 2 to Proton service center in Sec 13 PJ. They checked, said EMS error code PO120. They said that means can be due to
1)wiring problem, or 2) Pedal sensor, or 3) Throttle Body.
Went thro the process of elimination, first 2 were eliminated. That took 3 trips.
Sent in again today after they ordered parts (which took weeks), they said with new throttle body seems to work OK.
I'll be picking up the car tomorrow so that can test over the weekend. Part alone >RM500. Labour cost don't know yet.
Frankly, I will only get to know if it's really solved in a week's time after some road tests. Keep my fingers crossed.

The car can be dangerous to drive with the previous condition as there is no power at all when you needed it, like going on a slope.
Think it is this a design problem.

Call this guy Azhar 019 3752410. Helpful fellow.
See if u can short cut the trial and error and focus on the throttle body right away.

Good Luck.

Hi,
I guess it outdated post, but very informative.

I just did major services with timing belt, water pump, tensioner changed to my gen2 manual.
The problem now is when release the clutch, the engine RPM will suddenly drop to 200-300 rpm. Can hear the engine will low rpm and going to shut off (50-60% when slow down car to stop, and pressing the clutch will get this).

The horrible thing is, there is few times the campro engine shut off and engine light on, when I press the clutch. I need to quickly switch the key to off, and turn ignition on to start back the engine. And imagine the challenge when this happen on the road... smile.gif

Do you guys have any idea, before I go back to the mechanic? I use outside mechanic to change all those stuff.

I will try the remove battery wire method to reset ECU and see how thing go on.

Go to Proton SC, let them plug in device to check the code. Clear the ECU fault code wont solve the problem
Most likely your o2 sensor kong, but anyway just go to Proton sc to let them diagnose

Try to clean your IACV (Idle Air Control Valve).. Usually thats the thing that causes idle to drop below the intended rpm.

More test result.

Car left idling without a/c turn on - no problem, work good and no low rpm, stay at 900++ rpm.
Car left idling, turn on a/c - no problem, when a/c compressor on, the rpm stay at 950 - 1000 rpm. After a/c disengage, it remain 900++ rpm.

Drive at 30-50 km/h cruising, without pressing break, press the clutch, and rpm dip to 200-300 rpm and bounce back 900+. Tested 10 times and will get engine "mati" once.... Almost every time the same scenario (around cruising speed and press clutch) engine will low to 200-300 rpm and bounce back to 900+ rpm. Intermittently will hear engine like want to mati due to low rpm. Once awhile will get the real engine mati. Need quickly switch key to off, and turn on ignition to get engine alive.

Will ask the same mechanic whether could tune the idling rpm higher? If there is no any tuning for campro, then need send to Proton SC.

The car loan got settle. And it a less than 10 years first hand gen2.
since it working good, no plan to change. I rather spend 2-3k repair per year than buy new car for RM65k++ (example: Preve) and possible to get unknown headache issue. The problem I facing now also due to major services (timing belt, tensioner, water pump, 4-to-1 ekzos to remove catalytic converter). Once I manage to fix this issue, I think it will serve me well again. smile.gif

Even to get a new car, proton will not in the list. Sorry to proton fan. I know the car is okay and value for money, but the overall perception, I will go for non-proton. Just my personal preference, after I experience first own proton's car (do not count car from parents, friend... bla bla, this truly I drive it everyday)

By the way, my gen2 serve me good for 10 years, with unavoidable problem/issues (steering clock spring, door handle broken, power-windows fixture, aircon compressor jam, bad low rpm torque and kena engine mati at traffic light, ekzos tailpipe rusted), at least it meet my min requirement - no break-down on road.

Wow very good car, 10 years with that car yet never give you breakdown on the rood. And that is Gen 2 first car release from Proton built in house. You can imagine what Preve will be good for you.

Did you change your exhaust header at the same time as u do major service(timing belt etc)
Yup maybe it had to do with your ECU..check with proton sc or you also can try at some workshop which they have the PDT(proton diagnosis tools)

Yes, do all in one go.
Had try unplug battery cable to reset the ECU, now observe how it going... at the moment look good, if till weekend and never happen again, then problem should be consider resolve. If not, then need go visit SC.

maybe your ecu is on "relearning" process
i not quite sure about gen2 ECU...maybe it use 16 bit...same as my BLM
so "relearning" will take some time...

p/s:
i also face the same problem like you when i did change my timing belt..
mine is worst because auto..detect it early and not far from the workshop...
so the workshop did a PDT test...no error code...
take out battery terminal also didn't solve it...
so they try taking out the TB(throttle body) and clean it...

Hi budakdegilz,
You are right. I went to proton service center. The tech just drove my car, then he take out spark-plug and remove the throttle body to wash. From him, it very common issue for campro engine. After high mileage, sure will kena throttle related problem, all sort of weird behavior like mati engine while cornering and etc.

After washing throttle body, change spark plug, and pluged in device - relearning throttle body setting, reinit bla bla.... low timing issue resolved.

Now, the campro engine like *new* engine, where when release clutch, it will rev the rpm higher for some time..... good thing is no mati engine problem, bad thing, quite hard to drive and need use to it again..

maybe your ecu is on "relearning" process
i not quite sure about gen2 ECU...maybe it use 16 bit...same as my BLM
so "relearning" will take some time...

p/s:
i also face the same problem like you when i did change my timing belt..
