Hi! I own a Proton Persona Auto year 2008. Can someone kindly show me where are the locations of the MAF and MAP Sensors at the engine. Thanks!

located at the signal indicators there.

thats why very hard to use when switch lane

if use sure kacau GPS navigation.

LEL. thread moved to F&F liao.

I think you can do better than that

No maf sensor

Map sensor usually on intake manifold

I could be wrong tho

i suggest all lowyat.net sections move to /k

Thanks for the reply! Mass air flow sensor (MAF) determines the mass of air entering a vehicle's fuel injection engine, and passes that data to the ECU. So I believes the car has this sensor. When I gave a list of 17 items to Proton Parts Center in Shah Alam, the provide me all the part numbers. Their computer has a grouping for each car model either Auto or Manual.

The MAF sensor part # PW810694
The MAP sensor as the Proton staff calls as the Knock sensor part # PW811757

The Proton staff doesn't allows me to take photograph of the exploded view of the engine diagram so that's why I'm unable to determine the locations of these sensors.

a quick google landed me here



people nowadays, know how to get online and trashtalk, duno how google.
nak kata bodoh nanti terasa tapi nak buat macam mana

when mh370 /k/ got plenty of aviation expert

mau pasang cpu tanya /k/ jugak

beli kereta pun

etc

Many thanks for your efforts bro!

That is actually a Charcoal Fuel Vapor Canister. It is part of the evaporative emission control (EVAP) system in many modern automobiles, which is designed to keep gasoline from evaporating into the atmosphere. Rather than venting a gas tank to the atmosphere, an EVAP system can allow fumes to flow into a canister that contains activated carbon and is therefore capable of absorbing the fuel vapor. This process, coupled with the closed fuel system, can help ensure that a minimal amount of fuel vapor is allowed to reach the atmosphere.

Anyway, I would like to thank everybody who have tried to help me with my question. I will try to ask around in the Internet forums if I can have a better luck. You're doing great guys! Really appreaciate it.

u will get alot of info if u ask about godcar
proton on the other hand...

Lol bro

Knock sensor is knock sensor. It detect engine knocking

Maf sensor for proton only available for wira/satria/putra 1.6, and 1.8. You see, in export market wira is known as persona, so that 'persona' have maf sensor.

Campro use Map sensor i know coz i have campro also
Map sensor is manifold absolute pressure, it send signal to ecu how much air is entering the engine. The name itself is manifold absolute pressure, so it measure pressure in intake manifold. Hence the sensor is located on intake manifold

Most car will only use one map or maf sensor.

Btw snap your engine bay here la, so we can locate

Open the airbox where the filter is, it is usually right next to it.

the campro persona only got map sensor bro. cause i have a persona

Map sensor somewhere on the intake manifold, but so many variations, iafm non iafm, cps

Thanks for your explanation bro! I guess the Proton staff is more confused than myself hehe!

Thanks a lot bro!

Thanks bro! It does help.

Thanks!

Thanks!

I know its an old post but just want to update the location of MAP sensor for Persona 1.6 IAFM as nobody seemed to be able to supply the info.






Dirty vs Clean MAP sensor:




Just use a throttle body spray cleaner to clean the MAP sensor. The degreaser liquid if fast drying. Let the cleaned MAP sensor to dry itself before re-installing.

That's great Bro! Thanks for your info. Really appreciate it! You're a Professional!

what benefit if clean the map sensor? save fuel?

If you can read an accurate reading you can inject the correct fuel right?

What is a map sensor and what does it do?

The MAP sensor converts engine vacuum/manifold pressure to an electrical signal so the computer knows how much load the engine is under. This data is the basis for fuel delivery and timing control.

wow.. thanks. I have learned something new today.

Do use proper cleaner to clean the sensor else will damage the sensitive parts of the sensor

I went to Proton SC to service car, ask them to clean this. They say, if no problem, better don't touch this part, else more headache!

thats cause... as they say, "If it ain't broke, don't fix it"

actually ade 2 reasons.... 1)if anything goes wrong, u cannot blame them 2)working under the assumption all users are idiots, its best users dont touch anything (applies to basically all fields)

biar betik u xtau apatu MAP sensor pffftttt

Just for info sharing.

MAF and MAP are 2 different types of sensors.

MAF measures volume of air entering the engine (usually located at the airbox before the throttle body). MAP measures the Manifold Pressure (usually located past the throttle body).

Either one of the above (with open loop feedback from the O2 sensor and TPS) is used for the ECU to calculate effective fuel delivery.


Most cars now have changed from MAF to MAP sensors since the late 90s.

Shhssssh

They can run either one or both at the same time. Readings are measured all the time regardless of open or close loop from the o2 sensor. Btw, open loop means it's disregarding reading from o2 sensor. Particularly during cold starts or high rpm. Modern cars still uses MAF sensors. They provide accurate volume of air by measuring velocity of air inbound. However if there's leak at the intake interval it causes a huge problem as the measurement is off by a large scale. Map sensors however do not suffer such defects as it's installed at the intake manifold. Any leaks can be detected and ecu can compensate the changes. Downside is the accuracy is not as good as MAF. It relies on atmospheric pressure to estimate the amount of air being suck in. For engines with both system, they are either turbo charged or build for refinement and accuracy. N.A. wise, both MAF and MAP works in tandem to provide accurate volume of air being breath in.

Great discussion!

So where's the thing?

is it the same for persona super value?
