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!

I think you can do better than that

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

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.

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.

Great discussion!
