I wanna know if I dont replace it, long term will have major problem or not? Any owner that experience IAFM module problem but never replace it? pls share share
last time i had a chat with Proton mechanic in Glenmarie,they say the tak tak tak sound may came from 2 sources.I wanna know if I dont replace it, long term will have major problem or not? Any owner that experience IAFM module problem but never replace it? pls share share
The IAFM and purge valve canister.
For me ,i will just replace the purge valve canister first.if your FC seem worrying from time to time.Change this.Much more cheaper and easy to replace.
CODE
A canister purge valve is a solenoid valve controlled by the Power Train Control Module. The Power Train Control Module is a control unit that determines the ignition timing, fuel amounts and other parameters needed to keep the engine running.
Function
The canister purge valve serves as part of the emission control system in a car, and it measures the flow and amount of fuel vapor that is recycled into the combustion process via the charcoal canister, or fuel vapor storage device. Canister purge valves are also used in "leak tests," by allowing a vacuum to be created throughout the fuel storage system when the valve is closed, thus preventing outside air from entering the system.
Performance
Factors that can affect the performance of a canister purge valve include unclean valve conditions and valve blockage. Valve blockage is caused when an obstruction becomes lodged in the opening of the valve, causing a backup of the fuel and air mixture.
