How does the ECM use the MAF sensor?
How does the ECM use the MAF sensor? The ECM utilises the MAF sensor output signal to precisely schedule fuel injection, creating an optimal air-fuel ratio. This results in reduced emissions and improved fuel economy, all while maintaining drivability. Where is the output wire on a mass air flow sensor? The circuit is a simple attenuator made by only two resistors. The output wire of the MAF is cut and the circuit is placed between the MAF and the ECU. According to my information the MAF signal wire is brown/blue. (your colors may be different) It is pin number 5...
