Re: MAP Sensor

I don't get your response. I just got a code referring to the MAF. Was interested in seeing how to change it.

Re: MAP Sensor

The maf is in front of the intake bellows. Unplug its electrical connection and take off the 2 clamps. Might want to properly diagnose 33,34 or 36 if you’re getting any of those codes.

Re: MAP Sensor

MAP - manifold air pressure sensor
MAF - mass air flow sensor

Big difference between the two ...cars that had one did not have the other.... MAF vs speed density systems....
