GMC Envoy MAP Sensor is an important sensor that measures positive air pressure which is coming into the intake manifold and sends the information to the ECU for fueling. In the fuel injected engines, the MAP sensor helps in estimating the density of the air and on the optimal mixture of air-fuel that can sustain combustion. Naturally aspirated trims can go with either a MAP or a MAF, but forced induction trims always incorporate both. On-board diagnosis, particularly the function of converting an intake air temperature through MAP sensor, make a very important element in fuel metering and ignition timing for efficient engine performance.
