Gm mass air flow sensor wiring - a mass air flow sensor maf is a sensor used to determine the mass flow rate of air entering a fuel injected internal bustion engine the air mass information is necessary for the engine control unit ecu to balance and deliver the correct fuel mass to the engine often the mass air flow sensor readings are measured at idle 1 000 rpm 2 000 rpm and 3 000 rpm a contaminated or bad air flow sensor will in most cases show lower air flow the mass airflow sensor maf measures the amount of air entering the engine the obd ii code p0101 is set when the signal from the mass air flow sensor is out of expected range or in other words the maf sensor doesn t work properly hello my name is john the mass air flow sensor is in the accordian looking tube that runs from the air filter housing to the engine it is near the end closest to the air filter housing 5 wires e out of the side of the sensor i cleaned my.
maf sensor today and when i was taking off the wiring connector i broke the stupid little white clip that holds the connector on p0101 gm type powertrain fuel and air metering iso sae controlled description maf sensor performance conditions cause no maf or tp sensor codes set system voltage over 11v engine running then the pcm did not detect any maf input for 2 seconds inspect the maf sensor wiring and connectors for damage p0102 gm type powertrain fuel and air metering iso sae controlled description maf sensor circuit low frequency conditions cause engine runtime over 2 seconds engine speed more than 300 rpm system voltage more than 10v throttle position less than 50 then the pcm detected that the maf sensor input was 10 hertz or less less than a vehicle s mass airflow sensor or maf is the ponent that measures the flow and density of the air flowing into the bustion chamber gm has issued.
