HELP MAP sensor reading 8"hg lower than oilfilled gauge Chevrolet
Map Sensor Reading At Idle In Hg. The reading on my scangauge went from reading close to 13 down to 7.4, not sure whether that's good or not, but definitely feel a significant difference in. Tmauldin discussion starter · jan 4, 2023.
HELP MAP sensor reading 8"hg lower than oilfilled gauge Chevrolet
Tmauldin discussion starter · jan 4, 2023. This is in inches of hg. However, my vacuum gauge reads 14.5hg (which would be about 52 kpa). Web the map sensor (manifold absolute pressure) measures absolute air pressure in the inlet manifold. Web at idle, my map sensor reads 40kpa, which mathematically comes to 18hg. Should a map sensor reading be constant at idle or should it fluctuate. The air pressure in the inlet manifold varies from vacuum to a pressure higher. When throttle is at ~25%, engine load is at ~55% and engine speed is at ~2000 rpm, i can see the map at ~70 kpa. Web the ecu combines the manifold pressure readings from the map sensor with data coming from the iat (intake air temperature), ect (engine coolant temperature) sensor, baro. Web at idle, the map sensor output may be only 100 hertz, whereas, at wide open throttle, it may be as high as 150 hertz.

Web surging poor fuel economy it won't start lack of engine power stalling detonation and misfire however, these symptoms are not exclusively symptoms of a failed map sensor. Web the map sensor (manifold absolute pressure) measures absolute air pressure in the inlet manifold. Symptoms of a faulty map sensor. However, my vacuum gauge reads 14.5hg (which would be about 52 kpa). The gauge uses atmospheric pressure (29.92 at sea level) as. Tmauldin discussion starter · jan 4, 2023.
