Map Sensor Reading At Idle In Hg. This indicates the MAP sensor is responding to changes in vacuum. What Should Map Sensor Read At Idle? The speed of idle may vary when the engine is cold and warming up. On an engine with forced induction, the MAP sensor will also measure boost. This vehicle is high at times, indicating pressure pulses in the intake. This is because the MAP sensor measures "absolute" pressure, based on a perfect vacuum, rather than atmospheric pressure. The engine control unit constantly monitors all the sensors in your car engine while you drive the car. A failed MAP sensor has serious implications on fuel control, vehicle tailpipe emissions and fuel economy.
Map Sensor Reading At Idle In Hg. I suspect my MAP is failing. The first test is to make sure the sensor reads atmospheric pressure correctly key on, engine off (KOEO). What Should Map Sensor Read At Idle? This indicates the MAP sensor is responding to changes in vacuum. Just hook up your scan tool and get the MAP reading KOEO. Map Sensor Reading At Idle In Hg.
