RATE
Description
1 . The engine control module (ECM) provides a 5V power source to the intake
manifold pressure sensor through the sensor power circuit.The ECM also
provides a grounding to the sensor circuit.The intake manifold pressure sensor
through its signal circuit provides a signal to the two ECM.The signal voltage
of the sensor will varies depending on the intake manifold pressure. ECM
monitors turbocharger performance via manifold pressure readings.
