Vertical Acceleration Sensor: Description and Operation

ACCELEROMETER

The Piezoelectric Accelerometer is used to detect unevenness in the road surface which is transferred to the engine via the sub-frame. When
unevenness exceeds a certain level the misfire diagnostic is switched OFF.

The accelerometer receives 5 V from the Engine Control Module (ECM). Its output signal is approx. 2.5 V for a stationary car. When there is vertical
movement the signal will oscillate around 2.5 V.

The Accelerometer is mounted on the sub-frame.
