Sensor Information

Crank/Cam Sensor

Waste-spark coilpack variants of this engine use a Crank Position Sensor in the block, and a Cam Position Sensor in the head. Distributor models do not have a cam sensor in the head - however some have the cam position sensor incorporated into the distributor housing.


Crank Sensor

The crank trigger located behind the timing chain drive gear on the crank with the sensor near the alternator. All models have a 36-2 pattern (34 physical teeth; 36 teeth with 2 removed).
