The crankshaft position sensor is a Hall-Effect sensor that senses the crank angle (piston position) of each cylinder and converts it into a pulse signal. The signal from the sensor is relayed to the ECM to indicate engine rpm and the position of the crankshaft.
Removal & Installation
- Disconnect the negative battery cable.
- Disconnect the connector from the sensor.
- Remove the bolt that retains the sensor in place.
- Remove the sensor from its mounting.
- Installation is the reverse of the removal procedure.
- Clearance between the sensor and the sensor wheel should be 0.020-0.059 inch.
- Properly connect the scan tool.
- Start the engine and allow it to idle.
- Be sure the idle position switch is ON.
Specifications are as follows:
Temperature - 4 degrees F, test specification 1500-1700 RPM
