Crankshaft Position Sensor: Testing and Inspection

CRANKSHAFT POSITION (CKP) SENSOR INSPECTION[AJ]

NOTE: Perform the following inspection only when directed.

Resistance Inspection
1. Disconnect the negative battery cable.
2. Disconnect the CKP sensor connector.




3. Measure the resistance between CKP sensor terminals A and B using an ohmmeter.
- If the CKP sensor is okay, but the PID value is out of specification, perform the "Circuit Open/Short Inspection".
- If not as specified, replace the CKP sensor.

Specification :267-25 ohms




Circuit Open/short Inspection
1. Disconnect the PCM connector.
2. Inspect the following harness for open or short circuit. (Continuity check)

Open circuit
- CKP sensor terminal A and PCM terminal 2Z
- CKP sensor terminal B and PCM terminal 2Y

Short circuit
- CKP sensor terminal A and power supply
- CKP sensor terminal A and body ground
- CKP sensor terminal B and power supply
- CKP sensor terminal B and body ground
