CRANKSHAFT POSITION (CKP) SENSOR INSPECTION

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 - 325 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 1
- CKP sensor terminal B and PCM terminal 27

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