Camshaft Position Sensor: Testing and Inspection

CAMSHAFT POSITION (CMP) SENSOR INSPECTION[AJ]

NOTE: Perform the following inspection only when directed.

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




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

Specification: 467-571 ohms




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

Open circuit
- CMP sensor (RH) terminal A and PCM terminal 2AD
- CMP sensor (RH) terminal B and PCM terminal 2AE
- CMP sensor (LH) terminal A and PCM terminal 2AA
- CMP sensor (LH) terminal B and PCM terminal 2AB

Short circuit
- CMP sensor (RH) terminal A and power supply
- CMP sensor (RH) terminal A and body ground
- CMP sensor (RH) terminal B and power supply
- CMP sensor (RH) terminal B and body ground
- CMP sensor (LH) terminal A and power supply
- CMP sensor (LH) terminal A and body ground
- CMP sensor (LH) terminal B and power supply
- CMP sensor (LH) terminal B and body ground
