Component Tests and General Diagnostics
CAMSHAFT POSITION (CMP) SENSOR INSPECTIONNOTE: 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)
