Camshaft Position Sensor: Testing and Inspection

CAMSHAFT POSITION (CMP) SENSOR INSPECTION [MZI-3.7]

NOTE:
- Before performing the following inspection, make sure to follow the procedure as indicated in the troubleshooting flowchart. Description and Operation

Visual Inspection

1. Remove the CMP sensor. Service and Repair

2. Verify that there are no metal shavings on the CMP sensor.

3. Install the CMP sensor. Service and Repair

Resistance Inspection

1. Remove the CMP sensor connector.

2. Measure the resistance between the CMP sensor terminals.

- If not within the specification, replace the CMP sensor. Service and Repair
- If the monitor item status/specification (reference) is not within the specification, even though the resistance is within the specification, perform the "Circuit Open/Short Inspection".

CMP sensor resistance
- 800-1,320 ohms

Circuit Open/Short Inspection





1. Disconnect the PCM connector. Service and Repair
