Camshaft Position Sensor: Testing and Inspection

CAMSHAFT POSITION (CMP) SENSOR INSPECTION [MZR 2.0, MZR 2.5]

Visual Inspection

CAUTION:
- When replacing the CMP sensor, make sure there is no foreign material on it such as metal shavings. If it is installed with foreign material, the sensor output signal will malfunction resulting from fluctuation in magnetic flux and cause a deterioration in engine control.

1. Remove the battery cover. Removal and Replacement

2. Disconnect the negative battery cable. Removal and Replacement

3. Remove the plug hole plate. Plug Hole Plate Removal/Installation

4. Disconnect the CMP sensor connector.

5. Remove the CMP sensor. Service and Repair

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

- Remove any metal shavings that are adhering.

Voltage Inspection

CAUTION:
- When replacing the CMP sensor, make sure there is no foreign material on it such as metal shavings. If it is installed with foreign material, the sensor output signal will malfunction resulting from fluctuation in magnetic flux and cause a deterioration in engine control.
- If the wiring harnesses or waterproof connectors are damaged, water penetrating the connector will cause a sensor malfunction. To prevent this, be careful not to damage wiring harnesses or waterproof connectors.

1. Idle the engine.

2. Measure the CMP signal and verify that rectangular waves are produced. Component Tests and General Diagnostics

- If not as specified, replace the CMP sensor. Service and Repair
