Camshaft Position Sensor: Testing and Inspection

CAMSHAFT POSITION (CMP) SENSOR INSPECTION [SKYACTIV-G 2.0]

Intake CMP Sensor

Visual inspection

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. Remove the intake manifold. Service and Repair

5. Disconnect the intake CMP sensor connector.

6. Remove the intake CMP sensor. Service and Repair

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

- If there is a malfunction, 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 intake CMP sensor output voltage using the oscilloscope.

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









*
Output voltage varies with camshaft rotation.

Exhaust CMP Sensor

Visual inspection

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 exhaust CMP sensor connector.

5. Remove the exhaust CMP sensor. Service and Repair

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

- If there is a malfunction, remove any metal shavings that are adhering.
