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. (See HOW TO
USE THIS MANUAL.)
Visual Inspection
1. Remove the CMP sensor.
2. Verify that there are no metal shavings on the CMP sensor.
3. Install the CMP sensor.
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.
-
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.
2.Inspect the following harness for open or short circuit. (Continuity check)
