CAMSHAFT POSITION (CMP) SENSOR INSPECTION [L3]

NOTE: Before performing the following inspection, make sure to follow the troubleshooting flowchart.

Resistance Inspection




1. Disconnect the CMP sensor connector.
2. Measure the resistance between CMP sensor connector terminals A and B.
- 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", and repair or replace the malfunctioning part.

Resistance: 400-550 Ohms

Circuit Open/Short Inspection




1. Disconnect the PCM connector.
2. Inspect the following wiring harnesses for an open or short circuit. (Continuity inspection)

Open circuit

- If there is no continuity, there is an open circuit. Repair or replace the wiring harness.
- CMP sensor terminal A and PCM terminal 2V
- CMP sensor terminal B and PCM terminal 2U

Short circuit

- If there is continuity, there is a short circuit. Repair or replace the wiring harness.
- CMP sensor terminal A and power supply
- CMP sensor terminal A and body ground
- CMP sensor terminal B and power supply
- CMP sensor terminal B and body ground
