CAMSHAFT POSITION (CMP) SENSOR INSPECTION [LF, L3]

Note

• Before performing the following inspection, make sure to follow the procedure as indicated in the troubleshooting flowchart. (See Troubleshooting Procedure.)

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. (See PCM REMOVAL/INSTALLATION [LF, L3].)

2. Inspect the following wiring harnesses for open or short. (Continuity check)

Open circuit

• If there is no continuity, the circuit is open. Repair or replace the harness.

- CMP sensor terminal A and PCM terminal 2V

- CMP sensor terminal B and PCM terminal 2U

Short circuit

• If there is continuity, the circuit is shorted. Repair or replace the harness.

- CMP sensor terminal A and power supply

- CMP sensor terminal A and body GND

- CMP sensor terminal B and power supply

- CMP sensor terminal B and body GND
