Camshaft Position Sensor: Testing and Inspection

NOTE: Perform the following test only when directed.

1. Disconnect the CMP sensor connector.




2. Measure the resistance between the CMP sensor connector terminals A and B using an ohmmeter.

Specification: 0.95 - 1.25 kOhm

- If not as specified, replace the CMP sensor.

- If CMP sensor resistance is okay, but PID value or PCM terminal 85 and 86 voltage are out of specification, inspect as follows.
1. Remove the PCM.




2. Connect the SST (104 Pin Breakout Box) to the PCM as shown.
3. Tighten the connector attaching screw.

Tightening torque
7.9 - 10.7 Nm (80 - 110 kg.cm, 69.5 - 95.4 in.lb)

4. Inspect for an open or short circuit in the following wiring harnesses by probing the applicable sensor and SST (104 Pin Breakout Box) terminals with ohmmeter leads.
- If there is an open or short circuit, repair or replace wiring harnesses.
- If there is no open or short circuit, replace the CMP sensor.

Open circuit
- CMP signal circuit (CMP sensor connector terminal A and PCM connector terminal 85)
- CMP signal circuit (CMP sensor connector terminal B and PCM connector terminal 86)

Short circuit
- CMP signal circuit (CMP sensor connector terminal A and PCM connector terminal 85 to Ground)
- CMP signal circuit (CMP sensor connector terminal B and PCM connector terminal 86 to Ground)

3. Reconnect the CMP sensor connector.
