Camshaft Position Sensor: Testing and Inspection

1. Disconnect the CMP sensor connector.
2. Measure the resistance between CMP sensor terminals 1 and 2 using an ohmmeter.

Specification
292 - 385 Ohms

- If not as specified, replace the CMP sensor.
- If CMP sensor resistance is okay, but PCM terminals 85 and 86 voltages are out of specification, perform the "Circuit Open/Short Inspection".

Circuit Open/Short Inspection
1. Disconnect the PCM connector.




2. Connect the SST (104 Pin Breakout Box) with the PCM disconnected.
3. Tighten the connector attaching bolt.

Tightening torque
7.9 - 10.7 N.m {80 - 110 kgf.cm, 69.5 - 95.4 in.lbf}

4. Inspect the following wiring harness 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 1 (harness-side) and 104 pin breakout box terminal 85
- CMP sensor terminal 2 (harness-side) and 104 Pin breakout box terminal 86

Short circuit




- If there is continuity, the circuit is shorted. Repair or replace the harness.
- CMP sensor terminal 1 (harness-side) and power supply
- CMP sensor terminal 1 (harness-side) and body ground
- CMP sensor terminal 2 (harness-side) and power supply
- CMP sensor terminal 2 (harness-side) and body ground
