CRANKSHAFT POSITION (CKP) SENSOR INSPECTION [AJ]

Resistance Inspection

1. Disconnect the CKP sensor connector.
2. Measure the resistance between CKP sensor terminals A and B using an ohmmeter.
- If not as specified, replace the CKP sensor.
- If CKP sensor resistance is okay, but PID value or PCM terminals 1 and 27 voltages are out of specification, perform the "Circuit Open/Short Inspection".

Specification: 267 - 325 ohms

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: 3.0-5.4 N.m {30-56 kgf.cm, 27-48 in.lbf}




4. Inspect the following wiring harness for open or short circuit (Continuity check).

Open circuit
- If there is no continuity, the circuit is open. Repair or replace the harness.
- CKP sensor terminal A (harness-side) and 104 pin breakout box terminal 27
- CKP sensor terminal B (harness-side) and 104 pin breakout box terminal 1

Short circuit
- If there is continuity, the circuit is shorted. Repair or replace the harness.
- CKP sensor terminal A (harness-side) and power supply
- CKP sensor terminal A (harness-side) and body ground
- CKP sensor terminal B (harness-side) and power supply
- CKP sensor terminal B (harness-side) and body ground
