Crankshaft Position Sensor: Testing and 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 RPM PID value or PCM terminals 21 and 22 voltages are out of specification, perform the "Circuit Open/Short Inspection".

Specification
315 - 385 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
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.
- CKP sensor terminal A (harness-side) and 104 pin breakout box terminal 21
- CKP sensor terminal B (harness-side) and 104 pin breakout box terminal 22

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
