Crankshaft Position Sensor: Testing and Inspection
CRANKSHAFT POSITION (CKP) SENSOR INSPECTIONNOTE: Perform the following inspection only when directed.
Resistance Inspection
1. Disconnect the negative battery cable.
2. Disconnect the CKP sensor connector.
3. Measure the resistance between the CKP sensor terminals A and B using an ohmmeter.
- If the CKP sensor is okay, but the PID value is out of specification, perform the "Circuit Open/Short Inspection".
- If not as specified, replace the CKP sensor.
Specification: 315 - 385 ohms
Circuit Open/Short Inspection
1. Disconnect the PCM connector.
2. Inspect the following harness for open or short circuit. (Continuity check)
Open circuit
- CKP sensor terminal A (harness-side) and PCM terminal 22 (harness-side)
- CKP sensor terminal B (harness-side) and PCM terminal 21 (harness-side)
Short circuit
- CKP sensor terminal A (harness-side) and power supply
- CKP sensor terminal A (harness-side) and body GND
- CKP sensor terminal B (harness-side) and power supply
- CKP sensor terminal B (harness-side) and body GND
