Component Tests and General Diagnostics
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 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
267 - 325 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 and PCM terminal 1
- CKP sensor terminal B and PCM terminal 27
Short circuit
- CKP sensor terminal A and power supply
- CKP sensor terminal A and body GND
- CKP sensor terminal B and power supply
- CKP sensor terminal B and body GND
