TEST
3 Measure the voltage on the (K24) CKP Sensor Signal circuit at the CKP Sensor
harness connector.
Is the voltage between 4.5 and 5.0 volts?
Yes → Go To 4
→ Go To 6
No
4 Turn the ignition off.
Disconnect the PCM harness connectors.
Measure the resistance of the (K900) Sensor ground circuit from the CKP Sensor
harness connector to the PCM harness connector.
Is the resistance below 5.0 ohms?
Yes → Go To 5
→ Repair the open in the (K900) Sensor ground circuit.
No
5 NOTE: Inspect the slots on the flywheel for damage. If a problem is found
repair as necessary.
If there are no possible causes remaining, view repair.
Repair
6 Turn the ignition off.
Disconnect the PCM harness connector.
Ignition on, engine not running.
Measure the voltage of the (K24) CKP Sensor Signal circuit at the CKP Sensor
harness connector.
Is the voltage above 5.3 volts?
Yes → Repair the short to voltage in the (K24) CKP Sensor Signal
→ Go To 7
No
7 Turn the ignition off.
Measure the resistance of the (K24) CKP Sensor Signal circuit from the CKP Sensor
harness connector to the PCM harness connector.
Is the resistance below 5.0 ohms?
Yes → Go To 8
→ Repair the open in the (K24) CKP Sensor Signal circuit.
No
8 Measure the resistance between ground and the (K24) CKP Sensor Signal circuit at
the CKP Sensor harness connector.
Is the resistance below 100 ohms?
Yes → Repair the short to ground in the (K24) CKP Sensor Signal circuit.
→ Go To 9
No
