TEST
10 Turn the ignition off.
Disconnect the CKP Sensor connector.
Ignition on, engine not running.
Measure the voltage on the (K24) CKP Signal circuit.
Wiggle the related wire harness while taking this measurement.
Does the voltage ever increase above 5.5 volts?
Yes → Repair the short to B+ voltage in the (K24) CKP Signal circuit.
→ Go To 11
No
11 Turn the ignition off.
Disconnect the PCM harness connector.
Disconnect the CKP Sensor harness connector.
Measure the resistance between the (K6) 5 Volt Supply circuit and the (K24) CKP
signal circuit at the CKP Sensor harness connector.
Wiggle the related wire harness while taking this measurement.
Is the resistance below 5.0 ohms?
Yes → Repair the short to the (K6) 5 Volt Supply circuit in the (K24) CKP
→ Go To 12
No
12 NOTE: Before continuing, check the PCM harness connector terminals for
corrosion, damage, or terminal push out. Repair as necessary.
If there are no possible causes remaining, review repair.
