P0335-CRANKSHAFT POSITION SENSOR CIRCUIT —
TEST
10 Turn the ignition off.
Disconnect the CKP Sensor harness connector.
Ignition on, engine not running.
Measure the voltage of the (K24) CKP Signal circuit in the CKP Sensor harness
connector.
Is the voltage above 5.5 volts?
Yes → Repair the short to battery voltage in the (K24) CKP Signal
→ Go To 11
No
11 Turn the ignition off.
Disconnect the CKP Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between the (K24) CKP Signal circuit and the (K6) 5 Volt
Supply circuit in the CKP Sensor harness connector.
Is the resistance below 5.0 ohms?
Yes → Repair the (K24) CKP Signal circuit shorted to the (K6) 5 Volt
→ 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, view repair.
Repair
13 Turn the ignition off.
Disconnect the CKP Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between ground and the (K6) 5 Volt Supply circuit in the CKP
Sensor harness connector.
Is the resistance below 100 ohms?
Yes → Repair the short to ground in the (K6) 5 Volt Supply circuit.
→ Go To 14
No
14 Turn the ignition off.
Disconnect the CKP Sensor harness connector.
Disconnect the PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure the resistance of the (K6) 5 Volt Supply circuit from the CKP Sensor harness
connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
Yes → Go To 15
→ Repair the open in the (K6) 5 Volt Supply circuit.
No
