TEST ACTION APPLICABILITY
3 Turn the ignition off.
Disconnect the Knock Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between ground and the (K42) KS Signalcircuit at the Knock
Sensor harness connector.
Is the resistance below 100 ohms?
All
Yes → Repair the short to ground in the (K42) KS Signal circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
No → Go To 4
4 Turn the ignition off.
Disconnect the Knock 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 (K42) KS Signal circuit fromthe Knock Sensor harness
connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
All
Yes → Go To 5
No → Repair the open in the (K42) KS Signal circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
5 Turn the ignition off.
Disconnect the Knock Sensor harness connector.
Measure the resistancebetween the (K42) KSSignal circuit and the (K45)KS Return
circuit in the Knock Sensor harness connector.
Is the resistance below 100 ohms?
All
Yes → Repair the (K42) KS Signal circuit for a short to (K45) KS Return
circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
No → Go To 6
6 Turn the ignition off.
Disconnect the Knock 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 (K45) KS Return circuit from the Knock Sensor
harness connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
All
Yes → Go To 7
No → Repair the open in the (K45) KS Return circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
