TEST ACTION APPLICABILITY
3 Turn the ignition off.
Disconnect the TIP Sensor harness connector.
Ignition on, engine not running.
Measure the voltage of the (K153) TIP Signal circuit in the TIP Sensor harness
connector.
Is the voltage above 5.2 volts?
All
Yes → Repair the short to battery voltage in the (A23) TIP Signal circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
No → Go To 4
4 Turn the ignition off.
Disconnect the TIP Sensor harness connector.
Connect a jumper wire between the (A23) TIP Sensor Signal circuit and the (K167)
Sensor ground circuit.
With the DRBIIIt, monitor the TIP Sensor voltage.
Ignition on, engine not running.
Is the voltage below 1.0 volt?
All
Yes → Replace the TIP Sensor.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
No → Go To 5
5 Turn the ignition off.
Disconnect the TIP 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 (K153) TIP Signal circuit from the TIP Sensor harness
connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
All
Yes → Go To 6
No → Repair the open in the (K153) TIP Signal circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
6 Turn the ignition off.
Disconnect the TIP 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 (K167) Sensor ground circuit from the TIP 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 (K167) Sensor ground circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
