P1190-TIP SENSOR CIRCUIT HIGH —
TEST
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?
Yes → Repair the short to battery voltage in the (A23) TIP Signal circuit.
→ Go To 4
No
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 DRBIII , monitor the TIP Sensor voltage.
Ignition on, engine not running.
Is the voltage below 1.0 volt?
Yes → Replace the TIP Sensor.
→ Go To 5
No
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?
Yes → Go To 6
→ Repair the open in the (K153) TIP Signal circuit.
No
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?
Yes → Go To 7
→ Repair the open in the (K167) Sensor ground circuit.
No
