TEST
3 Turn the ignition off.
Disconnect the TIP Sensor harness connector.
Ignition on, engine not running.
With the DRBIII , monitor the TIP Sensor voltage.
Is the voltage between 4.5 and 5.2 volts?
Yes → Replace the TIP Sensor.
→ Go To 4
No
4 Turn the ignition off.
Disconnect the TIP Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between the (A23) TIP Sensor signal circuit at the TIP Sensor
harness connector and ground.
Is the resistance below 100 ohms?
Yes → Repair the short to ground in the (A23) TIP Sensor signal circuit.
→ Go To 5
No
5 Turn the ignition off.
Disconnect the TIP Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between the (A23) TIP Sensor signal circuit and the (K167)
Sensor ground circuit in the TIP Sensor harness connector.
Is the resistance below 100 ohms?
Yes → Repair the (A23) TIP Sensor signal circuit for a short to the
→ Go To 9
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 (K6) 5 Volt Supply circuit from the TIP Sensor harness
connector to the appropriate terminal of special tool #8815.
Is the resistance below 100 ohms?
Yes → Go To 7
→ Repair the open (K6) 5 Volt Supply circuit.
No
