Diagnostic Test
- CHECK FOR AN ACTIVE DTC
- Turn the ignition on.
- With the scan tool, read DTCs and record on the repair order.
Is the DTC active or pending?
Yes
- Go To 2
No
- Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION .
- CHECK FOR OTHER DTCS
- Refer to the recorded DTCs.
Are there any 5-Volt Reference DTCs active or pending?
Yes
- Perform the applicable diagnostic procedure(s). Refer to DTC INDEX (1 OF 2) and/or DTC INDEX (2 OF 2) .
No
- Go To 3
- Refer to the recorded DTCs.
- CHECK THE CLUTCH POSITION SENSOR (T119) POSITION SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE
- Turn the ignition off.
- Disconnect the Clutch Position Sensor harness connector.
- Turn the ignition on.
- Measure the voltage on the Clutch Position Sensor (T119) Position Signal circuit at the Clutch Position Sensor harness connector.
Is the voltage reading above 5.2 volts?
Yes
- Repair the Clutch Position Sensor (T119) Position Signal circuit for a short to voltage.
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
No
- Go To 4
- CHECK FOR THE CLUTCH POSITION SENSOR (T119) POSITION SIGNAL CIRCUIT SHORTED TO THE (K859) 5-VOLT SUPPLY CIRCUIT
- Turn the ignition off.
- Disconnect the PCM C1 harness connector.
- Check for continuity between the Clutch Position Sensor (T119) Position Signal circuit and the (K859) 5-Volt Supply circuit at the Clutch Position Sensor harness connector.
Is there continuity between the Clutch Position Sensor (T119) Position Signal circuit and the (K859) 5-Volt Supply circuit?
Yes
- Repair the short between the Clutch Position Sensor (T119) Position Signal circuit and the (K859) 5-Volt Supply circuit.
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
No
- Go To 5
- CHECK THE ABILITY OF THE PCM TO READ THE CLUTCH POSITION SENSOR SIGNAL
- Turn the ignition off.
- Reconnect the PCM C1 harness connector.
- Connect a jumper between the Clutch Position Sensor (T119) Position Signal circuit and the (K917) Sensor Ground circuit at the Clutch Position Sensor harness connector.
- Turn the ignition on.
- With the scan tool, read DTCs.NOTE:
The scan tool should display the P0807-CLUTCH POSITION SENSOR CIRCUIT LOW DTC as active or pending with the jumper in place.
Does the scan tool display as described above?
Yes
- Replace the Clutch Position Sensor in accordance with the Service Information. The CLUTCH PEDAL POSITION SENSOR LEARN routine must be performed every time there has been a repair/replacement made to a Clutch Position Sensor, PCM or Clutch Pedal Assembly. Failure to do so can cause the Clutch Position Not Learned DTC to set. With a scan tool, perform the CLUTCH PEDAL POSITION SENSOR LEARN routine.
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
No
- Go To 6
- CHECK RELATED HARNESS CONNECTIONS
- Disconnect all PCM harness connectors.
- Disconnect all related in-line harness connections (if equipped).
- Disconnect the related component harness connectors.
- Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
- Proper connector installation.
- Damaged connector locks.
- Corrosion.
- Other signs of water intrusion.
- Weather seal damage (if equipped).
- Bent terminals.
- Overheating due to a poor connection (terminal may be discolored due to excessive current draw).
- Terminals that have been pushed back into the connector cavity.
- Check for spread terminals and verify proper terminal tension.
Repair any conditions that are found.
- Connect all PCM harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
- Connect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
- Connect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
- With the scan tool, erase DTCs.
- Test drive or operate the vehicle in accordance with the when monitored and set conditions.
- With the scan tool, read DTCs.
Did the DTC return?
Yes
- Replace and program the Powertrain Control Module (PCM) in accordance with the Service Information. Refer to MODULE, POWERTRAIN CONTROL (PCM), REMOVAL AND INSTALLATION .
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
No
- The wiring or poor connection problem has been repaired.
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
