Diagnostic Test

1) ACTIVE DTC
NOTE: Check the TCM for DTCs, if P0706 is set in the TCM diagnose the TCM code before continuing.

Ignition on, engine not running.

While moving the gear selector through all gear positions (Park to 1 and back to Park).

Using a scan tool, select View DTCs.

Is the DTC Active at this time?

Yes
1. Go to 2).
No
1. Refer to INTERMITTENT CONDITION Diagnostic Procedure.
2) TRS (T41) SENSE (P/N SENSE) CIRCUIT OPEN

Turn the ignition off.

Disconnect the C3 PCM harness connector.

Disconnect the Transmission Range Sensor harness connector.

CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install Miller Special Tool #8815 to perform diagnosis.

Measure the resistance of the TRS (T41) Sense (P/N Sense) circuit from the TRS harness connector to the appropriate terminal of special tool #8815.

Is the resistance below 5.0 ohms?

Yes
1. Go to 3).
No
1. Repair the open in the TRS (T41) Sense (P/N Sense) circuit.
2. Perform POWERTRAIN VERIFICATION TEST .
3) TRS (T41) SIGNAL CIRCUIT SHORTED TO GROUND

Measure the resistance between ground and the TRS (T41) Sense (P/N Sense) circuit at the TRS harness connector.

Is the resistance above 100k ohms?

Yes
1. Go to 4).
No
1. Repair the short to ground in the TRS (T41) Sense (P/N Sense) circuit.
2. Perform POWERTRAIN VERIFICATION TEST .
4) TRANSMISSION RANGE SENSOR

Measure the resistance between ground and the (T41) TRS Sense (P/N Sense) circuit while moving the gear selector through each gear in the TRS connector.

NOTE: The circuit is grounded in Park and Neutral and open in the other positions.

Did the resistance change from above 100 kohms (open) to below 10.0 ohms (grounded)?

Yes
1. Go to 5).
No
1. Verify that there is good pin to terminal contact in the TRS and Powertrain Control Module connectors. Replace the Transmission Range Sensor.
2. Perform POWERTRAIN VERIFICATION TEST .
5) POWERTRAIN CONTROL MODULE (PCM)
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Transmission Range Sensor and the Powertrain Control Module (PCM).

Look for any chafed, pierced, pinched, or partially broken wires.

Look for broken, bent, pushed out or corroded terminals. Verify that there is good pin to terminal contact in the TRS and Powertrain Control Module connectors.

Refer to any Technical Service Bulletins that may apply.

Were there any problems found?

Yes
1. Repair as necessary.
2. Perform POWERTRAIN VERIFICATION TEST .
No
1. Replace and program the Powertrain Control Module per Service Information.
2. Perform POWERTRAIN VERIFICATION TEST .
