Diagnostic Routine D

Diagnostic Overview

P0705, P0706, P0708, P0709, P1702, P1705

Refer to Wiring Diagram Set 29 for schematic and connector information Electrical Diagrams.

Normal Operation and Fault Conditions

The TR (Transmission Range) sensor is a 6-pin connector located inside the transaxle at the manual lever. The TR (Transmission Range) sensor sends a signal to the PCM (Powertrain Control Module) to start the vehicle when the manual lever is in PARK or NEUTRAL. The TR (Transmission Range) sensor contains 4 switches that are monitored by the PCM (Powertrain Control Module) to determine the manual lever (P, R, N, D, L) position.

DTC Fault Trigger Conditions






Pinpoint Test

NOTE: If the scan tool is unable to communicate with the PCM (Powertrain Control Module) or access the transmission PIDs (Parameter Identifications), REFER to Computers and Control Systems Information.

1. Read and record all DTCs (Diagnostic Trouble Codes).

1. Install the scan tool and record all DTCs (Diagnostic Trouble Codes).

Were DTCs (Diagnostic Trouble Codes) P0705, P0706, P0708, P0709, P1702 and/or P1705 set?






2. Check the TR (Transmission Range) sensor circuits for power

1. Ignition OFF.

2. Disconnect the transaxle vehicle harness C168.

3. Inspect the connector for damaged or pushed out terminals, corrosion, loose wires and missing or damaged seals.

4. Ignition ON.

5. Measure the voltage of the TR (Transmission Range) sensor circuits from the transaxle vehicle harness C168 to ground.





Is the voltage greater than 9 volts on all circuits?






3. Check the TR (Transmission Range) sensor ground circuit

1. Measure the voltage between circuit RET24 (BN/BU) from the transaxle vehicle harness C168-8 to transaxle vehicle harness C168-4 circuit VET29 (VT/WH).





Is the voltage less than 9 volts?






4. Check the TR (Transmission Range) sensor circuits for an open.

1. Ignition OFF.

2. Disconnect the PCM (Powertrain Control Module) C175T.

3. Inspect the connector for damaged or pushed out terminals, corrosion, loose wires and missing or damaged seals.

4. Measure the resistance of the TR (Transmission Range) sensor circuits from the transaxle vehicle harness C168 to PCM (Powertrain Control Module) C175T.





Is the resistance greater than 5 ohms?






5. Check the TR (Transmission Range) sensor circuit for a short to ground

1. Measure the resistance of the TR (Transmission Range) sensor circuits from the transaxle vehicle harness C168 to ground.





Is the resistance less than 5 ohms?






6. Check the TR (Transmission Range) sensor circuits shorted together.

1. Measure the resistance of the TR (Transmission Range) sensor circuits from the transaxle vehicle harness C168 to C168 using the following table.





Are all the resistances greater than 10,000 ohms?






7. Check the TR (Transmission Range) sensor solenoid body assembly

1. Remove the main control cover. REFER to Main Control Cover .

2. Measure the resistance of the solenoid body assembly.





Is the resistance less than 0.5 ohms?






8. On demand self-test

1. Check to make sure the transaxle harness connector is fully seated, terminals are engaged in connector and in good condition before proceeding.

2. Connect the scan tool.

3. Make sure the selector lever is in the PARK or NEUTRAL position.

4. Carry out the KOEO (Key ON Engine OFF) self-test.
