P0705

Wiring Diagram:

Circuit Description

The transaxie range switch sends gear position signals to the Powertrain Control Module (PCM) according to manual selector range. The PCM uses this information to manage trans axle operation.

Conditions for Setting the DTC

DTC P0705 will set if the following conditions are met:

^ The PCM receives no transaxie range switch signal with the ignition switch ON.

^ or the PCM receives multiple signals simultaneously while in Drive (D) range on 3rd gear for 5 seconds.

^ One driving cycle detection logic.

Action Taken When the DTC sets

A DTC P0705 is stored and the Malfunction Indicator Lamp (MIL) is turned ON.

Diagnostic Aids

Check for the following conditions:

^ Transaxle range switch is out of adjustment.

^ Transaxle range switch malfunction.

^ Faulty electrical circuits (open, short to voltage/ground) between the transaxle range switch and the PCM.

^ Faulty PCM.

An intermittent may be caused by a poor connection, rubbed through wire insulation or a wire broken inside the insulation.

Inspect the PCM harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals and for poor terminal-to-wire connections.

If this DTC cannot be duplicated, the information included in the Freeze Frame data can be useful in determining vehicle operating conditions when the DTC was first set.

If any wiring repairs need to be made, refer to Repair Procedures in Electrical Diagrams.

DTC Confirmation Procedure

1. Turn ignition switch to LOCK.

2. Connect scan tool to Data Link Connector (DLC).

3. Turn ignition switch to ON.

4. Clear DTC, pending DTC and freeze frame data in PCM memory by using scan tool.

5. Start engine.

6. Step fully on brake pedal.

7. Shift manual selector to each of the ranges (R, N, D, 2, L) for 30 seconds each.

8. Drive vehicle to about 70 km/h (44 mph) in Drive (D) range for 30 seconds.

9. Stop vehicle.

10. Check for pending DTC with scan tool.

Test Description

Numbers below refer to circled numbers on the diagnostic chart.

1. The Powertrain OBD System Check prompts the technician to complete some basic checks and store the freeze frame data on the scan tool if applicable. This creates an electronic copy of the data taken when the fault occurred. The information is then stored in the scan tool for later reference.

2. Checks D position signal circuit.

3. Checks L position signal circuit.

4. Checks N position signal circuit.

5. Checks 2 position signal circuit.

6. Checks R position signal circuit.

7. Checks for poor terminal contact at PCM.

8. Checks for faulty PCM.

9. Checks for a short to voltage in D position.

10. Checks for a short to ground in D position.

11. Checks for an open in D position.

12. Checks for an open in YEL wire.

13. Checks for a short to voltage in L position.

14. Checks for a short to ground in L position.

15. Checks for an open in L position.

16. Checks for a short to voltage in N position.

17. Checks for a short to ground in N position.

18. Checks for an open in N position.

19. Checks for a short to voltage in 2 position.

20. Checks for a short to ground in 2 position.

21. Checks for an open in 2 position.

22. Checks for a short to voltage in R position.

23. Checks for a short to ground in R position.

24. Checks for an open in R position.
