DTC P0705: Transmission Range Switch (Multiple Shift-position Input)

NOTE: This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

1. Turn the ignition switch to ON (II).

2. Compare the ATPP, ATPR, ATPN, ATPD, ATPS, ATPFWD, and ATPRVS inputs with the HDS to the following table, in each gear position.









Do the transmission range switch signals match?
YES - Intermittent failure, the system is OK at this time.

NO - Go to step 3.


3. Compare the ATPP, ATPR, ATPN, ATPD, ATPS, ATPFWD, and ATPRVS inputs with the HDS to the table in step 2, in each gear position.

Are any transmission range signals ON in all shift lever positions?
YES - Go to step 7.

NO - Go to step 4.


4. Disconnect the transmission range switch connector.

5. Connect the transmission range switch connector terminal which incorrectly indicates ON in step 3 to body ground with a jumper wire.

6. Compare the ATPP, ATPR, ATPN, ATPD, ATPS, ATPFWD, and ATPRVS inputs with the HDS to the table in step 2.

Do multiple transmission range switch signals indicate ON?
YES - Repair short in the wires between the transmission range switch and the PCM. Refer to the following table.

NO - Replace the transmission range switch. Service and Repair






7. Disconnect the transmission range switch connector.

8. Check the abnormal transmission range switch signal with the HDS.

Do any transmission range switch signals remain ON?
YES - Go to step 9.

NO - Replace the transmission range switch. Service and Repair


9. Check continuity to body ground in the circuit which remained ON, refer to the table in step 2.

Does the circuit that indicated ON have continuity to ground?
YES - Repair a short to body ground in the wire between the transmission range switch and the PCM.

NO - Replace the PCM.
