DTC P0705 - TRANSMISSION RANGE SWITCH CIRCUIT (L81) MY 2001





The transmission range switch is a multi-signal switch which sends a signal to the TCM to indicate gear selection. The transmission range switch uses four discrete circuits to change four TCM input voltages in various combinations to indicate each gear range. The voltage level of the circuits is represented as OFF = open circuit, ON = switch closed. The four states displayed represents the encoder P, A, B and C inputs in sequence.

DTC PARAMETERS
- The TCM recognizes an invalid PRNDL parameter.
- The vehicle speed is greater than 8 km/h (5 mph).
- The above conditions met for greater than five seconds.

DIAGNOSTIC AIDS
- Monitor Scan tool while moving the related connectors and wiring harness. If a malfunction occurs, the Scan data will change states from either ON to OFF or from OFF to ON. Move the gear selector slowly through each gear while monitoring the Scan tool in order to help isolate the problem.





- When DTC P0705 sets, the TCM defaults to 4th gear until the TCM receives a correct combination. Therefore, some of the selected gear positions may not be possible until the malfunction is repaired.
