DTC P0705 - TRANSMISSION RANGE SWITCH CIRCUIT (L61) MY 2000





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

DTC PARAMETERS
- The PCM recognizes an invalid PRNDL parameter.
- The vehicle speed is greater than 8 km/h (5 mph).
- The above conditions are 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 tool 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 PCM defaults to 4th gear until the PCM receives a correct combination. Therefore, some of the selected gear positions may not be possible until the malfunction is repaired.
