TRANSAXLE RANGE SWITCH CIRCUIT
Transaxle Range Switch (TRS) is part of Park/Neutral Position
(PNP) switch. Inputs from TRS indicate to PCM which position is
selected by gear selector lever. PCM uses this information for
ignition timing, EVAP canister purge, EGR and IAC valve operation.
Combination of 4 TRS input states determine PCM commanded
shift pattern. Input voltage level at PCM is high when TRS is open,
and low when TRS is closed. A problem which causes PCM to detect an
invalid transaxle range input combination will set DTC P0705.
You likely won't notice any drivability problems.
- TRS inputs indicate an invalid combination for more than
- Check if TRS 4-pin harness connector is disconnected or
- Check for faulty connection at TRS 4-pin and 7-pin
- Replace TRS.
