Default P0706

P0706

Description
TRANSAXLE RANGE SYSTEM PERFORMANCE


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. If PCM detects engine start-up in any gear
other than Park or Neutral, DTC P0706 is set.

Symptoms
You likely won't notice any drivability problems.

Causes
  • TRS inputs indicate a gear position other than Park or
    Neutral during start-up.
Solutions
  • If DTC P0705 is also set, diagnose DTC P0705 before
    proceeding.
  • Check for faulty connection at TRS 4-pin and 7-pin
    connectors.
  • Replace TRS.
