DTC 1003

Park/Neutral Position Switch (DTC: 1003)

DESCRIPTION
When the gear position is in "P" (A/T models only) or "N", park/neutral position is "ON". For M/T models, the "ON" signal (or line continuity) is detected by the ECM, whereas the A/T control unit detects it for A/T models. The A/T control unit then sends the park/neutral signal to ECM.
