One of following is met

1.

NSW input signal

2.

P input signal

3.

R input signal

4.

N input signal


2.

One of following is ON.

1.

3 input signal

MONITOR DESCRIPTION

The park/neutral position switch detects the gearshift position and sends a signal to the ECM.

For security, the park/neutral position switch detects the gearshift position so that engine can be started only when the shift lever is in P or N.

When the park/neutral position switch sends more than one signal at a time from switch positions P, R, N, D, 3, 2 or L the ECM interprets this as a fault in the switch. The ECM will illuminate the MIL and store this DTC.
