DIAGNOSIS AND TESTING - PARK/NEUTRAL POSITION SWITCH
The park/neutral starting switch is the center terminal of the 3 terminal switch. It provides ground for the starter solenoid circuit through the selector lever in only Park (P) and Neutral (N) positions.

2. Check gearshift cable adjustment before replacing a switch which tests bad.
