Park Neutral Position Switch

Neutral Safety Switches And Starting

A neutral safety switch is part of the starting interlock on many automatic-transmission vehicles. It provides a position-related signal so the starting system can recognize the appropriate selector position. Some applications call the part a park/neutral position switch or transmission range switch.

A-Premium lists switches for selected vehicles and transmission types. Match the vehicle and transmission specification as well as the connector and mounting arrangement; similarly named switches do not all have the same connections.

Choosing A Neutral Safety Switch Replacement

The correct switch can depend on transmission design, engine or other application details. Some Honda Accord and Civic entries specify a continuously variable transmission, while a particular Chevrolet application limits the engine size. Use the note for the exact listing and vehicle.

If an engine will not crank or the indicated gear seems incorrect, the switch is one possible cause. Battery condition, wiring, selector linkage and other starting components can also require diagnosis. Keep the starting interlock functional; do not bypass it to make the vehicle start.
