Signs and symptoms of a defective neutral safety switch

All new vehicles use some type of safety neutral switch to prevent the car from starting while in gear. This switch on most vehicles is attached either by the shift mechanism inside the transmission or that of the shifter itself. This failure can easily immobilize the vehicle or can cause it to start in gear.

Starter Failure

Although specific designs vary, this switch typically acts as a switch between the starter and starter relay, or the key and distributor to start. During normal operation, the internal circuitry of the control will only close in the neutral or park position. In no other position can it be forced to do so from the ignition key to the starter regulator or circuit breaker. If your vehicle’s ignition does not engage in any way when the key is turned to park or neutral, the neutral safety button may be at fault.

Check the code and the check engine light

This safety neutral switch is an important component in preventing injury and death, so it may be part of the vehicle’s diagnostic circuitry. The manufacturer may have built a feedback circuit into the starter or transmission system, which allows the computer to diagnose the problem and notify you through a check engine light. If you suspect this switch is faulty and find that light illuminating, have a technician read the codes with a scanner. Many chain auto parts stores will pull and erase the codes on your car for free, but you’ll have to get there first.

Starter Switches

Modern safety neutral switches are default off design, which means this switch may fail when you want to immobilize the vehicle instead of allowing it to start in gear. However, it is not impossible for the contacts to cross due to moisture in the switch, metal debris, physical damage, wear metal shavings, or any number of other faults. If this occurs, the power side of the control terminal will cut against the box or power output terminal to the starter motor, allowing the vehicle to start in gear. Older switches may not incorporate a predetermined default design, so the fault may manifest as a constant on start in gear.

Moving the shift lever

One way to diagnose a faulty safety neutral switch is to place the shift lever in park or neutral, then try starting the engine while gently moving the lever so far out of gear. This will activate a different part of the contact inside your switch, allowing power to pass through the starter relay. If your vehicle does not start while you move the lever, then you need to replace the switch.
