What does the neutral switch do on a car?
What Is The Neutral Safety Switch? It’s a safety feature built into an automatic transmission that doesn’t allow the vehicle to start while in gear – reverse or drive. The vehicle will start if the transmission lever is placed in park or neutral, both of which will not allow it to move forward when it’s turned on.
How can I tell if my neutral switch is faulty?
Another fairly obvious way you can tell if the neutral safety switch is faulty is if your car won’t start when it’s in park, but will start when shifted into neutral. Most vehicles today won’t allow the key to be removed if it’s in any gear except park.

When this occurs, it’s a serious safety hazard, as essentially it’s as if there is no neutral safety switch installed on your vehicle. In this case, the safety switch must be replaced as soon as possible to avoid serious accidents or injuries.
Can a car stall with a bad throttle position sensor?
The engine can stall for no reason and without any warning. This happens when the TPS gives incorrect information to the ECM. The engine can stall at high speed, at low speed, or even at idle. A faulty throttle position sensor will not let your car accelerate normally. Though this doesn’t happen all the time.
How much does a neutral safety switch cost?
A new neutral safety switch doesn’t cost that much – usually between $100 and $400 – and a mechanic will have all the necessary tools to do the job at their disposal. Labor costs will also usually be reasonable, as the job doesn’t involve tearing apart any major components.
What to do if your neutral switch is faulty?
To test this, simply place the vehicle in neutral and try to start it. If it doesn’t start, the neutral safety switch may be faulty. Another more difficult symptom you can look out for to diagnose a problem is when you can fully start your vehicle in any gear or shift lever position.
Is the neutral safety switch as important as airbags?
The neutral safety switch is still a little different, though. It might not be quite as important as airbags and seat-belts, yet not all drivers know what it is or how important of a safety feature it is.
