The neutral safety switch is often an overlooked component of a vehicle. When you go to start your engine, the gear must be set to Neutral or Park. Most people will already have their gear set to Park from when they parked their car before and that is fine. However, automatic transmission systems are built with a safety component which prevents you from starting the engine if the gear is set to another gear other than Neutral or Park. This component is the neutral safety switch.

For instance, if you inadvertently set the gear to Drive and then try to start the engine, the neutral safety switch will prevent the engine from starting. That way, the vehicle will not glide forward right afterward. In an automatic transmission vehicle, the neutral safety switch is typically placed inside the case of the transmission. It may also be integrated into the linkage which gives the transmission its ability to change gears. As long as the gear is at Neutral or Park, the neutral safety switch will let the ignition switch send its electrical current to the ignition system and starter motor.

Manual transmissions have a different component that acts in a similar manner as the neutral safety switch. This component is installed in the clutch of the vehicle and it prevents the engine from being started if the clutch pedal is not pressed.

Top 4 Symptoms of a Bad Neutral Safety Switch

If you have a bad neutral safety switch, it could cause irreversible damage to your engine and/or transmission. That is why you need to recognize the symptoms of a bad neutral safety switch. Then you will know when to bring your vehicle to the mechanic so that they can replace your neutral safety switch with a new one.

Below are the top 4 symptoms of a bad or faulty neutral safety switch.

No Park Cranking – If you have set the gear to park in your automatic transmission and the engine does not crank after you turn the key in the ignition, then you probably have a problem with your neutral safety switch. Of course, you might not recognize this problem as being directly connected to your neutral safety switch because the same symptom can occur from a bad battery or starter motor.

No Neutral Cranking – Sometimes the engine might crank in park but not in neutral. This is another possible symptom of a neutral safety switch problem. The switch itself might still be in good shape, but it could be loose in the transmission or there could be an electrical issue that is preventing the switch from receiving power.

No Park or Neutral Cranking – If your neutral safety switch is having serious electrical problems, then your engine will not crank in park or neutral. The starter relay relies on the switch for receiving power. If it can’t receive this power, then the starter motor will not be able to crank the engine.

All Gears Crank – The most obvious symptom of a bad neutral safety switch is when you can crank the engine in any gear. You could have the gear set to Drive or Reverse and still be able to crank it. If the engine is running, you will be able to crank it again too. This could lead to a serious car accident if this happens while you’re driving.

Replacement Cost

The replacement cost of a neutral safety switch is anywhere from $95 to $150. The parts cost will be around $50 while the labor costs will be between $45 and $100. As you can see, this is a very affordable replacement job to get done. The cost of the part is cheap and since it doesn’t take long for the mechanic to perform the replacement, their labor costs will be cheap too.
