Methods for Bypassing the neutral safety switch!

neutral safety switch

A neutral safety switch is a car’s safety feature that prevents the engine from starting unless the transmission is in neutral or Park. However, in some situations, bypassing the neutral safety switch may be necessary to start the engine. 

Symptoms of a bad neutral safety switch include the engine only cranking in Park or Neutral, no cranking in either Park or Neutral, engine cranking in all gears, and backup lights not turning on in Reverse.

Bypassing the switch on a manual transmission is a relatively simple process that involves connecting two wires under the clutch pedal. Still, it should only be done for testing or in an emergency. However, bypassing a neutral safety switch with automatic transmission will be difficult. Only a professional mechanic would do better in that case.

Bypassing the switch can be dangerous as the starter motor may crank the engine while the vehicle is in gear, which could lead to an expensive, harmful, or even deadly situation. 

Therefore, cleaning, repairing, or replacing the neutral safety switch is recommended instead of bypassing it permanently.

What is a neutral safety switch?

A neutral safety switch, also called a transmission range sensor, is a safety feature in a vehicle that prevents the engine from starting unless the transmission is either in “Park” or “neutral”.

It is usually located on the information and sends a signal to the vehicle’s computer to allow the engine to start. If the switch is faulty or not in the correct position, the car may not start or may start in a different gear, such as Reverse or drive. The neutral safety switch is an important vehicle safety system component.

Symptoms of a bad neutral safety switch

1.   Engine only cranks in Park.

The first symptom of a bad neutral safety switch is when the engine only cranks in Park. A neutral safety switch should also allow the engine to crank in Neutral. If the engine only cranks in Park and not Neutral, it may indicate that the neutral safety switch must be replaced.

2.   Engine only cranks in Neutral.

The second symptom of a bad neutral safety switch is when the engine only cranks in Neutral. A properly functioning neutral safety switch should allow the engine to crank in Neutral or Park. If the engine only cranks in Neutral, it may indicate that the neutral safety switch needs to be replaced.

3.   No cranking in Park or Neutral

The third symptom of a bad neutral safety switch is no cranking in either Park or Neutral. If the dash lights and radio turn on, but the engine does not crank, it may indicate that the neutral safety switch needs to be replaced.

4.   Engine cranks in all gears

The fourth symptom of a bad neutral safety switch is when the engine cranks in all gears. If the engine can be cranked and driven in any equipment, it may indicate that the neutral safety switch needs to be replaced. It is not recommended to drive the vehicle in this condition.

5.   Backup lights don’t turn on in Reverse.

If your car’s backup lights don’t turn on when you are reversing then, this can be due to a bad neutral safety switch as well. While this may not occur in all cars, if it does happen, it can indicate that the neutral safety switch needs to be replaced.

How to bypass the neutral safety switch on the automatic transmission?

There can be some risks associated with bypassing the neutral safety switch. You can replace it with a new one instead of circumventing it. You can purchase a neutral safety switch anywhere online. However, if you still want to learn how to avoid a neutral safety switch with automatic transmission, here are all the steps to note:

  • Locate the neutral safety switch on the automatic transmission first. The button is frequently located next to the shift linkage or on the gearbox housing. By studying the owner’s manual for your car or seeking assistance from a reputable mechanic, you can determine the switch’s specific location.
  • Then, the electrical connector attached to the neutral safety switch should be disconnected. 
  • The clips or nuts holding the connector in place can typically be removed by using a wrench or socket. Pull the connector away from the switch with caution.
  • Decide which wires go to the neutral safety switch. Look for the wires that attach to the control; these should include the ones that go to the ignition switch and the starter solenoid, respectively. Make sure there is no voltage present in the wires before disconnecting them.
  • Use an alligator clip or jumper wire to connect the cables. Connect each of the wires previously connected to the neutral safety switch using one end of a jumper wire or alligator clip. Use wire nuts or electrical tape to fix the connection securely.
  • Try to start the car by turning on the ignition. The neutral safety switch has been effectively disregarded if the vehicle starts in any gear. However, it’s crucial to remember that bypassing the regulator can be risky and is not advised.
  • Replace any parts that were taken out during the procedure and reattach the electrical connector to the neutral safety switch. You check that everything works as it should and make sure you thoroughly test the vehicle. Remember that to make sure the neutral safety switch is functioning properly; it is always advised to fix or replace it.

How to bypass the neutral safety switch on a manual transmission?

So, this manual transmission will work on cars with a neutral safety switch towards the clutch pedal. This is very easy and anyone with a little knowledge of the car’s mechanism can do it easily.

One must first ascertain which wires go into the control and which must be connected to bypass the neutral safety switch on a manual transmission. The two wires that enter the switch should then be connected using a piece of wire or a paperclip. This will allow the vehicle to start even with the neutral safety switch off.

It is crucial to remember that this is simply a short-term fix though. To prevent any potential safety risks, the switch needs to be fixed or replaced as quickly as feasible.

It is essential to exercise caution when bypassing the neutral safety switch, as the starter motor can still crank on even if the car is in gear, which can be dangerous or even deadly. Therefore, it is essential to only use this procedure for testing purposes or in an emergency.

How much does it cost to replace the neutral safety switch?

The cost to replace a neutral safety switch can vary depending on location, the vehicle makes and model, and the mechanic you choose. The average cost for a neutral safety switch replacement is between $120-$150. Labor costs are estimated between $60-$70, while parts are priced between $30-$60.

For manual transmission, you might not have to pay much. The switch will cost you around $30 and $50-$60 on the labor.

Final Thoughts

It can be difficult to bypass the neutral safety switch for automatic transmission vehicles. Only a highly skilled mechanic can complete it. Due to differing wiring in various cars, it can be challenging to figure out which pins are for the neutral safety switch and connect them.

It is crucial to highlight that bypassing the switch might be risky and should only be done for testing or in an emergency.

Before attempting to bypass the switch, one should know the safety ramifications. Connecting the two wires on the clutch switch allows a manual gearbox car to avoid a button easily.

To ensure the proper operation of the vehicle’s safety system, it is strongly advised to put safety first and to obtain professional assistance for any repairs or replacements.

FAQs

A: Both automatic and manual transmissions have a fuse for the neutral safety switch. The fuse is in the box, also known as the power distribution center, which is usually situated in the engine compartment, center console, or steering wheel.

Always use the correct size fuse because too much electricity could result in electrical or circuit problems. Since fuses are only intended for one usage, they must be replaced if they blow.

A: Yes, automatic transmissions have a neutral safety switch. An automatic gearbox has a safety device that prevents the car from starting while driving or Reverse. The car will start if the transmission lever is in neutral or Park, which prevents the vehicle from moving forward when it is created.

A: A damaged neutral safety switch may damage a car’s transmission. The vehicle’s engine cannot start unless it is in the park or neutral, thanks to the neutral safety switch.

Switch problems that result in the gearbox not receiving the proper signal could result in problems like stalling or complex gear changes. Additionally, the gearbox may sustain harm if the switch isn’t working correctly, yet the car can still start in gear.
