Understanding the Neutral Safety Switch (NSS)
The neutral safety switch is a crucial component in your vehicle’s starting system. Its primary function is to prevent the engine from starting unless the transmission is in the park (P) or neutral (N) position. This safety feature protects against accidental acceleration and potential injury. The NSS acts as a simple on/off switch, completing the electrical circuit only when the transmission is in park or neutral. A malfunctioning NSS can manifest in a variety of ways, from intermittent starting problems to a complete inability to start your car.
How the NSS Works
The NSS is mechanically linked to your transmission’s shift lever. A small plunger inside the switch moves according to the transmission’s position. When the lever is in park or neutral, the plunger is pushed into a position that closes the electrical circuit, allowing the starter motor to engage. In all other gears, the plunger is out of position, preventing the circuit from closing and thus blocking the engine’s start-up.
Diagnosing a Faulty or Misadjusted Neutral Safety Switch
Before diving into any adjustments, it’s vital to correctly diagnose the problem. A misadjusted NSS might cause the symptoms of a completely failed switch.
Common Symptoms of a Faulty or Misadjusted NSS
- Intermittent Starting Problems: The car starts sometimes but not others, especially when the key is turned quickly or the gear selector is jiggled slightly.
- Inability to Start: The car simply will not crank at all, irrespective of the key position.
- Starter Motor Engagement in Gear: This a serious safety issue where the engine attempts to crank even when the transmission is in gear. This can cause significant damage.
- Check Engine Light: Though not always the case, a malfunctioning NSS can trigger the check engine light.
Testing the NSS
A simple test involves using a multimeter to check for continuity. Consult your vehicle’s repair manual for specific instructions on testing your NSS. This manual also provides diagrams of the switch’s location and wiring schematics. Remember to disconnect the negative battery terminal before beginning any electrical testing.

Locating Your Neutral Safety Switch
The location of your neutral safety switch varies depending on the make, model, and year of your vehicle. Generally, it’s located near the transmission, often on the side or bottom. Consult your vehicle’s repair manual for the exact location. It’s often a small, cylindrical component with electrical connectors attached.
Accessing the NSS
Once located, you may need to remove some components to access the switch for adjustment or replacement. This could involve removing parts such as the transmission linkage, or in some cases the bottom cover of the transmission. Again, reference your vehicle’s repair manual for specific instructions. Always use caution and appropriate safety tools when working around moving parts or electrical connections.
Adjusting the Neutral Safety Switch: A 5-Step Guide
Note: This is a general guide. The specific steps may vary slightly depending on your vehicle’s make and model. Always consult your vehicle’s repair manual for precise instructions. Improper adjustment can lead to further damage or safety hazards.
- Disconnect the Battery: Always disconnect the negative battery terminal before performing any repairs involving the electrical system. This prevents accidental shorts and protects against potential electrical shocks.

- Adjustment (If Necessary): If the switch appears undamaged, you may be able to adjust its position. Most NSS’s have a small adjustment screw or linkage that allows for slight movement. Carefully adjust this, checking the continuity with a multimeter at each adjustment. This ensures the circuit is only closed when the transmission is in park or neutral. Small adjustments are key; avoid excessive force.
- Reconnect and Test: After making adjustments, reconnect the battery and test the vehicle’s starting system. Ensure that the car starts only when the transmission is in park or neutral, and does not start in any other gear. If problems persist, the NSS might require replacement.
Neutral Safety Switch Adjustment: Common Issues
Sometimes, even with careful adjustment, the neutral safety switch may still malfunction. Poor wiring connections, corrosion in the switch itself, or a damaged plunger can all contribute to problems. In these cases, replacement is often the most effective solution.
Replacing the Neutral Safety Switch
If adjusting the switch doesn’t solve the problem, replacement is necessary. This process involves disconnecting the electrical connectors, removing the retaining bolts or clips holding the switch in place, and installing a new switch. Ensure the replacement switch is the correct type for your vehicle. Again, your vehicle’s repair manual will provide detailed instructions. [Link to an online auto parts store].
