If your Taurus won't start or is shifting strangely, the neutral safety switch could be the problem.
- This part is also called a Manual Lever Position Sensor (MLPS) or Transmission Range Sensor (TRS).
- Symptoms include no-start, starting in only Park or Neutral, erratic shifting, and no reverse lights.
- Proper alignment of the new switch during installation is critical for it to function correctly.
- For this vehicle, a quality aftermarket part from a brand like Standard Ignition or Rostra offers a reliable repair without the high cost of OEM parts.
Understanding the Neutral Safety Switch on Your Taurus
When you turn the key in your 1995-2001 Ford Taurus, the neutral safety switch confirms the transmission is safely in Park or Neutral before allowing the starter to engage. Over time, this switch can wear out from use and exposure to heat and moisture. Because this sensor communicates gear position to the main computer, a failure can cause more than just a no-start problem; it can lead to shifting issues and other confusing symptoms.
Symptoms of a Failing Switch
A bad neutral safety switch can make your car seem unreliable. Here are the most common signs of failure:
🎬 Watch: 4 common symptoms of a bad neutral safety switch- No Start or Intermittent Start: You turn the key, and nothing happens. The dashboard lights come on, but the engine doesn't crank. Sometimes, jiggling the shifter might make it start.
- Starts in Neutral but Not Park (or Vice Versa): The switch is failing to send a signal in one of the two starting positions.
- Engine Starts in Any Gear: This is a serious safety hazard. A faulty switch might allow the car to start in Reverse or Drive, causing it to lurch unexpectedly.
- Check Engine Light: The computer may detect a problem with the sensor's signal, triggering a Check Engine Light. Common trouble codes include P0705, P1705, and P1709. 🎬 See how to diagnose these specific transmission error codes
- No Reverse Lights: The switch is also responsible for turning on your backup lights when you shift into Reverse.
- Harsh or Erratic Shifting: If the computer gets the wrong gear position information, the transmission may shift hard, late, or into the wrong gear.
Known Issues and Recalls
Searches of the National Highway Traffic Safety Administration (NHTSA) database show no specific recalls or widespread Technical Service Bulletins (TSBs) for the neutral safety switch on the 1995-2001 Ford Taurus. However, problems with transmission sensors are a known issue on many vehicles of this era due to age and electronic complexity. Always diagnose the problem properly before replacing parts.
Choosing the Right Aftermarket Neutral Safety Switch
For a vehicle like the 1995-2001 Taurus, aftermarket parts offer good value. OEM parts can be difficult to find and expensive. Aftermarket brands provide a range of quality and price points.
- Premium Aftermarket (Example: Standard Ignition): Brands like Standard Motor Products (SMP) have a long-standing reputation for producing high-quality electronic components that meet or exceed original specifications. They are often trusted by professional mechanics for their reliability and durability. This is a good choice if you want the highest quality and longest life from an aftermarket part.
- Mid-Grade Aftermarket (Example: Rostra Powertrain): Rostra is a well-known manufacturer of transmission components and other vehicle electronics. They offer a solid balance of quality and price, making them a reliable choice for a daily driver.
- Standard/Value Aftermarket (Example: Pioneer Cable): These brands provide a functional replacement at a more budget-friendly price. For an older vehicle, this can be a cost-effective way to solve the problem and get your car back on the road.
A Note on Installation
The neutral safety switch is located on the top or side of the transmission. While replacement is possible for an experienced DIYer, it requires removing the airbox for access. 🎬 Watch this step-by-step guide to replacing the switch yourself The most critical step is correctly aligning the new switch. If misaligned, the car may not start or may shift incorrectly. Many switches come with an alignment pin or require using a drill bit to set the position before tightening the bolts. If you are not comfortable with this procedure, it is best to have a professional mechanic perform the installation.

Frequently Asked Questions
Is this part called a neutral safety switch, MLPS, or TRS?
All three names are used. Neutral Safety Switch (NSS) describes its safety function. Manual Lever Position Sensor (MLPS) or Transmission Range Sensor (TRS) describe its job of sensing the gear position. For the 1995-2001 Taurus, they all refer to the same component.
Can I just bypass the neutral safety switch?
While technically possible, it is strongly discouraged. Bypassing the switch creates a major safety risk, as the car could then be started in any gear, leading to accidental movement. It also prevents the computer from knowing the correct gear, which will cause poor transmission performance and other issues.
How do I know if my no-start is the switch or a bad starter?
If the switch is bad, you often hear nothing when you turn the key. If the starter is bad, you might hear a single, loud click. A good test is to try starting the car in Neutral. If it starts in Neutral but not in Park, the neutral safety switch is the most likely cause.
Do I need a special tool to replace this switch?
You will need standard mechanic's tools like sockets and wrenches. The most important "tool" is a small drill bit (often a #43 or similar size) or an alignment pin to properly position the new switch before tightening it down. Failure to align it correctly is the most common installation mistake.
