2014-2019 Nissan Versa Neutral Safety Switch (Range Sensor) Guide
If your Versa won't start, starts in the wrong gear, or has a P0705 code, the neutral safety switch could be the problem.
- A no-start condition is the most common symptom of a bad neutral safety switch on a Versa.
- Always check for Nissan TSB NTB15-082, as a P0705 code can be caused by faulty tail lights, not the switch itself.
- The switch is located on the transmission and requires removing the battery and air intake for access.
- Quality aftermarket brands like Standard Ignition and Rostra are reliable and cost-effective alternatives to OEM.
Is Your Versa's Neutral Safety Switch Failing?
A bad neutral safety switch on a 2014-2019 Nissan Versa can cause some confusing problems. The most common issue is a no-start condition where you turn the key and nothing happens, even though your battery is good. You might also find the car only starts in Neutral, but not in Park (or the other way around). In a more dangerous failure, the switch can short out and allow the car to start in any gear, creating a serious safety risk. 🎬 Watch this overview of neutral safety switch symptoms and fixes. You may also notice your reverse lights don't work or the gear display on your dash is incorrect or missing.
Check This First: TSB for P0705 Code
A very common issue on these Nissan models is the P0705 trouble code, which points to the transmission range sensor. However, Nissan issued a Technical Service Bulletin (TSB), number NTB15-082, that states this code can be falsely triggered by moisture or corrosion in the rear tail light assemblies. Before you replace the neutral safety switch, a mechanic should inspect the tail lights, as replacing them is often the real, and sometimes cheaper, fix.

When replacing the neutral safety switch, you have a choice between the original equipment manufacturer (OEM) part from Nissan and aftermarket options. For the 2014-2019 Versa, aftermarket switches from brands like Standard Ignition (Standard Motor Products) and Rostra Powertrain are widely available.
- OEM: The original Nissan part is a guaranteed fit, but often comes at a higher price. Given the known issues with related electronics (like the tail light TSB), the original part is not necessarily immune to failure.
- Aftermarket: Brands like Standard Ignition and Rostra offer direct-fit replacements that meet or exceed original specifications. They use quality materials like copper alloy conductors for good electrical performance and are a cost-effective alternative to the OEM part. For a part like this, a quality aftermarket brand is a reliable choice for most owners.

Frequently Asked Questions
Where is the neutral safety switch located on a 2014-2019 Nissan Versa?
The neutral safety switch (or range sensor) is mounted on the outside of the automatic transmission, where the shift cable connects. On this front-wheel-drive car, a mechanic will typically access it from under the hood by removing the air intake duct and battery to get enough room to work.
Can I replace the neutral safety switch myself?
This is a moderately difficult job for a DIYer. It requires removing the battery and air intake components to access the switch. The switch itself is held on by two bolts, but the new switch must be properly aligned. Nissan has a special tool (J-52306) for alignment, and while it might be possible without it, incorrect alignment can cause shifting problems. Given the need for proper adjustment, many owners may prefer to have a professional mechanic perform the replacement.
🎬 Follow this DIY guide to replace the range sensor yourself.What is the P0705 trouble code?
P0705 is the diagnostic trouble code for a "Transmission Range Sensor Circuit Malfunction." This means the car's computer is receiving an incorrect or impossible signal from the switch, such as being in Park and Drive at the same time. While a bad switch can cause this, remember to check for the tail light TSB (NTB15-082) as a possible cause on your Versa.
Will a bad neutral safety switch cause transmission problems?
Yes, it can. Besides the no-start issues, a failing switch can cause hesitation upon acceleration or erratic shifting because the transmission control module doesn't know what gear the driver has selected. This can sometimes feel like the transmission itself is failing.
