Chrysler Voyager Neutral Safety Switch Guide: 1999-2003
If your Voyager won't start or the reverse lights are out, the neutral safety switch could be the problem.
- A bad neutral safety switch can make your Voyager not start or create a safety hazard by allowing it to start in gear.
- Symptoms include no-start, no reverse lights, and a P0705 check engine code.
- For this vehicle, replacement can be complex if the part is inside the transmission, so professional diagnosis is recommended.
- A quality aftermarket brand like Standard Ignition is a reliable and cost-effective alternative to an OEM part.
Symptoms of a Failing Neutral Safety Switch
When the neutral safety switch (also called a transmission range sensor) starts to fail on your Voyager, it can cause some confusing problems. Recognizing these signs can save you from replacing the wrong parts.
🎬 Watch this video to identify common neutral safety switch symptoms.- No-Crank, No-Start: This is the most common symptom. You turn the key, the dashboard lights up, but the engine doesn't crank. You might find that it starts in Neutral but not in Park, or you have to jiggle the shifter to get it to start.
- Starts in Any Gear: This is a serious safety risk. A bad switch might allow the engine to crank while in Drive or Reverse, causing the van to move unexpectedly.
- Reverse Lights Don't Work: The switch controls the backup lights. If they don't come on when you shift into Reverse, the switch is a likely culprit (after checking the bulbs and fuses).
- Check Engine Light: A failing switch can trigger the check engine light. A common trouble code associated with this part is P0705, which indicates a malfunction in the transmission range sensor circuit. 🎬 Learn about the six main signs of a failing switch.
Rule Out Other Issues First
A no-start condition can also be caused by a dead battery, a bad starter, or a faulty ignition switch. It's important to make sure these components are working correctly before deciding to replace the neutral safety switch.
Choosing the Right Aftermarket Switch
For a 1999-2003 Voyager, the original Mopar part may be hard to find or expensive. Aftermarket parts are a practical choice. The key is to choose a brand with a good reputation.
- OEM (Mopar): Original parts are designed for your vehicle, but they are the most expensive option. A genuine Mopar Transmission Range Sensor can cost over $60.
- Premium Aftermarket (Standard Ignition): Brands like Standard Motor Products (SMP) are well-respected in the auto repair industry. They produce parts that are designed to meet or exceed original specifications, offering a balance of quality and cost. For this repair, a Standard Ignition switch is a reliable choice that mechanics trust.
Pro Tip: The neutral safety switch on some 1999-2003 Voyagers is located inside the transmission oil pan and is part of the valve body assembly. This makes replacement more difficult than on vehicles where it is mounted externally. Always confirm the location on your specific vehicle before starting the repair. Some sources indicate it is on the outside of the transmission for this generation.

Frequently Asked Questions
Can I replace the neutral safety switch myself?
This depends on its location. If the switch is on the outside of the transmission, it is a job a DIY mechanic can handle with basic tools. However, if it is located inside the transmission pan, it requires draining the fluid and removing the valve body, which is a more complex job best left to a professional.
What is the difference between a Neutral Safety Switch and a Transmission Range Sensor?
For the 1999-2003 Voyager, these terms are often used for the same part. The component performs the safety function of only allowing the engine to start in Park or Neutral, and it also senses the full range of gear positions (P, R, N, D, etc.) for the computer.
Is there a recall for the neutral safety switch on my Voyager?
No, there are no specific safety recalls on the NHTSA database for the neutral safety switch on 1999-2003 Chrysler Voyager models. Any recalls found are for much newer model years and different components.
Can I just bypass the neutral safety switch?
Bypassing the switch is strongly discouraged. While it might be a temporary fix to get the vehicle started, it disables a critical safety feature. This would allow the van to start in any gear, creating a serious risk of it lurching forward or backward unexpectedly.
