2011-2017 Nissan Quest Automatic Transmission Output Speed Sensor Guide
Experiencing hard shifting or a dead speedometer in your Quest? The output speed sensor is a likely culprit.
- A failing output speed sensor is a common cause for harsh shifting and speedometer issues in the 2011-2017 Quest.
- The most common trouble code is P0720, which points directly to the output speed sensor circuit.
- This is a DIY-friendly repair, located on the outside of the transmission and held by a single bolt.
- Driving is not recommended as the van can enter a low-power 'limp mode' or shift unpredictably at any time.
Is Your Nissan Quest Shifting Hard or Acting Unpredictable?
A failing automatic transmission output speed sensor is a common issue that can make your 2011-2017 Nissan Quest difficult and unsafe to drive. Because this sensor provides essential speed data to the Continuously Variable Transmission (CVT), a bad signal can cause a host of problems, from jerky shifting to a complete loss of power. Understanding the symptoms and your replacement options can help you get your Quest running smoothly again.

Symptoms of a Failing Output Speed Sensor
When the output speed sensor begins to fail, your Quest will give you clear signs. Ignoring them can put extra strain on the CVT. Here’s what to look for:
🎬 Watch this video to see common signs of sensor failure.- Harsh or Erratic Shifting: The transmission may feel like it's banging into gear, shifting at the wrong moments, or feeling generally jerky. This is one of the most common signs of a bad speed sensor.
- Faulty Speedometer: The speedometer needle might jump around, show an incorrect speed, or stop working completely.
- Check Engine Light: A failing sensor will almost always trigger the Check Engine Light. The most common code associated with this failure is P0720, which points directly to the output speed sensor circuit.
- Stuck in "Limp Mode": To protect itself from damage, the transmission may default to a single gear. This results in a major loss of acceleration and power, making it difficult to drive.
- Cruise Control Not Working: Since the cruise control system needs accurate speed data to function, it will become disabled if the sensor fails.
Choosing the Right Aftermarket Part
For a critical sensor like this, part quality matters. While an OEM sensor from a Nissan dealer is an option, high-quality aftermarket parts provide a reliable repair at a better price. The 2011-2017 Quest is known for CVT issues, and using a low-quality, cheap sensor can lead to continued problems or premature failure.
Pro Tip: Your Quest has both an input and an output transmission speed sensor. The symptoms and the P0720 code described here point to the output sensor. Ensure you are ordering the correct part to avoid delays with your repair.
Brand Tiers
- Premium Aftermarket (e.g., Standard Ignition): Brands like Standard Motor Products (SMP) are well-regarded in the industry for producing parts that meet or exceed OEM specifications. They undergo extensive testing and use high-quality materials, making them a reliable choice for a critical component like a speed sensor.
- Standard Aftermarket (e.g., True Tech): These parts offer a balance of value and quality. They are a good alternative to the cheapest options on the market and are designed to be a direct-fit replacement.
A Note on Nissan CVT Transmissions
The CVT in the 2011-2017 Quest can be sensitive. Problems like shuddering, hesitation, and premature failure are widely documented by owners. While a faulty speed sensor is a common and relatively simple fix, it's important to be aware of the broader issues associated with these transmissions. Regular maintenance, including fluid changes, is crucial.
