Nissan NP300 Engine Crankshaft Position Sensor Guide (2009-2020)
Solve stalling and no-start problems in your NP300 by understanding and choosing the right crankshaft position sensor.
- A failing sensor will cause a no-start or stalling condition; do not drive the vehicle if you suspect it's bad.
- The most common diagnostic code is P0335.
- For reliability, choose an OEM (Nissan), Hitachi, or NGK/NTK brand sensor; cheap aftermarket sensors are known to fail on these trucks.
- Replacement is DIY-friendly and located on the passenger side of the transmission bellhousing.
Is Your NP300 Stalling or Refusing to Start? It Could Be the Crankshaft Sensor.



If your 2009-2020 Nissan NP300 suddenly stalls while driving or cranks but won't start, a failed crankshaft position sensor is a very common cause. This sensor is critical for engine operation, and when it fails, it can leave you stranded. This guide will help you understand the symptoms, choose the best replacement part, and know what to expect for repair costs.
Symptoms of a Failing Crankshaft Sensor
A bad crankshaft sensor sends wrong information, or no information, to your engine's computer. This can cause several noticeable problems. The most common issue is the engine cranking but not starting. You may also experience the engine stalling unexpectedly while driving, which can be dangerous.
- Check Engine Light: A failing sensor will almost always turn on the Check Engine Light. The most common trouble code is P0335. 🎬 See how to quickly diagnose and fix the P0335 code.
- Engine Won't Start: The engine turns over but never fires up. 🎬 Watch how a faulty sensor causes long cranking and RPM issues.
- Sudden Stalling: The engine shuts off without warning while idling or driving.
- Rough Running: You may feel a rough idle, engine shaking, or misfires.
- Poor Performance: The truck may struggle to accelerate or feel low on power.
- Worse Gas Mileage: When the engine doesn't run efficiently, it uses more fuel.
Safety Warning: Do Not Drive
It is not safe to drive with a faulty crankshaft position sensor. The risk of the engine stalling at any time, including at high speeds or in traffic, is a serious safety hazard. If you suspect your sensor is failing, get it replaced as soon as possible.
Choosing the Right Aftermarket Sensor
When replacing a critical sensor on a Nissan, part quality matters a lot. While saving money is tempting, a cheap, low-quality sensor can fail quickly, forcing you to do the job all over again. Forum discussions among Nissan owners show a strong preference for using the original manufacturer's parts or high-quality equivalents.
Brand Quality Tiers
- Top Tier (OEM or Equivalent): Genuine Nissan parts are the safest bet. However, the company that makes the original sensor for Nissan is often Hitachi. Buying a Hitachi sensor gives you OEM quality, often for less money. NGK (NTK) is another brand widely trusted by mechanics and considered to be OEM-level quality for sensors.
- Mid-Grade (Reliable Aftermarket): Brands like Standard Ignition (SMP) and Walker Products are established aftermarket manufacturers. They are generally considered reliable options if a top-tier brand is not available, but some mechanics have reported occasional issues.
- Economy Tier (Use with Caution): Lower-cost brands like True Tech or other store brands are a gamble. While the price is low, the failure rate for critical sensors like this is higher. It is generally recommended to invest in a better-quality part to ensure reliability.
Pro Tip: Check the Part Number
The crankshaft sensor for the 2.4L (KA24DE) engine in the D22 platform NP300 is often listed under part number 23731-3S500 or similar variants. Always confirm the exact part number for your specific vehicle before ordering to avoid mistakes.
Replacement Cost
The cost to replace the crankshaft sensor is reasonable, especially if you can do it yourself. The part itself is not expensive, and the labor is straightforward for a mechanic.
