- Engine Stalls Unexpectedly: The engine may shut off while you are driving, which is a major safety hazard. This can happen randomly at any speed or when idling.
- Engine Cranks but Won't Start: This is one of the most common symptoms. The starter will turn the engine over, but it won't fire up because the computer doesn't know when to create a spark.
- Check Engine Light: A failing sensor will trigger the Check Engine Light. A common trouble code associated with this issue is P0335 (Crankshaft Position Sensor "A" Circuit Malfunction).
Other Common Symptoms:
- Rough Idling: The engine may vibrate or run unevenly when the vehicle is stopped.
- Poor Acceleration: Your Nitro may feel sluggish and lack power when you press the gas pedal.
- Decreased Fuel Economy: Incorrect timing signals can cause the engine to use more fuel than necessary.
- Engine Misfires: You may feel the engine stumble or hesitate.
Choosing the Right Aftermarket Sensor
When replacing a critical electronic part like a crankshaft sensor, quality makes a difference. While budget parts are available, they may not last, leaving you with the same problem again. Here’s a breakdown of brand tiers to help you choose.
Tier 1: Premium Aftermarket & OEM Suppliers
These brands often manufacture parts for car companies directly and are known for their reliability and high-quality standards. They are your best bet for a long-lasting repair.
- Delphi: A major OE supplier with a strong reputation for quality electronics.
- NGK / NTK: Highly respected for sensors and ignition components, considered a top-tier choice.
- Hitachi: Another well-regarded OE supplier known for excellent electronic parts.
Tier 2: Reputable Aftermarket Brands
These brands offer a good balance of quality and value. They are a solid choice for most DIY repairs.
- Standard Motor Products (SMP): A long-standing, reliable name in the aftermarket.
- Dorman: Known for providing a wide range of aftermarket parts that often include design improvements over the original.
- Walker Products: A well-known brand for fuel and engine management parts.
Tier 3: Economy Brands
Brands like Crown, Prenco, or True Tech fall into this category. They offer the lowest price point but may have a shorter lifespan and less consistent quality. They can be a solution for a tight budget, but a premium brand is recommended for this specific part.
Pro Tip: Before you replace the sensor, always inspect the wiring and connector. A loose connection, corrosion, or damaged wire can mimic the symptoms of a failed sensor. Cleaning the connector or repairing a wire could save you the cost of a new part.

Frequently Asked Questions (FAQ)
Where is the crankshaft position sensor located on a 2007-2012 Dodge Nitro?
The crankshaft position sensor on both the 3.7L and 4.0L V6 engines is located on the passenger side of the engine block, near the rear where the engine meets the transmission. You will need to access it from underneath the vehicle.
Is it difficult to replace the crankshaft sensor myself?
For a DIYer with some experience, this is a manageable job. It involves raising the vehicle safely, disconnecting the electrical connector, and removing a single bolt. However, the sensor can be difficult to remove if it's seized in the engine block. It may require careful twisting and wiggling to get it out. Applying a small amount of clean oil to the O-ring of the new sensor will help with installation.
Are there any recalls for this part on the Dodge Nitro?
No, there are no specific recalls for the crankshaft position sensor itself on the 2007-2012 Dodge Nitro. Searches of the NHTSA database found recalls related to the tone wheel that the sensor reads on some other Chrysler vehicles with diesel engines, but these do not apply to the gas-powered Nitro.
Should I replace the camshaft position sensor at the same time?
It is not required, but it is often recommended, especially on higher-mileage vehicles. The camshaft and crankshaft sensors work together, are of a similar age, and a failure in one can sometimes affect the other's readings. Replacing both can provide peace of mind and prevent a similar repair in the near future.
