Chrysler Cirrus and Sebring (2002-2010) Engine Crankshaft Position Sensor Guide
Having trouble with stalling or a no-start issue on your Chrysler? Your crankshaft sensor might be the problem.
- This guide applies to the 2002-2010 Chrysler Sebring, which was also sold as the Chrysler Cirrus in Mexico.
- Engine stalling is a critical symptom; do not drive the vehicle if this is happening.
- Choose a high-quality aftermarket brand like NGK or Standard Ignition for reliability, as cheap sensors are known to fail.
- Replacement difficulty varies greatly by engine; the 2.4L is much harder than the 2.7L.
A Note on Your Vehicle's Name
If you're looking for parts for a 2002-2010 Chrysler Cirrus, you're in the right place. In the United States and Canada, this car is known as the Chrysler Sebring. The Cirrus name was used for the same vehicle in the Mexican market during these years. All the information here applies to your vehicle, whether it's badged as a Cirrus or a Sebring.
Common Symptoms of a Failing Crankshaft Sensor
A crankshaft sensor usually doesn't fail quietly. Due to its location, it suffers from high heat and can be damaged by oil leaks, which are common causes of failure. When it starts to go bad, you will notice serious problems.
- Engine Won't Start: You might find the engine cranks over and over but never starts. This happens because the computer doesn't get the signal it needs to start the ignition and fuel delivery process.
- Check Engine Light: A failing crankshaft sensor will almost always trigger the check engine light. A common trouble code is P0335, which points directly to a problem in the sensor's circuit.
- Rough Running and Misfiring: Your car may idle poorly, shake, or feel down on power.
Choosing the Right Aftermarket Sensor
For a critical part like this, quality matters. While cheap options are available, many owners and mechanics report that low-cost sensors can fail quickly, forcing you to do the job all over again. Here’s a breakdown of the available aftermarket brands.
- Top Tier (Recommended): Brands like NGK (also sold as NTK) and Standard Ignition (SMP) are highly recommended. They are often the original equipment manufacturer for Chrysler and other carmakers. Choosing one of these brands gives you OEM-level quality and reliability without the dealership price tag.
- Value Tier: Brands like Walker Products and Motorad offer a more budget-friendly option. They can be a good choice if you need to save money, but their long-term durability may not match the top-tier brands.
- Other Brands: For a brand like True Tech, there is less information available from owner experiences. It may work fine, but it's a bigger gamble compared to the well-known brands.

Installation Tips
Replacing this sensor is a job a DIYer can handle, but the difficulty depends on your engine. The sensor is held in by a single 8mm or 10mm bolt.
- For the 2.7L V6 Engine: The sensor is located on the back of the engine. You will need to remove the air filter box to get access to it. This is the easier of the two common engines. 🎬 Watch: Step-by-step sensor replacement for the 2.7L V6 engine.
- For the 2.4L 4-Cylinder Engine: The job is more difficult. The sensor is located on the lower back side of the engine, and you must access it from underneath the car. You will likely need to support the engine with a jack and remove the front engine mount bracket to reach the sensor. 🎬 See how to access the sensor on 2.4L 4-cylinder models.
Frequently Asked Questions
Where is the crankshaft sensor located?
The location depends on your engine. On the 2.7L V6, it's on the upper rear of the engine block, accessible from the top after removing the airbox. On the 2.4L I4, it's on the lower rear of the engine block, accessible from underneath after removing an engine mount bracket or heat shield.
Is an OEM sensor really better than aftermarket for this part?
For critical sensors like this one, yes. An OEM Mopar part or a top-tier aftermarket brand like NGK/NTK or Standard Ignition is strongly recommended for reliability. Cheaper sensors have a higher rate of failure, which could leave you stranded again.
What does the code P0335 mean?
P0335 stands for "Crankshaft Position Sensor 'A' Circuit Malfunction." It means the engine's computer has lost the signal from the crankshaft sensor or the signal is incorrect. This is the most common code associated with a failed sensor.
