Chrysler Cirrus Engine Camshaft Position Sensor Guide (2002-2010)
Diagnosing and fixing stalling, rough idle, and no-start problems in your Chrysler Cirrus.
- This guide applies to the 2002-2010 Cirrus (Mexico), which is the same as the US-market Sebring/Stratus.
- Key symptoms are stalling, no-start conditions, and a Check Engine Light with code P0340 or P0344.
- Replacement is simple for DIYers and requires basic tools, often taking less than 30 minutes.
- Consider using an OEM Mopar sensor or a high-quality aftermarket brand like NGK or Standard Ignition for best results.
A Note on Vehicle Models
This guide is for the 2002-2010 Chrysler Cirrus, a model sold primarily in the Mexican market. These vehicles are mechanically the same as the Chrysler Sebring and Dodge Stratus models sold in the United States and Canada during the same years. Information and parts for the 2002-2010 Sebring/Stratus are directly applicable to your Cirrus.
Symptoms of a Failing Camshaft Position Sensor
A bad camshaft position sensor can make your car unreliable. The most common sign is the Check Engine Light turning on, often with error code P0340 or P0344 stored in the computer. You might also experience:
- Engine Stalling: The engine may suddenly shut off while you are driving, which can be a serious safety issue.
- Hard Starting or No Start: The car may take a long time to start, or it might just crank without ever firing up.
- Rough Idle and Misfires: The engine may run poorly, shake, or vibrate when stopped.
- Poor Acceleration: You may notice a lack of power when you press the gas pedal.
Choosing the Right Aftermarket Sensor
When replacing the camshaft sensor, you have a choice between OEM (Original Equipment Manufacturer) from Mopar and various aftermarket brands. For Chrysler electronics, this choice can be important.
A Mechanic's Advice on OEM vs. Aftermarket: Some experienced technicians strongly recommend using only OEM Mopar sensors on Chrysler vehicles, especially for critical electronics like the cam and crank sensors. They argue that aftermarket sensors can sometimes fail prematurely or not communicate perfectly with the Chrysler PCM, causing the problem to return. However, other owners have used quality aftermarket parts without issue and saved money. If your budget allows, an OEM sensor is the safest bet. If you choose aftermarket, stick to reputable brands.
Aftermarket Brand Tiers
- Tier 1 (High Quality): Brands like NGK (also known as NTK for sensors) and Standard Ignition (SMP) are well-regarded in the industry for producing reliable parts that often meet or exceed original specifications. These are a solid choice if you are opting for an aftermarket part.
- Tier 2 (Good Quality): Walker Products is a known manufacturer that produces a wide range of sensors. They emphasize quality control and testing to ensure their parts perform correctly. This brand offers a good balance of price and quality.
- Tier 3 (Value): Brands like True Tech fall into the value category. While they are the most affordable, their long-term reliability may not match that of the higher-tier brands. They can be a solution for a tight budget, but be aware of the potential for a shorter lifespan.
Typical Replacement Costs
The cost to replace the camshaft position sensor depends on whether you do it yourself or have a shop perform the work. The part itself is not expensive.

| New Aftermarket Part | $18.83 - $54.09 |
| New OEM (Mopar) Part | $64 - $141 |
| Shop Labor | $49 - $140 |

Frequently Asked Questions
Where is the camshaft position sensor located?
On the popular 2.7L V6 engine, the camshaft position sensor is located on the top of the driver's side cylinder head. On the 2.4L 4-cylinder, it is typically found at the rear of the cylinder head. It is usually black plastic and held in place by a single bolt.
Can I replace this sensor myself?
Yes, this is a very DIY-friendly repair for most home mechanics. The sensor is usually easy to access and requires only basic tools, like a 10mm or 13mm wrench and a screwdriver. The entire job can often be completed in under 30 minutes.
What happens if I don't replace a bad camshaft sensor?
Ignoring a failing camshaft sensor can leave you stranded. The engine stalling can happen at any time, which is a significant safety risk in traffic. Continuing to drive may also lead to poor fuel economy and could potentially damage other components like the catalytic converter over time.
My check engine light is on for code P0340. Is it definitely the sensor?
Code P0340 points to a malfunction in the camshaft position sensor circuit. While a failed sensor is the most common cause, the problem could also be damaged wiring, a loose connection, or in rare cases, an issue with the engine's timing components or the PCM. Always inspect the wiring and connector for damage or oil contamination before replacing the part.
