Engine Camshaft Position Sensor Guide for the 1995-2001 Chrysler Cirrus
Solve common stalling, rough idle, and no-start problems in your Cirrus by understanding this critical engine sensor.
- A failing camshaft sensor is a top cause for stalling, no-starts, and rough running in the 1995-2001 Cirrus.
- The most common trouble code associated with this failure is P0340.
- For reliable performance, choose a premium aftermarket brand like Delphi, NGK, or Standard Ignition (SMP) over the cheapest options.
- Before replacing the sensor, always inspect the wiring and connector for damage, as this can cause the same symptoms.
Is Your Cirrus Stalling or Hard to Start? It Could Be the Camshaft Sensor.
If your 1995-2001 Chrysler Cirrus is suddenly stalling, running rough, or won't start at all, a failing camshaft position sensor is a very common cause. This sensor is known to fail and can leave you stranded. When it malfunctions, it often triggers the Check Engine Light and stores a specific trouble code, most commonly P0340, which points to a problem in the sensor's circuit.

When it comes to electronic sensors on Chrysler vehicles of this era, part quality matters. While many budget-friendly options are available, owner and mechanic experiences suggest that some low-cost aftermarket sensors can fail quickly or be dead-on-arrival. For a critical part like this, it's often better to choose a higher-quality replacement to avoid doing the job twice.
Brand Quality Tiers
- Premium Aftermarket (Recommended): Brands like Delphi, NGK/NTK, and Standard Ignition (SMP) are well-regarded for their quality and reliability, often meeting or exceeding original equipment (OE) standards. They are tested to ensure accurate readings and durability, making them a solid choice for a lasting repair.
- OEM Mopar: The original factory part is always a safe bet, but it will be the most expensive option. For older vehicles, a premium aftermarket part often provides the same reliability for less money.
- Value-Oriented Aftermarket: Brands like Dorman, Holstein, and various store brands offer a more affordable price point. While they can be a good budget solution, be aware that the consistency might not be as high as premium brands. If you choose a value brand, be sure it comes with a good warranty.
Pro Tip: On many Chrysler engines from this period, the camshaft and crankshaft position sensors work together. If you are replacing one due to age or high mileage, it's often a good idea to replace the other at the same time, as they tend to have similar lifespans.
Installation Overview
Replacing the camshaft position sensor on a 1995-2001 Cirrus is a straightforward job for a DIYer with basic tools. The location varies depending on your engine:
- For the 2.4L 4-Cylinder Engine: The sensor is typically located on the cylinder head, near the timing belt cover on the driver's side of the engine.
- For the 2.5L V6 Engine: The sensor is located inside the distributor. This makes replacement more involved, as the distributor cap, rotor, and potentially the entire distributor housing may need to be removed to access it.
The job usually involves disconnecting the negative battery terminal, unplugging the electrical connector, and removing a single bolt holding the sensor in place. Always apply a small amount of clean engine oil to the new sensor's O-ring before installation to ensure a good seal and prevent damage.
🎬 See a step-by-step guide on replacing the camshaft sensor.Common Mistake: The P0340 code indicates a problem in the sensor's circuit, not necessarily the sensor itself. Before replacing the sensor, always inspect the wiring and connector for damage, corrosion, or loose pins. A damaged wire or bad connection can cause the same symptoms as a failed sensor.
Cost of Replacing the Camshaft Position Sensor
| Part or Service | Estimated Cost |
|---|---|
| New Aftermarket Sensor | $17 - $127 |
| Shop Labor | $140 - $200 |
| Total Professional Replacement | $160 - $330+ |
Frequently Asked Questions
Where is the camshaft position sensor located on my Cirrus?
On the 2.4L 4-cylinder engine, it's on the side of the cylinder head. On the 2.5L V6, it is housed inside the distributor assembly.
What does the P0340 trouble code mean?
P0340 means the engine's computer has detected a malfunction in the camshaft position sensor's electrical circuit. This could be a bad sensor, damaged wiring, a poor connection, or in rare cases, an issue with the computer itself.
Can I just clean my old sensor?
No. The camshaft position sensor is a sealed electronic component (a Hall effect sensor). Failure is typically due to internal electronic breakdown, not dirt. Cleaning the outside will not fix a failed sensor.
Why do some people say to only use Mopar sensors?
Chrysler vehicles of this era can be sensitive to the quality of electronic sensors. Some lower-quality aftermarket sensors may not have the same magnetic strength or precise electronic components as the original, leading to continued problems. 🎬 Watch a comparison of OEM vs aftermarket Chrysler sensors. While Mopar is a guaranteed fit, high-quality aftermarket brands like Delphi or NGK are widely considered reliable alternatives.
