Chrysler Town & Country Engine Camshaft Position Sensor: A Comprehensive Guide (1990-2011)
Experiencing stalling or a check engine light in your Town & Country? Your camshaft position sensor might be the culprit.
- Symptoms include stalling, no-start, rough idle, and a Check Engine Light with codes P0340 or P0344.
- The issue might be the wiring or connector, not just the sensor. Inspect for oil leaks or damage first.
- For reliability, choose an OEM (Mopar) or premium aftermarket brand like Delphi or Hitachi.
- A 'relearn' procedure with a scan tool may be required after replacement, especially on later models.
Understanding Camshaft Position Sensor Failure in Your Town & Country
A failing camshaft position sensor is a common issue on many vehicles, including the 1990-2011 Chrysler Town & Country. This sensor lives in a harsh environment of heat and vibration, and can also be damaged by oil leaks. When it starts to fail, it sends weak or incorrect signals to the engine computer, leading to a range of noticeable problems. Ignoring these symptoms can leave you stranded, as a completely failed sensor will prevent the engine from starting.
Is it the Sensor or Something Else?
Before replacing the sensor, it's wise to check for other potential issues. The problem codes associated with this sensor, like P0340 and P0344, often point to a circuit malfunction. This means the issue could be the sensor itself, damaged wiring, a loose or corroded connector, or in rare cases, the engine computer (PCM). Always inspect the wiring and connector for oil contamination, corrosion, or damage before buying a new part. A Reddit user noted that after replacing a sensor, the code returned with an "intermittent circuit" message, highlighting the importance of checking the entire circuit.
Warning: Crankshaft vs. Camshaft Sensor
The camshaft position sensor works with the crankshaft position sensor. Sometimes, a problem with the crankshaft sensor can trigger a code for the camshaft sensor. It's important to diagnose the issue correctly. If you have codes for both sensors, they may need to be diagnosed as a pair.
Choosing the Right Aftermarket Sensor
When it comes to critical engine sensors, quality matters. While many budget-friendly aftermarket options are available, forum discussions and mechanic advice often recommend sticking with higher-quality brands to avoid premature failure and frustrating repeat repairs.
Brand Quality Tiers
- OEM/Premium Aftermarket (Highest Quality): Mopar (the original Chrysler part), Delphi, and Hitachi are often considered top-tier choices. These brands typically have direct experience as original equipment suppliers and their parts are built to meet or exceed factory specifications. They are the most reliable choice for a long-term fix.
- Reputable Aftermarket (Good Quality): Brands like Standard Ignition (SMP), NGK/NTK, and Dorman offer a good balance of quality and price. They are well-known in the aftermarket and often provide reliable parts with good warranties.
- Value-Oriented (Use with Caution): Other brands may offer significant cost savings, but their long-term reliability can be inconsistent for critical sensors. While they may work, there is a higher risk of early failure compared to premium brands.
Pro Tip: The Relearn Procedure
For some Town & Country models, especially later years with the 3.6L engine, a "Cam/Crank Variation Relearn" procedure may be necessary after replacing the sensor. This procedure, done with a capable OBD-II scan tool, calibrates the new sensor to the engine computer. Failing to do this can result in continued running issues or a persistent check engine light.
Cost to Replace a Town & Country Camshaft Position Sensor
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket Part | $15.95 - $189.24 |
| New OEM (Mopar) Part | $50 - $200+ |
| Shop Labor | $100 - $200 |
| Total Professional Replacement | $150 - $400+ |
Costs are estimates and can vary based on your vehicle's engine, your location, and the specific part brand chosen. Labor costs are typically around 1 hour.
Frequently Asked Questions (FAQ)
Where is the camshaft position sensor located on my Town & Country?
The location depends on your engine:
- 3.3L & 3.8L V6 Engines: The sensor is typically located on the front of the engine, near the thermostat housing and power steering reservoir. You may need to remove the air filter housing for access.
- 4.0L V6 Engines: The location is similar to the 3.3L/3.8L engines, on the front of the engine.
- 3.6L Pentastar V6 Engines (2011): These engines have two camshaft position sensors. Bank 1 (rear) is on the driver's side of the rear cylinder head. Bank 2 (front) is on the passenger side of the front cylinder head.
Are there any recalls for this part?
No. While Chrysler has issued recalls for camshaft or crankshaft sensor issues on other models and years, there are no widespread, active recalls specifically for the camshaft position sensor on the 1990-2011 Chrysler Town & Country. Always check for recalls on your specific vehicle using its VIN on the NHTSA website.
What is a TSB and are there any for this sensor?
A Technical Service Bulletin (TSB) is a notice from the manufacturer to dealers about a common problem and its fix. TSB 18-054-14 was issued for some 2014 models (outside this guide's range, but relevant to the 3.6L engine) for an intermittent long crank time. It involved inspecting the sensor's serial number and potentially replacing it, followed by a relearn procedure. This indicates that even the manufacturer has identified batches of faulty sensors, making brand choice important.
Can I replace this sensor myself?
Yes, for most owners with basic tools, this is a DIY-friendly job. The sensor is usually held in by a single bolt (often a 10mm or a Torx screw) and has a single electrical connector. The main challenge is accessing it, which may require removing the engine cover or air filter box. Always disconnect the negative battery terminal before starting work.
