Dodge Caravan Engine Camshaft Position Sensor Guide (1990-2007)
Fix stalling, no-start, and check engine light issues on your Caravan by understanding this critical sensor.
- Verify your engine (3.3L/3.8L, 2.4L, or 3.0L) before ordering, as the part is different.
- Symptoms include stalling, no-start, rough idle, and a Check Engine Light with codes P0340 or P0344.
- For Chrysler products, using a premium aftermarket (Delphi, NGK, Standard) or OEM Mopar sensor is strongly advised to prevent repeat failures.
- On the common 3.3L/3.8L V6 engines, this is an easy DIY replacement located on the front timing cover.
Is Your Caravan's Camshaft Sensor Failing?
A bad camshaft position sensor can make your 1990-2007 Dodge Caravan run poorly or not at all. Because this sensor is so important for engine timing, a failure will cause noticeable problems. You should suspect a bad sensor if you experience one or more of the following issues.

The biggest mistake is ordering a sensor without knowing which engine your Caravan has. The 1990-2007 models used several different engines, and the sensor location and part design can vary significantly.
- 3.3L & 3.8L V6 Engines: These are the most common engines. They use a single camshaft position sensor located on the front of the engine, inserted into the timing chain cover. It is typically held in by a single 10mm bolt. 🎬 See this step-by-step replacement for the V6 3.8L engine
- 2.4L 4-Cylinder Engine: The sensor is also a distinct part on this engine, but in a different location than the V6 models.
- 3.0L V6 Engine: On these earlier, Mitsubishi-designed engines, the camshaft position sensing function is often built into the distributor assembly, not a separate, standalone sensor.
Pro Tip: Always verify your engine size before ordering. It is usually printed on a sticker under the hood or on the engine cover itself. This will save you time and prevent return shipping hassles.
Choosing the Right Aftermarket Sensor
When it comes to critical electronics on Chrysler-family vehicles, part quality matters a lot. While OEM Mopar sensors are the benchmark, several aftermarket brands offer a good balance of quality and value. Cheaper, unbranded sensors are known to cause persistent problems.
Brand Quality Tiers
- Tier 1: Premium Aftermarket (e.g., Delphi, NGK, Standard Ignition): These brands are often original equipment manufacturers for many car companies and are widely trusted by professional mechanics. They are engineered to meet or exceed OEM specifications and offer the best reliability outside of a genuine Mopar part.
- Tier 2: Reputable Aftermarket (e.g., Dorman, Walker Products, Holstein): These brands provide a more budget-friendly option and are generally reliable. While usually better than generic parts, quality can sometimes be inconsistent compared to premium brands.
- Tier 3: Economy / Store Brands: These are the lowest-priced options. While tempting, they carry the highest risk of premature failure, incorrect readings, or being dead-on-arrival. For a part that can cause stalling, it's often worth spending more for a reliable brand.
Aftermarket vs. OEM Cost
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket | $18.92 - $144.71 |
| New OEM (Mopar) | $95 - $165 |
| Shop Labor | $75 - $110 |
Frequently Asked Questions
Where is the camshaft sensor located on my Caravan?
For the popular 3.3L and 3.8L V6 engines, the sensor is on the front of the engine, pushed into the timing chain cover, often near the power steering pump. For the 3.0L V6, it is usually part of the distributor. Always consult a repair guide for your specific engine.
Can I replace this sensor myself?
Yes, for the 3.3L and 3.8L engines, this is a very DIY-friendly job. It's held by one bolt (usually 10mm) and an electrical connector. Access can be a little tight, but it typically takes less than an hour with basic hand tools.
What's the difference between a camshaft and a crankshaft sensor?
They are both vital timing sensors, but they measure different rotating parts. The camshaft sensor tracks the valve position in the top of the engine, while the crankshaft sensor tracks the piston position in the bottom of the engine. The computer compares both signals to ensure the engine is timed perfectly.
Do I need to reset the computer after replacement?
For this generation of Caravan, a special 'relearn' procedure is not usually required. After installing the new sensor, it's a good practice to clear the trouble codes using a scanner or by disconnecting the battery's negative terminal for about 15 minutes. The computer should then recognize the new sensor's signal on its own.

This is typically a three-wire, Hall-effect sensor that reads the camshaft's position via a reluctor wheel on the cam gear. The 3.3L and 3.8L engines use a single sensor. Some replacement sensors come with a paper spacer that is sheared off upon the first engine start to ensure proper air gap.
