Dodge Grand Caravan Camshaft Position Sensor Guide (2012-2020)
Is your Grand Caravan running rough, stalling, or showing a check engine light? A bad camshaft position sensor could be the culprit.
- A failing sensor causes stalling, hard starts, and poor acceleration, with codes like P0340 and P0344.
- For Dodge vehicles, using an OEM (Mopar) or OEM-equivalent (NGK/NTK) sensor is strongly recommended to avoid repeat failures.
- The rear sensor is difficult to access and requires removing the upper intake manifold, increasing labor time and cost.
- A "cam/crank relearn" procedure with a scan tool is recommended after replacement for best results.
Symptoms of a Failing Camshaft Sensor in a Grand Caravan
A bad camshaft position sensor won't typically leave you stranded immediately, but the symptoms will get worse over time. The 3.6L engine is sensitive to sensor data, so you'll likely notice problems quickly. The most common sign is the Check Engine Light turning on.
Other common symptoms include:
- Difficulty Starting: The engine may crank for a long time before it finally starts, or it might not start at all on the first try.
- Engine Stalling: The engine may suddenly shut off while you are driving or idling at a stoplight.
- Rough Idle: Your van may shake or shudder when it's in park or stopped.
- Poor Acceleration: You might feel a hesitation or lack of power when you press the gas pedal.
- Reduced Fuel Economy: Incorrect timing from a bad sensor can cause the engine to use more fuel than normal.
Is It the Sensor or Something Else?
On the 3.6L Pentastar engine, camshaft sensor error codes (like P0340 or P0344) can sometimes be a symptom of a more serious internal engine issue, such as failing cam phasers or rocker arms. If you replace a sensor and the code returns quickly, especially if you also hear a ticking or rattling noise on startup, it is wise to have a professional mechanic diagnose the engine's valvetrain.
Choosing the Right Aftermarket Sensor: Brand Quality Matters
When it comes to electronic sensors for Chrysler and Dodge vehicles, not all aftermarket brands are created equal. Many owners and mechanics report that using cheap, low-quality sensors often leads to the same problems returning shortly after the repair. For a critical part like this, investing in a quality brand is recommended to avoid doing the job twice.
Here’s a breakdown of available brands, tiered by general quality and reputation among Dodge owners:
- OEM / Premium Aftermarket (Highest Quality): Mopar is the original factory part and offers the best guarantee of compatibility. NGK (also sold as NTK) is widely considered to be the manufacturer of the original Mopar sensor, making it an excellent and often more affordable alternative.
- Reputable Aftermarket (Good Quality): Brands like Delphi, Hitachi, and Standard Ignition (Standard Motor Products) have a long history of producing reliable electronic components and are a solid choice for a balance of price and quality.
- Economy / Value (Use with Caution): Brands like Dorman, Crown Automotive, and other lesser-known names offer the lowest price. While they can be a budget-friendly option, forum discussions suggest a higher rate of failure or out-of-the-box issues with these sensors on Chrysler/Dodge vehicles.
Pro Tip: Replace in Pairs?
Your Grand Caravan has two camshaft position sensors. If one has failed due to age and high mileage, the other may not be far behind. While not strictly necessary, if you are already removing the intake manifold to access the difficult rear sensor, replacing both at the same time can save you from having to do the same labor-intensive job again in the near future.
Cost of Replacing a Dodge Grand Caravan Camshaft Position Sensor
| Part Type | Typical Cost |
|---|---|
| New Aftermarket Sensor | $32 - $131 |
| New OEM (Mopar) Sensor | $70 - $150 |
| Shop Labor | $100 - $250 |
Cost estimates are approximate and can vary by location and supplier. Labor costs can be higher if the more difficult rear sensor needs replacement, as this requires removing the upper intake manifold. 🎬 Watch: How to safely remove the intake manifold plenum
Frequently Asked Questions (FAQ)
Where are the camshaft position sensors located on a 2012-2020 Grand Caravan?
The 3.6L engine has two sensors. One is on the front cylinder head (Bank 2) and is relatively easy to see and access. 🎬 See how to access and swap the front sensor The other is on the rear cylinder head near the firewall (Bank 1) and is much harder to reach, typically requiring the removal of the upper intake manifold.
What is a "cam/crank relearn" and is it necessary?
A cam/crank relearn is a procedure done with a professional scan tool that allows the engine computer (PCM) to learn the new sensor's position relative to the crankshaft. A Technical Service Bulletin (TSB 18-054-14) for some models recommends this procedure after replacement. While the van may run without it, performing the relearn is recommended for optimal performance and to prevent future codes.
Are there any recalls for this part?
No, there are no active recalls from the NHTSA for the camshaft position sensor itself on the 2012-2020 Dodge Grand Caravan. There was a recall for the sensor's wiring harness on some other 2016 Dodge models, but the Grand Caravan was not included.
Can I replace this sensor myself?
Replacing the front sensor is a fairly simple DIY job for someone with basic tools. However, replacing the rear sensor is more involved because you must remove the upper intake manifold. This is more of an intermediate-level task. If you are not comfortable with that, it's best to leave it to a professional.
