Ram 1500 Engine Camshaft Position Sensor Guide (2011-2019)
Having trouble with stalling or a rough idle? Your Ram's camshaft position sensor might be the culprit.
- A bad camshaft sensor on a Ram 1500 commonly causes stalling, rough idle, and no-start issues, often with a P0344 code.
- Before replacing the sensor, check your engine oil level, as low oil can trigger the same error code on HEMI engines.
- This is a simple, DIY-friendly repair that requires basic tools and usually takes less than 30 minutes.
- For this specific part, using an OEM Mopar sensor or a premium aftermarket brand like Delphi or NGK is strongly recommended to avoid repeat failures.
Is Your Ram 1500 Stalling or Running Rough?
A failing camshaft position sensor can cause a range of frustrating engine problems. Because this sensor is vital for engine timing, a bad signal can throw everything off. You might experience a rough idle, poor acceleration, or even have your truck stall unexpectedly. In some cases, the engine may crank but refuse to start at all. This guide will walk you through the common symptoms, how to choose the right aftermarket replacement, and what to expect for cost.
Symptoms of a Bad Camshaft Position Sensor
When this sensor starts to fail, your truck will let you know. Here are the most common signs:
- Check Engine Light: This is often the first warning. You'll likely see codes like P0340, P0344, P0341, P0342, or P0343.
- Engine Stalling: The engine may shut off unexpectedly while driving at low speeds or when stopped.
- Hard Starting or No Start: The truck may take longer than usual to start, or it might just crank without firing up.
- Rough Idle and Misfires: The engine may shake or vibrate noticeably when idling.
- Poor Acceleration: The truck may feel sluggish and lack power when you press the gas pedal.
- Reduced Fuel Economy: Incorrect timing can lead to inefficient fuel combustion, making you visit the gas station more often.
Known Issues & Important Notes for Ram 1500 Owners
The P0344 (Camshaft Position Sensor Circuit Intermittent) code is very common on these trucks. Before you replace the sensor, be aware of these other potential causes:
- Low Engine Oil: On the 5.7L HEMI, extremely low oil level can prevent the VVT system from working correctly at startup, which can trigger a P0344 code even if the sensor is good. Always check your oil level first.
- Wiring and Connectors: A loose or corroded connector, or damaged wiring, can mimic the symptoms of a failed sensor. Inspect the wiring harness leading to the sensor.
- Electrical Interference: In some cases, a failing ignition coil can create electrical "noise" that interferes with the camshaft sensor's signal, leading to an intermittent code.
Choosing the Right Aftermarket Sensor: Brand Tiers
When it comes to electronic sensors for your Ram, not all brands are created equal. Many owners and mechanics report issues with cheaper aftermarket sensors failing quickly or not working correctly out of the box. Using a quality part is key to avoiding having to do the job twice.
| Tier | Brands | Description |
|---|---|---|
| OEM / Premium Aftermarket | Mopar, Delphi, NGK, Standard Ignition (SMP) | Mopar is the original factory part and the safest bet for compatibility and longevity. Brands like Delphi, NGK, and Standard Ignition are often original equipment suppliers and are considered high-quality, reliable alternatives. |
| Mid-Grade Aftermarket | Walker Products, Crown Automotive, Hitachi | These brands offer a balance of value and quality. They are generally more reliable than economy options but may not have the same long-term durability as OEM or premium brands. |
| Economy / Value | Dorman, Holstein, True Tech, Encore, Global Parts | While attractively priced, these brands have a more mixed reputation for electronic sensors. They can be a budget-friendly option, but be aware that some owners report a higher chance of premature failure or out-of-box issues. |
Pro Tip: Given the number of forum posts from Ram owners who had to replace a cheap aftermarket sensor with a Mopar part to fix their issue, spending a little extra on an OEM or premium aftermarket sensor is highly recommended for this specific part.
Frequently Asked Questions (FAQ)
Where is the camshaft position sensor located on a 2011-2019 Ram 1500?
The location depends on your engine. On the 5.7L HEMI V8, it is located on the front of the engine, on the passenger side, near the top of the timing cover. On the 3.6L Pentastar V6, there are two sensors, one on the back of each cylinder head.
Can I replace this sensor myself?
Yes, this is a very DIY-friendly repair. For most engines, it involves removing a single bolt (usually 10mm) and an electrical connector. The job typically takes less than 30 minutes with basic hand tools.
Is there a recall on the camshaft position sensor?
There is no direct recall for the camshaft position sensor itself. However, there is a recall (NHTSA ID: 23V411) for the crankshaft position sensor on some 2014-2019 Ram 1500s with the 3.0L diesel engine. The fix involves a software update that allows the engine to use the camshaft sensor's signal as a backup if the crankshaft signal is lost, highlighting the importance of a functioning cam sensor. There are no such recalls for the 5.7L or 3.6L engines.
Do I need to do a "relearn" procedure after replacing the sensor?
Generally, no specific relearn procedure is required for the camshaft position sensor. After installing the new part, you should clear the diagnostic trouble codes with a scanner. The engine computer will recognize the new sensor's signal on its own. Some users report a crank relearn being beneficial after the change, but it is not typically required for the cam sensor.
