Ram 1500 Engine Crankshaft Position Sensor Guide (2011-2019)
Having starting trouble or a rough idle? Your crankshaft position sensor might be the problem.
- Symptoms include stalling, no-start, rough idle, and a P0335 or P0336 check engine code.
- If you own a 2014-2019 Ram 1500 with a 3.0L EcoDiesel, check for an open recall related to the sensor's tone wheel.
- For reliability, choose an OEM Mopar sensor or a high-quality aftermarket brand like NGK/NTK or Delphi.
- Replacement is a simple, one-bolt job, but access is tight; it's located on the passenger side of the engine near the transmission.
Is Your Ram 1500 Stalling or Hard to Start?
A failing crankshaft position sensor can cause a range of frustrating issues for 2011-2019 Ram 1500 owners. This sensor is the main source of timing information for your engine's computer. When it starts to go bad, the signals it sends can become weak or erratic, leading to noticeable performance problems. It's a common failure point on many vehicles as they age, and Ram trucks are no exception.
Known Issues & Recalls
There is a significant safety recall (NHTSA 20V-475, expanded by 66A) for some 2014-2019 Ram 1500 models equipped with the 3.0L EcoDiesel engine. The issue involves the crankshaft position sensor's tone wheel, which can come apart and cause the engine to stall without warning. The fix is a software update from a dealer to help the truck keep running using the camshaft sensor if the crankshaft signal is lost. If you have a 3.0L diesel, it is critical to check if this recall applies to your truck.
Choosing the Right Aftermarket Crankshaft Sensor
When it comes to engine sensors for your Ram, quality matters. While the original Mopar part is always an option, many aftermarket brands offer a good balance of quality and price. However, owner experiences suggest that not all aftermarket sensors are created equal.
Brand Quality Tiers
- Top Tier (OEM or Equivalent): Mopar is the factory part. Many Ram owners and mechanics strongly recommend sticking with Mopar for critical sensors to avoid compatibility issues. Brands like NGK/NTK and Delphi are often considered OEM-equivalent suppliers and have a strong reputation among truck owners for reliability. Hitachi is another brand often associated with OEM quality.
- Mid-Tier (Reputable Aftermarket): Brands like Standard Motor Products (SMP) and Walker Products are well-known in the aftermarket and can be a reliable choice. Dorman offers a wide range of parts, but their quality can sometimes be inconsistent according to forum discussions.
- Economy Tier (Budget-Friendly): Cheaper, lesser-known brands can be a gamble. While they might work initially, some owners report premature failure or performance issues, leading to replacing the part again. For a part that can leave you stranded, saving a few dollars on an unproven brand might not be worth the risk.
Pro Tip: Many experienced Ram owners recommend replacing the camshaft position sensor at the same time as the crankshaft position sensor. They are related in function, and if one has failed due to age and heat, the other may not be far behind.

Frequently Asked Questions
Where is the crankshaft position sensor located on a 2011-2019 Ram 1500?
The sensor is typically located on the passenger side of the engine block, down low where the engine meets the transmission bell housing. You will likely need to access it from underneath the truck. 🎬 See how to remove the sensor on a 5.7 Hemi. It is held in by a single bolt.
🎬 Watch: Step-by-step crankshaft sensor replacement for 3.6L V6 engines.Can I replace this sensor myself?
Yes, this is a DIY-feasible job for someone with basic tools. The main challenge is access, as the sensor is in a tight spot. You'll need a ratchet, extension, and a 10mm socket. After replacement, some sources recommend performing a "crankshaft position sensor relearn" procedure with a capable scan tool to ensure proper communication with the engine computer.
What are the most common fault codes for a bad crank sensor?
The most common trouble codes are P0335 (Crankshaft Position Sensor 'A' Circuit Malfunction) and P0336 (Crankshaft Position Sensor 'A' Circuit Range/Performance). P0335 usually means there is no signal, while P0336 suggests the signal is intermittent or incorrect.
🎬 Watch this repair guide for fixing engine code P0335.Should I buy the cheapest aftermarket sensor?
It's generally not recommended. Many Ram owners have reported issues with very cheap, no-name sensors failing quickly or not working correctly out of the box, causing stalling and no-start problems. Sticking with a reputable brand like Mopar, NGK/NTK, or Delphi is a safer bet.
