Ram ProMaster 1500 Crankshaft Position Sensor: A Complete Guide for 2014-2024
Experiencing stalling or a no-start condition in your ProMaster? Your crankshaft position sensor could be the culprit.
- A failing sensor can cause your ProMaster to stall at any time, which is a major safety hazard.
- The most common symptoms are a no-start condition, sudden stalling, and a Check Engine Light with code P0335.
- For reliability, choose a premium aftermarket brand like NGK/NTK, Delphi, or Standard Ignition (SMP).
- If you have a 3.0L Diesel engine, check with a dealer about the open recall for the crankshaft tone wheel.
Is Your ProMaster Stalling? Understanding Crankshaft Sensor Failure
A failing crankshaft position sensor in your 2014-2024 Ram ProMaster 1500 can cause serious and sudden problems. This sensor is the master clock for your engine. It tells the computer exactly where the pistons are in their rotation. When the sensor starts to fail, the computer gets bad information, leading to poor engine performance and, eventually, a van that won't run. Ignoring the signs can leave you stranded without warning.
Common Symptoms of a Bad Crankshaft Position Sensor
If your ProMaster's crankshaft sensor is failing, you'll likely notice one or more of these issues:
- Check Engine Light: A malfunctioning sensor will almost always trigger the check engine light. You'll likely see code P0335, 🎬 Watch this video to fix P0335 and related engine codes. but other codes like P0336 or P0300 (misfire) can also appear.
- Engine Stalls Unexpectedly: This is a dangerous symptom. The engine may cut out while you are driving, often without any warning.
- Engine Cranks but Won't Start: You'll hear the starter turning the engine over, but it will never fire up and run because the computer doesn't know when to create spark and fuel.
- Rough Idle and Engine Misfires: The van may shake or run unevenly when stopped. Incorrect timing information can cause engine misfires.
- Poor Acceleration: Your van may feel sluggish and lack power when you press the gas pedal.
Known Issues: Recalls & Service Bulletins
For 3.0L EcoDiesel Engines: There is a significant safety recall (NHTSA ID: 23V411, FCA Recall 66A) for some ProMaster models equipped with the 3.0L diesel engine. The issue involves the crankshaft sensor's tone wheel, which can fail and cause the engine to stall. The fix is a software update performed by a dealer.
For 3.6L Gas Engines: A Technical Service Bulletin (TSB #S2008000191) exists for some 2020 models that may show a Check Engine Light with codes P1300 (Crankshaft Position Learn Out of Range) and P0300 (Multiple Cylinder Misfire), which can be related to this sensor.
Choosing the Right Aftermarket Sensor
When your van is your business, you can't afford downtime. While Mopar is the original part, high-quality aftermarket brands offer reliable performance, often at a better price. Here’s how the brands break down:
Tier 1: Premium Aftermarket (Recommended)
- NGK (NTK), Delphi, Hitachi: These brands are often the original equipment manufacturers (OEM) for many car companies. They are known for producing sensors that meet or exceed factory specifications. For a critical part like a crankshaft sensor, choosing one of these brands is a smart investment in reliability.
- Standard Ignition (SMP): A long-standing and reputable brand in the aftermarket, offering high-quality components that are a trusted alternative to OEM.
Tier 2: Standard Aftermarket
- Dorman, Walker Products: These brands provide a good balance of value and quality. Dorman is known for engineering solutions that often match original designs and are widely available.
Tier 3: Value Options
- Crown Automotive, Holstein, Spectra, etc.: These brands offer a budget-friendly way to get your van running again. While functional, they may not offer the same long-term durability and precise calibration as premium brands.
Pro Tip: Given the safety risk of stalling, spending a little more on a premium aftermarket sensor from a brand like NGK/NTK or Delphi is highly recommended to ensure reliability and avoid replacing the part again soon.

Frequently Asked Questions (FAQ)
Where is the crankshaft position sensor on a ProMaster 1500?
For the common 3.6L V6 gas engine, the crankshaft position sensor is located on the side of the engine block, typically held in place by a single 10mm bolt. Access can be tight, but it is reachable from underneath or the side of the engine bay.
Can I replace this sensor myself?
Yes, this is a DIY-friendly job for someone with basic tools. The process involves disconnecting the battery, unplugging the electrical connector, and removing one bolt. 🎬 See this step-by-step walkthrough for replacing the sensor. However, after installation, a "crankshaft variation relearn" procedure using a professional-grade scan tool is recommended to ensure the computer is calibrated to the new sensor.
🎬 Watch: How to perform a crankshaft variation relearn procedure.What happens if I ignore a bad crankshaft sensor?
Ignoring a failing crankshaft sensor is not recommended. The problem will not fix itself and will likely get worse. It will progress from intermittent issues to a complete no-start condition, and carries the constant risk of the engine stalling while driving.
Is there a difference between the gas and diesel engine sensors?
Yes, the sensors and related issues are different. The 3.6L gas engine uses a specific sensor (like Mopar part #05149167AF). The 3.0L diesel engine has a different part and is subject to a recall related to its tone wheel, not just the sensor itself. Always verify your engine type before ordering.
