Mercedes-Benz Sprinter 2500 Crankshaft Position Sensor Guide (2010-2018)
Solve stalling, no-start, and poor performance issues by understanding this critical engine sensor in your Sprinter van.
- A failing crankshaft sensor is a critical issue that can cause your Sprinter to stall while driving.
- The most common symptom is the engine stalling when hot and refusing to restart until it has cooled down.
- Due to very tight access, replacement is a difficult job; expect shop labor costs of $100-$180.
- For this part, it is highly recommended to use an OEM or a top-tier aftermarket brand like Delphi or Hella for reliability.
Is Your Sprinter Stalling or Not Starting? It Could Be the Crankshaft Sensor
If your 2010-2018 Sprinter 2500 suddenly stalls, especially when the engine is hot, or if it cranks but refuses to start, a failing crankshaft position sensor is a very common cause. This sensor provides the engine's computer with the essential information it needs to run. When it fails, the computer is flying blind, leading to serious and potentially dangerous driving issues. 🎬 Watch: 9 common symptoms of a bad crankshaft sensor Because this part can cause your engine to shut off without warning, it's a problem you need to address immediately.
Critical Part Warning
A complete failure of the crankshaft position sensor will cause the engine to stall while driving and will prevent it from restarting. This is a significant safety hazard. Do not continue to drive a vehicle with symptoms of a failing crankshaft sensor.
Choosing the Right Aftermarket Sensor
For a critical sensor like this, part quality matters. While an OEM sensor from a Mercedes-Benz dealer is an option, high-quality aftermarket parts can offer the same performance for less money. However, owner experiences show that the cheapest, unbranded sensors are unreliable and should be avoided. They are known to fail quickly or not work at all right out of the box. It's best to choose a part from a well-regarded manufacturer.
Aftermarket Brand Tiers for Your Sprinter
- Top Tier (OEM Quality): Brands like Delphi and Hella are often original equipment suppliers to many European car brands. They are engineered to meet or exceed the original factory specifications and are a reliable choice for longevity. Forum users frequently recommend using OEM or OEM-supplier brands like Bosch for this specific repair.
- Mid-Tier (Reputable Aftermarket): Brands such as Standard Ignition (SMP), NGK, and Spectra have a long history of producing dependable aftermarket components. These offer a good balance of price and quality and are a solid choice for most owners.
- Economy Tier: Brands like Dorman, Vemo, and Walker Products provide a budget-friendly option. While they can get your van back on the road, they may not have the same long-term durability as higher-tier options for this specific part.
Pro Tip: Check the Part Before Installing
Some Sprinter owners have reported that certain aftermarket sensors are difficult to install because of slight differences in size. Before you begin the difficult process of replacement, compare the new sensor to the old one to ensure the dimensions are identical.
Cost to Replace the Crankshaft Position Sensor

Frequently Asked Questions (FAQ)
Where is the crankshaft position sensor located on a 2010-2018 Sprinter 2500?
The sensor is located on the driver's side of the engine, mounted to the transmission bell housing, just above the starter. 🎬 See this video for the exact sensor location and replacement Access is from underneath the vehicle, and the space is very tight, making it a challenging part to reach.
Is this a difficult DIY job?
Yes, this is considered a difficult job for a DIYer, not because it's complex, but because of the terrible access. It requires an E8 external Torx socket, a small ratchet, and long extensions. Many owners report frustration with removing the electrical connector and the sensor itself in such a cramped space. If you have large hands or limited patience, it may be best to leave this job to a professional.

There are no specific recalls for the crankshaft position sensor on the 2010-2018 Sprinter 2500. However, there was a safety recall (NHTSA ID: 08V-006) for this exact part on earlier 2007-2008 models that used the same V6 diesel engine family (OM642). The recall was for sensors that could fail and cause the engine to stall without warning.
Do I need to reset the computer after replacing the sensor?
