Engine Crankshaft Position Sensor for the 2005-2008 Dodge Magnum
Understanding why your Magnum stalls and how to choose the right crankshaft position sensor to fix it.
- Sudden engine stalling, especially when warm, is the number one sign of a failing crankshaft sensor in a Dodge Magnum.
- Chrysler vehicles are sensitive to electronics; choosing a quality aftermarket brand like NGK/NTK or Delphi is highly recommended over budget options.
- On V8 HEMI models, the starter motor must be removed to access the sensor, making the replacement more complex than on V6 models.
- Do not drive with these symptoms. A sudden stall can lead to a loss of vehicle control and is a serious safety risk.
Is a Failing Crankshaft Sensor Causing Your Magnum to Stall?
If you own a 2005-2008 Dodge Magnum, one of the most common and frustrating issues you might face is the engine suddenly stalling. This often happens when the engine is warm, like when you're sitting at a stoplight or driving at low speeds. While several things can cause stalling, a failing crankshaft position sensor is a very common culprit for these symptoms. This guide will walk you through the symptoms, how to choose the right aftermarket replacement, and what to expect from the repair.
Symptoms of a Bad Crankshaft Position Sensor
A bad crankshaft sensor doesn't always fail completely at first. It might start with intermittent problems that get worse over time. Here’s what to look for:
- Engine Stalling: The most reported issue is the engine stalling unexpectedly, especially when warm. It may start back up after it cools down.
- Trouble Starting: The engine may crank for a long time before it starts, or it might not start at all.
- Check Engine Light: A failing sensor will often trigger the Check Engine Light and store a diagnostic trouble code, most commonly P0335 or P0339. 🎬 Watch this video to diagnose P0335 circuit codes on your Magnum.
- Rough Idle and Misfires: Your engine may run rough, vibrate, or misfire because the computer can't time the spark and fuel correctly.
- Poor Acceleration: You might notice a lack of power or hesitation when you press the gas pedal.
- Decreased Fuel Economy: Inefficient engine timing caused by a bad sensor can lead to worse gas mileage.
Safety Warning: Sudden Stalling is Dangerous
An engine that stalls while you are driving is a serious safety hazard. It can cause a loss of power steering and power brakes, making the vehicle difficult to control. If you are experiencing sudden stalling, it is highly recommended to get the vehicle inspected and repaired as soon as possible.
Choosing the Right Aftermarket Sensor: OEM vs. Aftermarket
When it comes to electronic sensors on Chrysler and Dodge vehicles from this era, the choice between OEM (Original Equipment Manufacturer) and aftermarket parts is important. Many owners and mechanics report that these engines can be very sensitive to the quality of electronic parts.
While Mopar (the OEM parts brand for Dodge) is always a safe bet, some high-quality aftermarket brands are known to be reliable alternatives. Cheaper, no-name sensors have a higher risk of being dead-on-arrival or failing prematurely.
Aftermarket Brand Tiers for Your Magnum
- Tier 1: OEM-Equivalent Brands: Brands like NGK (also sold as NTK) and Delphi are often considered OEM suppliers or have a reputation for producing parts that meet or exceed original specifications. These are your best bet for a reliable aftermarket sensor that is less expensive than the dealer part.
- Tier 2: Reputable Aftermarket Brands: Brands like Standard Ignition (SMP), Hitachi, and Walker Products are well-known in the industry and generally offer a good balance of quality and price. They are a solid choice for most repairs.
- Tier 3: Budget-Friendly Options: Brands like Dorman and other lower-priced options can be a gamble. While they may work, forum discussions show mixed results, with some owners reporting quick failures. These are best used if budget is the primary concern and you understand the potential risk.
Pro Tip: Check the Part Before Installing
No matter which brand you choose, compare the new sensor to the old one before installation. Make sure the mounting points, connector shape, and sensor length are identical. This can save you the headache of installing a part that doesn't fit.

Installation Overview
Replacing the crankshaft sensor is a manageable DIY job for most home mechanics. The difficulty varies slightly depending on your engine.
- For V6 Engines (2.7L & 3.5L): The sensor is located on the passenger side of the engine, near the back where the engine meets the transmission. It is held in by a single 10mm bolt. Access can be tight, but it is reachable from underneath the car. 🎬 Watch a step-by-step replacement guide for the V6 engine models.
- For V8 HEMI Engines (5.7L & 6.1L): The sensor is in a similar location on the passenger side, but it is blocked by the starter motor. You must disconnect the battery, then remove the starter to gain access. 🎬 See this walkthrough for replacing the sensor on HEMI V8 engines. This makes the job more involved. The sensor itself is held by one 10mm bolt.
Frequently Asked Questions (FAQ)
Is there a recall on the crankshaft position sensor for the Dodge Magnum?
No, there are no specific recalls for the crankshaft position sensor itself on the 2005-2008 Dodge Magnum. There was a recall for some other Chrysler vehicles related to a tone wheel that works with the sensor, but it did not apply to the Magnum. There are several other unrelated recalls for this vehicle, mostly for airbags and ignition switches.
What is TSB 18-033-11 for the P0339 code?
Dodge issued a Technical Service Bulletin (TSB) for an issue where the code P0339 (Crankshaft Position Sensor Intermittent) could be set. The fix involved adding a special shim to the sensor. This TSB only applies if this specific code is present and other potential causes have been ruled out.
Can I drive my Magnum with a bad crankshaft sensor?
It is not recommended. A failing sensor can cause the engine to stall at any time, including at high speeds or in traffic, which is extremely dangerous. If the sensor fails completely, the engine will not start at all, leaving you stranded.
Do I need to perform a relearn procedure after replacing the sensor?
For most simple replacements, a relearn procedure is not required. The engine computer will adapt to the new sensor after a few drive cycles. However, some service manuals mention a "CKP pattern learn" procedure that can be done with a professional scan tool to optimize performance immediately. If you clear the trouble codes and the car runs well, you are likely fine.
