Is your 2006 Dodge Magnum or Chrysler 300 3.5L AWD running poorly, stalling, or refusing to start? A failing Engine Control Module (ECM) is often the culprit. As the central computer of your vehicle’s engine, a faulty ECM can cause a cascade of frustrating and difficult-to-diagnose issues. This direct-replacement engine computer, part number 5094593ab, is the definitive solution to restore your vehicle’s performance, reliability, and efficiency. It arrives at your door fully programmed to your vehicle’s specific VIN and mileage, making installation a straightforward, plug-and-play process without the need for an expensive trip to the dealership.
Is Your Mopar Showing Signs of a Faulty ECM?
A failing engine computer can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following symptoms, it’s a strong indicator that your ECM may need replacement:
- ✔ Check Engine Light: A persistent check engine light, especially with communication-related fault codes (U-codes) or multiple random sensor codes, points towards the central computer.
- ✔ No-Start or Hard-Start Condition: The engine cranks but refuses to start, or takes an unusually long time to fire up, often due to the ECM failing to properly manage fuel and spark.
- ✔ Engine Stalling or Misfiring: Your vehicle may stall unexpectedly while driving or at idle. You might also notice rough idling, hesitation during acceleration, or engine misfires.
- ✔ Poor Fuel Economy: A sudden and unexplained drop in gas mileage can be caused by the ECM providing incorrect fuel mixture calculations.
- ✔ Erratic Transmission Behavior: The ECM works closely with the transmission controller. A failing ECM can sometimes cause harsh shifting or other transmission-related symptoms.
- ✔ Complete Loss of Communication: In severe cases, a diagnostic scan tool may be unable to communicate with the engine computer, confirming a critical failure.
From the Diagnostic Bay
We had a 2006 Magnum 3.5L AWD come into the shop that was a real head-scratcher. The owner had already replaced the crankshaft sensor, camshaft sensor, and a full set of spark plugs chasing an intermittent stalling and no-start issue. The codes were all over the place—one day it was a sensor circuit code, the next it was a random misfire. The tell-tale sign was that after clearing the codes, a completely different set would appear after the next stall. This inconsistency is a classic symptom of a failing processor in the ECM. The computer itself was creating the phantom codes. We installed a VIN-programmed 2006 Magnum Engine Computer, and the car fired up instantly and ran perfectly. The customer could have saved hundreds of dollars and weeks of frustration by addressing the core problem first.
The Plug-and-Play Solution for Your 2006 Magnum Engine Computer
Don’t let a complex electrical diagnosis keep you off the road. We simplify the repair process. When you order this module, we handle the complex programming for you. By providing your 17-digit Vehicle Identification Number (VIN) during checkout, you receive a unit that is perfectly matched to your vehicle’s factory specifications, including its security and immobilizer systems. This means no additional programming, key relearning, or expensive dealer software is required. It’s a true plug-and-play solution designed for both professional technicians and savvy DIYers.
Installation is as simple as:
- Disconnect the Battery: This is a critical first step for any electrical work to prevent damage to the new module.
- Locate the Old ECM: On the 2006 Dodge Magnum, the ECM is found in the left-hand (driver’s side) front of the engine compartment. For the 2006 Chrysler 300, it’s in the right-hand (passenger’s side) rear of the engine compartment.
- Swap the Modules: Carefully disconnect the wiring harnesses from the old unit and remove it. Mount the new ECM in its place and securely reconnect the harnesses.
- Reconnect the Battery: Once the new module is installed, reconnect the battery terminals.
- Start Your Vehicle: Your vehicle will now start and run with its new, properly functioning brain.

Frequently Asked Questions
Is this engine computer truly ‘plug and play’?
Yes. We use the VIN you provide to flash the module with your vehicle’s specific software and security information. This ensures that once installed, it will function immediately without any further programming or dealer intervention.
Where is the ECM located on my 2006 Magnum?
On the 2006 Dodge Magnum, the Electronic Control Module is located in the engine compartment on the driver’s side, near the front. For the compatible 2006 Chrysler 300, it is on the passenger’s side in the rear of the engine compartment.
What happens if I forget to provide my VIN?
We cannot ship the module without your 17-digit VIN. The programming process is essential for the part to function in your vehicle. We will contact you to retrieve the VIN, which may delay your order. Please provide it in the checkout notes or message us to ensure swift processing.
Will this fix my transmission problems?
While the ECM communicates with the Transmission Control Module (TCM), this part is designed to resolve engine management issues. If you are having purely transmission-related problems, such as being stuck in gear, you may need a different module. However, if you have both engine and transmission symptoms, a faulty ECM is a likely cause.
Are any special tools required for installation?
No special tools are needed. Basic hand tools, such as a socket set and a screwdriver, are typically all that is required to access and replace the module.
