Is Your Chrysler 300 or Dodge Magnum Running Rough?
If you’re experiencing perplexing issues like a persistent check engine light, sudden stalling, erratic shifting, or a complete no-start condition in your 2006 Chrysler 300 or Dodge Magnum 3.5L AWD, the culprit is often the very brain of your vehicle: the Engine Control Module (ECM). This critical component manages everything from fuel injection and ignition timing to transmission signals and emissions controls. When it begins to fail, it can create a cascade of problems that are frustrating and difficult to diagnose.
Don’t let a faulty computer keep your car off the road. This is a direct-fit replacement Engine Control Module, part number 05094133AD, specifically for the 2006 3.5L AWD models. The best part? We eliminate the most significant hurdle of replacement: programming. We professionally flash this module with your vehicle’s specific 17-digit VIN and mileage before it ships. This means it arrives at your door ready for a true plug-and-play installation, saving you hundreds of dollars in dealership programming fees and towing costs.
From the Diagnostic Bay
We had a 2006 Dodge Magnum 3.5L AWD towed in that was a real head-scratcher. The owner had replaced the throttle body, MAP sensor, and even the alternator trying to chase down intermittent stalling and a flickering check engine light with a host of unrelated codes. On our diagnostic scanner, the 5-volt reference signal to several sensors was fluctuating wildly. Instead of continuing to replace parts, we traced the circuit back to its source: the ECM. The internal voltage regulator was failing, sending erratic signals throughout the system. A new, properly programmed 2006 300 engine computer was installed, and the Magnum ran perfectly. It’s a classic case of symptoms appearing far from the source of the problem.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) that won’t clear or returns immediately.
- ✔ Vehicle refuses to start or cranks endlessly without firing.
- ✔ Sudden stalling or hesitation during acceleration.
- ✔ Noticeable decrease in fuel economy.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Misfire codes even after replacing plugs, coils, and injectors.
- ✔ Cooling fans running constantly or not at all.
The Simple Solution: A Pre-Programmed 2006 300 Engine Computer
The complexity of modern vehicles means you can’t just swap an ECM from another car. It must be coded to your vehicle’s unique VIN to communicate with the other modules, like the security system and transmission controller. Our service handles this for you. By providing your VIN during checkout, you receive a unit that is perfectly matched to your car’s factory settings. The installation is straightforward for a DIY mechanic with basic tools. Simply disconnect the battery, locate your old module (in the RH rear of the engine compartment on the 300, or LH front on the Magnum), swap the electrical connectors, and mount the new unit. Reconnect the battery, and you’re ready to go.
This module is a direct replacement for multiple part numbers, including: 04606838ac, 05094133ab, 05094133ad, 05094592af, 4606838ac, and 5094593ab. Please verify your part number and vehicle options to ensure proper fitment.

No. This engine computer comes fully programmed to your vehicle’s specific VIN. It is a plug-and-play solution that requires no additional programming or flashing once you receive it.
Where do I provide my VIN number?
Please enter your complete 17-digit VIN in the notes section during the checkout process or send it to us in a message immediately after placing your order. We cannot program and ship the module without your VIN.
Is this part difficult to install?
For most individuals with basic mechanical skills, the installation is straightforward. It typically involves disconnecting the vehicle’s battery, unplugging the electrical harnesses from the old module, unbolting it, and then reversing the process to install the new one. No special tools are usually required.
What happens if I forget to provide my VIN?
Your order will be placed on hold. We will contact you via email or message to request the VIN. To ensure the fastest possible processing and shipping, please provide it at the time of purchase.
Will this fix my car’s specific problem?
If your vehicle’s issues have been correctly diagnosed as a faulty ECM, this part will resolve them. It’s crucial to ensure a proper diagnosis has been performed, as other failing components can sometimes mimic ECM failure symptoms.
