Restore Peak Performance to Your HEMI-Powered Mopar
If you’re dealing with frustrating issues like stalling, a persistent check engine light, or erratic engine behavior in your 2007 Dodge Magnum, Charger, or Chrysler 300, the root cause is often a failing Engine Control Module (ECM). As the central computer of your vehicle, a faulty ECM can cripple performance and leave you stranded. I’ve seen it hundreds of times in the shop: a powerful 5.7L or 6.1L HEMI that suddenly runs rough or won’t start at all. The diagnosis often points directly to an internal ECM failure, a problem that can seem daunting and expensive to fix—until now.
This replacement Engine Computer, part number 05094811AE, is the definitive solution. We eliminate the biggest headache of ECM replacement: programming. Before this unit ships, our technicians will flash it with your vehicle’s specific Vehicle Identification Number (VIN) and current mileage. This means it arrives at your door completely ready for installation. There’s no need for a trip to the dealership, no expensive diagnostic tool rentals, and no complex programming procedures. It’s a true plug-and-play fix that gets your car back on the road quickly and reliably.
A Technician’s Notebook: The Intermittent Stall
A customer brought in his ’07 Charger 6.1L with a ghost of a problem. It would run perfectly for days, then suddenly stall at a stoplight and refuse to restart for 20 minutes. No consistent codes, just a random P0606 (PCM Processor Fault) that would clear itself. After checking fuel pressure, sensors, and wiring harnesses, everything looked fine. On a hunch, I tapped the ECM housing with a screwdriver handle while the engine was idling, and it immediately stumbled. The issue was an internal fracture on the circuit board, only causing a problem when the unit got hot. Swapping in a pre-programmed ECM like this one solved the issue permanently. It’s a classic failure mode for these modules.
Is Your Vehicle Showing These Symptoms?
A failing ECM can manifest in various ways. If you’re experiencing any of the following, it’s a strong indicator that your engine computer needs replacement:
- ✔ Engine stalling or shutting off while driving
- ✔ Complete no-start condition where the engine cranks but won’t fire
- ✔ Check Engine Light is illuminated with codes like P0601 (Internal Control Module Memory Check Sum Error) or P0606
- ✔ Poor fuel economy and noticeable loss of power
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Communication issues with diagnostic scan tools
Your Straightforward Installation Guide
Installing your 2007 Magnum Engine Computer is a simple process that most DIYers can handle in under an hour with basic hand tools. Follow these steps to get your vehicle running right again.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and secure it away from the post to prevent any accidental electrical shorts.
- Locate the ECM: On these vehicles, the engine computer is found in the front of the engine compartment on the driver’s side (LH side), typically mounted near the firewall or shock tower.
- Disconnect the Wiring: Carefully unplug the main electrical connectors from the module. Most have a locking tab that needs to be depressed or slid to release the harness.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket. There are usually three or four bolts holding it in place.
- Install the New ECM: Mount your new, pre-programmed engine computer in the same location and secure it with the original bolts.
- Reconnect Everything: Plug the wiring harnesses back into the new module until they click securely in place. Reconnect the negative battery terminal. The installation is now complete—no further programming is needed!

Frequently Asked Questions About The 2007 Magnum Engine Computer
Do I need to have this computer programmed by a dealer?
No. This is the primary benefit of our service. We program the engine computer to your vehicle’s specific VIN and mileage before it ships. It will arrive ready to install, with no additional programming required.
What information do you need from me?
After you place your order, we will need your vehicle’s 17-digit VIN (Vehicle Identification Number) and the current mileage. This ensures the module is a perfect match for your car’s security and instrument cluster systems.
Where is the ECM located on my 2007 Dodge Magnum?
The Electronic Control Module (ECM) is located in the engine bay, on the driver’s side (LH side), near the front of the vehicle. It’s a silver metal box with several large electrical connectors.
Will this fix my P0601 check engine light code?
Yes, in the vast majority of cases. The diagnostic trouble code P0601 specifically indicates an internal memory or checksum error within the engine computer itself. Replacing the faulty module with this pre-programmed unit is the correct and definitive repair for that code.
Is this compatible with other part numbers?
Absolutely. This ECM, part number 05094811AE, is a direct replacement for a long list of previous part numbers, including 05094803AA, 05094803AB, 05094803AC, 05094803AD, 05094803AE, 05094803AF, 05094803AG, 05094803AH, 05094803AI, and 05094803AJ.
