Restore Peak Performance to Your Chrysler 300 or Dodge Magnum
Is your 2005 Chrysler 300 or Dodge Magnum suffering from perplexing issues like stalling, a persistent check engine light, rough idling, or a complete no-start condition? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your vehicle’s engine. A faulty ECM can cripple your car’s performance, fuel economy, and reliability. This direct-fit replacement ECM is the definitive solution to get your vehicle running like new again, without the exorbitant costs and hassle of a dealership visit.
We had a 2005 Dodge Magnum AWD come into the shop that had its owner completely stumped. The car would run fine for a few minutes, then suddenly stall and refuse to restart for an hour. The check engine light was on, but the codes were intermittent and pointed to multiple unrelated sensors. After hours of chasing electrical gremlins, we hooked up our advanced diagnostic scanner and noticed the ECM would intermittently lose communication. We swapped in a pre-programmed module just like this one, and the Magnum fired right up and ran perfectly. It’s a reminder that when you have multiple, confusing electronic issues, the problem often lies with the brain of the operation: the ECM.
Common Symptoms of a Failing Engine Computer
- ✔ Persistent Check Engine Light (CEL) that won’t clear or returns immediately.
- ✔ Engine stalling or shutting off unexpectedly while driving.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Rough or erratic idling and poor engine performance.
- ✔ Transmission shifting problems or harsh shifts.
- ✔ Communication errors when using a diagnostic scan tool.

Frequently Asked Questions
What is an ECM and what does it do?
The Engine Control Module (ECM), also known as the engine computer, is the main computer that controls all aspects of your vehicle’s engine. It takes data from sensors all over the engine to manage fuel injection, ignition timing, emissions systems, and more to ensure optimal performance and efficiency.
Is this part really “plug and play”?
Yes. We pre-program the module to your vehicle’s specific VIN and mileage before shipping. This means you can install it yourself without needing any special tools or a trip to the dealership for further programming. It’s a direct, ready-to-install solution.
How do I know for sure that my ECM is the problem?
While the symptoms listed are strong indicators, it’s always best to have a qualified mechanic perform a full diagnostic. They can rule out other potential issues like faulty wiring, sensors, or fuel system problems to confirm the ECM is the root cause before you order a replacement.
Where is the ECM located on my 2005 300 or Magnum?
On the 2005 Chrysler 300 and Dodge Magnum, the ECM is typically located in the engine compartment on the driver’s side (LH side), near the front of the vehicle, often close to the fuse box or firewall.
What information do you need from me to program the module?
During the checkout process, we will require your vehicle’s 17-digit Vehicle Identification Number (VIN) and the current mileage. This information is essential for us to program the module correctly for your specific car.
