Common Symptoms & Your Solution
A failing engine computer can manifest in numerous ways. If you’re experiencing any of the following, a replacement ECM is the most likely solution:
- No-Start or Hard-Start Conditions: The engine cranks but refuses to start, or takes an excessive amount of time to fire up.
- Engine Stalling or Misfiring: The engine randomly shuts off while driving or idles erratically, often accompanied by cylinder misfire codes (e.g., P0300-P0308).
- Reduced Power and Fuel Economy: Your vehicle feels sluggish, unresponsive, and is consuming more fuel than usual.
- Persistent Check Engine Light (CEL): You may see various Diagnostic Trouble Codes (DTCs), especially those related to sensor circuits (P0100-P0600 series) or module communication errors (U-codes).
- Transmission Shifting Problems: The ECM plays a key role in communicating with the transmission controller, and a fault can lead to harsh or incorrect shifting.
This module is the direct fix for these issues, restoring communication between all your vehicle’s critical systems and ensuring your engine operates exactly as the factory intended.

Expert Insight: More Than Just a Box
In a modern vehicle like your 2007 HEMI-powered Mopar, the ECM isn’t just a simple computer—it’s the central nervous system. It communicates constantly over a complex network (CAN bus) with dozens of other modules, from the transmission controller to the ABS and even the instrument cluster. That’s why a ‘one-size-fits-all’ junkyard part won’t work. Our programming process ensures that your new plug and play 2007 Chrysler 300 ECM has the correct software and security information, allowing it to integrate seamlessly into your vehicle’s unique electronic ecosystem right out of the box. This is the key to a successful, lasting repair.
Frequently Asked Questions
What does “Plug and Play” actually mean?
It means the engine computer will arrive at your door fully programmed with your car’s specific Vehicle Identification Number (VIN) and security information. You simply need to disconnect the battery, swap the old module with the new one, and reconnect the battery. No further programming or dealer visits are necessary.
Do I need to send my old ECM to you?
No, there is no core charge or need to send us your old part. This is a direct purchase, which simplifies the process and gets your vehicle repaired faster.
Will this fix my specific check engine light codes?
This ECM is a common solution for a wide range of codes related to engine management, sensor circuits, and module communication. While it corrects issues originating from the computer itself, it’s essential to ensure the problem isn’t a faulty sensor or wiring harness. However, if you’ve been chasing multiple, seemingly unrelated codes, a failing ECM is a very likely culprit.
Is this compatible with my factory security system?
Yes. During the programming process, we flash the module with your car’s specific security key information from the VIN you provide. This allows it to work perfectly with your existing keys and anti-theft system.
What if my part number isn’t an exact match to 05094803AI?
This module is a direct replacement for a range of part numbers, including 05094803AA through 05094803AJ and 05094811AE. As long as your vehicle is a 2007 300, Charger, or Magnum with a 5.7L or 6.1L engine, this is the correct computer for you, even if the last letters on your original part differ.
