- Persistent Check Engine Light (CEL) that won’t clear
- Engine stalling or shutting off while driving
- Complete no-start condition
- Poor engine performance and reduced fuel economy
- Communication errors with diagnostic scan tools
- Specific Diagnostic Trouble Codes (DTCs) like P0601, P0605, or P0606

An Expert’s Note on Chrysler Programming
Unlike many other vehicles, Chrysler products from this era use a sophisticated Sentry Key Immobilizer Module (SKIM) that is tied directly to the ECM via the VIN. Simply installing a used, non-programmed computer from another car will result in a hard no-start condition and a flashing security light on your dash. Our pre-programming service correctly pairs this ECM to your car’s unique identity before it even ships. This is why a properly programmed 2005 Chrysler 300 ECM is critical—it saves you time, money, and the headache of towing your car for specialized service.
Stop guessing and replace the core of your engine’s management system. This 2005 Chrysler 300 ECM is the definitive solution for restoring the powerful, smooth driving experience you love. Order today and get your car back to its peak condition with confidence.
Frequently Asked Questions
Is this ECM truly Plug & Play?
Yes, absolutely. We use the Vehicle Identification Number (VIN) and mileage you provide during checkout to program the computer. When it arrives, you simply install it, and the vehicle will start and run without any additional programming required.
How do I know for sure that my ECM is the problem?
While the symptoms listed above are strong indicators, a definitive diagnosis from a qualified mechanic is always the best course of action. Common diagnostic codes pointing to a bad ECM include P0601 (Internal Control Module Memory Check Sum Error) and P0606 (ECM/PCM Processor Fault). A professional diagnosis can rule out other potential issues like faulty wiring or sensors.
Will this fit my 2005 Dodge Magnum?
Yes, this ECM is compatible with the 2005 Dodge Magnum equipped with a 6-cylinder engine and Rear-Wheel Drive (RWD), specifically for models manufactured from 06/28/04 onwards. It is also compatible with the 2005 Chrysler 300 with the same options.
What information do you need from me to program it?
We require your vehicle’s 17-digit VIN and the current mileage. The VIN is essential for programming the unit to communicate with your car’s security and other electronic systems. It can be found on your dashboard (visible through the windshield), on your vehicle’s registration, or on the driver’s side door jamb sticker.
Does this work for the V8 Hemi models?
No, this particular part is specifically for the 6-cylinder, RWD models of the Chrysler 300 and Dodge Magnum. The V8 models use a different engine computer with unique software. Please ensure your vehicle matches the fitment details before ordering.
