Restore Your HEMI’s Performance and Reliability
There’s nothing more frustrating than when your powerful Chrysler 300, Dodge Charger, or Magnum starts acting up. Whether it’s a sudden stall at a stoplight, a persistent check engine light, or a complete failure to start, a faulty Engine Control Module (ECM) can bring your vehicle to a standstill. You’re not just losing a mode of transportation; you’re losing the performance and driving experience you expect from a HEMI-powered machine. This pre-programmed ECM is the definitive, hassle-free solution to get you back on the road with confidence.
Common Symptoms of a Failing ECM & Your Solution
A failing engine computer can manifest in numerous ways, often mimicking other sensor or component failures. If you’re experiencing any of the following, a bad ECM is a likely culprit:
- Check Engine Light: Especially with internal module error codes like P0601, P0606, or other P06xx codes.
- No-Start Condition: The engine cranks but refuses to start, despite having fuel and spark.
- Stalling or Rough Idle: The engine may stall intermittently, run poorly, or idle erratically for no apparent reason.
- Poor Performance & Fuel Economy: A noticeable drop in power, hesitation during acceleration, and a sudden decrease in MPG.
- Communication Errors: Your scan tool may be unable to communicate with the ECM, or you may see U-series communication fault codes.

An Expert’s Note on Mopar ECMs
“Over my 20 years on the shop floor, I’ve seen countless Chrysler, Dodge, and Jeep vehicles with perplexing electrical issues. A common point of failure on this LX platform (300, Charger, Magnum) is the main engine computer. Before you spend hundreds chasing sensors, it’s crucial to verify the brain of the operation. A key diagnostic tip is to check for a stable 5-volt reference at key sensors like the TPS and MAP sensor. If that voltage is erratic or missing, it often points directly back to an internal ECM fault. Installing a pre-programmed 2007 Chrysler 300 ECM 05094803AC isn’t just swapping a part; it’s restoring the vehicle’s central nervous system and giving the owner their car back, often running better than it has in years.”
Frequently Asked Questions
Is this ECM really “Plug and Play”?
Yes, absolutely. We program the unit with the specific VIN and mileage you provide during checkout. This means once you receive it, you simply disconnect the battery, swap the old module with the new one, reconnect the battery, and start the car. No further programming or dealer intervention is necessary.
What information do you need from me to program it?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) and the current mileage. You can typically find the VIN on your dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my car’s specific problem?
This ECM is the correct solution for issues directly caused by a faulty engine computer, such as internal processor errors (P0601, P0606), no-start conditions where the ECM is unresponsive, and multiple unrelated sensor codes appearing at once. While it solves the vast majority of electronic engine issues, we always recommend a proper diagnosis by a qualified mechanic to confirm the ECM is the root cause.
How do I confirm my original ECM is the problem?
A professional diagnosis is best. However, common indicators include a lack of communication with a scan tool, specific internal fault codes, and ruling out other possibilities like faulty wiring, grounds, or power supply to the module. Checking for a consistent 5-volt reference signal to your main engine sensors is also a key diagnostic step.
Does this fit vehicles other than the 2007 Chrysler 300?
Yes. This 2007 Chrysler 300 ECM 05094803AC is also the correct computer for the 2007 Dodge Charger and 2007 Dodge Magnum equipped with either the 5.7L or 6.1L HEMI V8 engines.
What is the warranty on this part?
This unit is backed by our one-year replacement warranty, giving you confidence and security in your purchase.
