Is Your Dodge Avenger Running Rough?
If you’re dealing with a frustrating check engine light that won’t go away, poor fuel economy, stalling, or a no-start condition in your 2008, 2009, or 2010 Dodge Avenger, Sebring, or Journey, the problem may lie with a faulty Engine Control Module (ECM). The ECM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to emissions systems and transmission shifting. When it fails, it can cause a wide range of perplexing and often intermittent issues that can be difficult to diagnose.
Don’t let a failing computer keep your car off the road. This replacement Engine Control Module is the perfect solution to restore your vehicle’s performance and reliability. It arrives at your door fully programmed to your specific Vehicle Identification Number (VIN) and mileage. This means there’s no need for an expensive trip to the dealership for programming—it’s a true plug-and-play fix that you can often install yourself in under an hour.
From the Diagnostic Bay
We had a 2009 Dodge Journey with the 2.4L engine come into the shop with a classic ghost-in-the-machine problem. The owner complained of random stalling at stoplights and an occasional hard start. We checked everything—fuel pressure was good, sensors tested fine, and there were no consistent trouble codes. After hours of chasing wires, we decided to monitor the ECM’s data stream. We noticed the 5-volt reference signal to the sensors would momentarily drop out, causing the engine to stumble. Swapping in a known-good, programmed ECM like this one solved the problem instantly. The internal voltage regulator on the original board was failing, a common issue that a simple part swap can fix.
Symptoms of a Failing 2.4L Engine Computer
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Rough or erratic idling.
- ✔ Transmission shifting problems or getting stuck in ‘limp mode’.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Misfire codes even after replacing spark plugs and coils.

Frequently Asked Questions
Is this engine computer really plug-and-play?
Yes, absolutely. We program the unit with your vehicle’s specific VIN and mileage before shipping. This ensures it communicates correctly with all other modules in your car, including the security system. No further programming or dealer visit is required.
How do I know for sure that my ECM is the problem?
While the symptoms listed above are strong indicators, it’s always best to have a proper diagnosis performed. Key signs include multiple unrelated error codes, a no-start condition where the engine cranks but won’t fire, or a complete loss of communication with the ECM when using a scan tool. If other components like sensors, wiring, and fuel delivery have been ruled out, the ECM is the likely culprit.
Where is the ECM located on my 2009 Dodge Avenger?
On most 2008-2010 Dodge Avengers, Sebrings, and Journeys with the 2.4L engine, the ECM is located in the engine bay, typically mounted to the firewall or inner fender well. It’s a silver metal box with several large electrical connectors. Always disconnect the battery before attempting to remove or install the ECM.
Will this fix my vehicle’s emissions test failure?
If the failure is caused by an ECM-related trouble code (like an internal processor error or sensor circuit fault), then yes, replacing the module should resolve the issue and allow your vehicle to pass the emissions test after completing a drive cycle.
What information do you need from me to program the computer?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) and the current mileage. You can typically find the VIN on your driver’s side dashboard (visible through the windshield) or on the driver’s side door jamb sticker. Please double-check it for accuracy when ordering.
