Is Your Dodge Avenger, Sebring, or Journey Running Poorly?
If you’re dealing with a persistent check engine light, erratic engine behavior, or a vehicle that simply won’t start, a failing Engine Control Module (ECM) is a very likely culprit. The ECM is the brain of your vehicle’s engine, controlling everything from fuel injection and spark timing to transmission shifts and emissions. When it fails, it can cause a cascade of frustrating and difficult-to-diagnose problems. This replacement engine computer, part number 05187274AD, is the definitive solution for restoring your vehicle’s performance and reliability.
From the Diagnostic Bay
We had a 2009 Dodge Journey come into the shop that was driving the owner crazy. It would stall intermittently at stoplights, and two other shops had already replaced the crankshaft and camshaft position sensors to no avail. The check engine light was on, but the codes were generic communication errors that didn’t point to a specific sensor. After confirming power and ground to the ECM were good, we connected a scope and saw the 5-volt reference signal dropping out randomly. That’s a classic internal failure of the ECM. We installed a pre-programmed unit just like this one, and the Journey ran perfectly. It’s a reminder that sometimes the problem isn’t the sensors, but the computer that reads them.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) that won’t clear or returns immediately.
- ✔ Vehicle refuses to start or has difficulty starting.
- ✔ Rough or unstable idling and frequent stalling.
- ✔ Noticeable decrease in fuel economy.
- ✔ Poor engine performance, including hesitation and lack of power.
- ✔ Automatic transmission shifting issues.
- ✔ Inability for diagnostic scan tools to communicate with the module.
The Plug-and-Play Solution for Your 2008-2010 Avenger ECM
The biggest hurdle in replacing an engine computer has always been the expensive and time-consuming programming required at a dealership. We eliminate that step completely. When you order from us, we flash the module with the latest software updates from Chrysler and program it specifically to your vehicle’s unique Vehicle Identification Number (VIN) and current mileage. This means the unit arrives at your door ready for immediate installation. There are no extra trips to the dealer, no hidden programming fees, and no complicated tools needed. It’s a true plug-and-play fix.
Installation is Straightforward
While professional installation is always an option, many DIY mechanics can handle this replacement. The process generally involves disconnecting the vehicle’s battery, locating the existing ECM (often found in the engine bay near the firewall or fender), carefully unplugging the electrical connectors, unbolting the old module, and then installing the new one in its place. Once the new module is secured and the connectors are plugged in, simply reconnect the battery, and you’re ready to go. Your vehicle’s keys will be recognized, and all systems will function as they should.

Frequently Asked Questions
Is this engine computer really “Plug and Play”?
Yes, absolutely. We program the module to your vehicle’s specific VIN before it ships. This process ensures that when you install it, the computer will communicate seamlessly with your vehicle’s other modules and security system without any additional programming required.
Where is the ECM located on my 2009 Dodge Avenger?
On most 2008-2010 Dodge Avengers, Chrysler Sebrings, and Dodge Journeys with the 2.4L engine, the ECM is located in the engine compartment. It’s typically mounted to the driver’s side inner fender, near the battery and behind the headlight assembly. It’s a silver metal box with several large electrical connectors.
How can I be sure the ECM is the problem and not a sensor?
While symptoms can overlap, a key indicator of ECM failure is having multiple, unrelated error codes, communication errors with a scan tool, or having already replaced sensors without fixing the issue. If the vehicle exhibits issues like intermittent stalling or no-start conditions that aren’t tied to a specific mechanical part, the ECM is a primary suspect. A professional diagnosis is the best way to be certain.
Do I need to send my old computer back?
This listing does not require a core return. You can keep your old part or dispose of it responsibly without any additional charges or hassle.
What information do you need from me to program the module?
All we need is your vehicle’s 17-digit Vehicle Identification Number (VIN). You can typically find this on your vehicle’s registration, insurance card, or on a plate on the driver’s side dashboard visible through the windshield. Please provide the VIN during the checkout process to ensure correct programming.
