Restore Peak Performance to Your 2012 Dodge Avenger or Chrysler 200
Is your 2012 Dodge Avenger or Chrysler 200 suffering from erratic behavior, poor fuel economy, or a dreaded no-start condition? The Engine Control Module (ECM), often called the engine computer, is the brain of your vehicle’s operation. When it begins to fail, it can cause a cascade of confusing and frustrating problems. This direct-fit replacement Engine Control Module, part number 68068451AB, is the definitive solution to get your vehicle running reliably again.
From the Diagnostic Bay
We had a 2012 Avenger come into the shop that was a real head-scratcher. The customer complained of random stalling at stoplights and transmission shifts that felt harsh and unpredictable. The check engine light was on, but the codes were all over the place—from O2 sensor faults to transmission communication errors. We checked the wiring harnesses and sensors, but everything looked solid. After hours of diagnostics, we decided to inspect the ECM. We found subtle corrosion on one of the main connector pins. We swapped in a pre-programmed module, and it was like a different car. The engine ran smoothly, the transmission shifted perfectly, and all the ghost codes vanished. It’s a classic case of a failing central computer causing system-wide chaos.
Is Your Vehicle Showing These Symptoms?
A failing engine computer can manifest in numerous ways. If you’re experiencing any of the following issues, a faulty ECM could be the culprit:
- ✔ Check Engine Light is illuminated with various, often unrelated, trouble codes.
- ✔ The engine cranks but refuses to start.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Rough idling, stalling, or misfires.
- ✔ Harsh or delayed automatic transmission shifting.
- ✔ Communication issues with diagnostic scan tools.
- ✔ Intermittent electrical problems that seem to have no other cause.

Frequently Asked Questions
What is an ECM and what does it do?
The Engine Control Module (ECM) is your car’s main computer. It controls critical functions like fuel injection timing, spark timing, transmission shifting, and emissions systems to ensure the engine runs efficiently and smoothly.
Is this module truly plug-and-play?
Yes. We program the module with your vehicle’s VIN and mileage before shipping. This means it will work with your existing keys and security system right out of the box, with no additional programming needed.
Where is the ECM located on my 2012 Avenger or 200?
On the 2012 Dodge Avenger and Chrysler 200, the ECM is typically located in the engine bay, mounted to the firewall or near the battery. It is a silver metal box with several large electrical connectors.
How can I be sure my ECM is the problem?
While the symptoms listed are strong indicators, it’s always best to have a qualified mechanic perform a full diagnostic. Common steps include checking for consistent communication with a scan tool, verifying power and ground signals to the ECM, and ruling out sensor or wiring issues.
What information do you need from me to program the module?
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 your vehicle’s registration or insurance card.
