Is Your Dodge Avenger, Sebring, or Journey Running Rough?
If you’re dealing with frustrating and unpredictable engine problems in your 2008-2010 Dodge or Chrysler vehicle, a failing Engine Control Module (ECM) is a very likely culprit. 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 starts to fail, it can cause a cascade of issues that are often difficult to diagnose, leading to wasted time and money on unnecessary repairs.
This replacement Engine Control Module, part number 68046281AB, is the definitive solution to get your vehicle running smoothly again. Forget about expensive dealership visits and the hassle of programming. We handle all the complex software work for you. Simply provide your vehicle’s VIN and current mileage during checkout, and we will flash the module with your vehicle’s specific data. It arrives at your door ready for a straightforward, plug-and-play installation.
From the Diagnostic Bay
We had a 2009 Dodge Journey with the 2.4L engine come into the shop with an intermittent no-start condition and a check engine light for a camshaft position sensor. The owner had already replaced the sensor twice with no luck. After connecting our scan tool, we noticed the 5-volt reference signal to the sensor was dropping out randomly. Instead of chasing wires, we went straight to the ECM. A failing driver inside the module was causing the voltage drop. We installed one of our pre-programmed units, and the Journey fired right up and ran perfectly. It’s a classic case where the symptom points to a sensor, but the root cause is the computer that controls it.
Common Symptoms of a Failing Engine Computer
- ✔ Persistent Check Engine Light (CEL) that won’t clear or returns immediately after clearing.
- ✔ Engine stalling, stumbling, or hesitating, especially under load.
- ✔ Complete no-start condition where the engine cranks but will not fire.
- ✔ Poor fuel economy and a noticeable loss of engine power.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Communication errors with diagnostic scan tools (e.g., “No Communication with ECM”).
- ✔ Multiple unrelated trouble codes being stored simultaneously.

Frequently Asked Questions
Is this ECM truly Plug and Play?
Yes. We program the module with the VIN and mileage you provide. This means it will be fully compatible with your vehicle’s systems, including the immobilizer, without any need for additional programming from a dealer or mechanic.
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 driver’s side dashboard (visible through the windshield) or on your vehicle’s registration or insurance card.
Will this fix my car’s specific problem?
This module will correct issues directly caused by a faulty ECM. While the symptoms listed are common indicators of ECM failure, we always recommend a proper diagnosis by a qualified mechanic to confirm the ECM is the source of the problem before ordering.
How do I find my original part number?
Your original part number is printed on a sticker on the ECM itself. The module is typically located in the engine bay. The number will usually start with a ‘P’ followed by a series of numbers, or it will match one of the many compatible numbers listed on this page.
Does this part fit vehicles other than the Dodge Avenger?
Yes, this ECM is also a direct fit for the 2008-2010 Chrysler Sebring and 2009-2010 Dodge Journey, provided they are equipped with the 2.4L 4-cylinder engine. Please check the detailed fitment list on this page to confirm compatibility.
