Is Your 2008 Avenger or Sebring Running Rough?
A failing Engine Control Module (ECM), also known as an engine computer, can be the source of countless frustrating and hard-to-diagnose issues. If your vehicle is experiencing erratic behavior, poor performance, or simply won’t start, the ECM is a likely culprit. It’s the brain of your vehicle, controlling everything from fuel injection and ignition timing to transmission shifting and emissions. When it fails, the symptoms can be widespread and confusing, often leading to incorrect diagnoses and unnecessary replacement of other parts.
From the Diagnostic Bay
We had a 2008 Dodge Avenger come into the shop that was a real head-scratcher. The owner had already replaced the spark plugs, ignition coils, and even a camshaft position sensor at another garage, but it still had a persistent, intermittent misfire and would occasionally stall at stoplights. The check engine light was on with a handful of seemingly unrelated codes. After hours of checking wiring and sensor data, we noticed the voltage reference signal from the ECM was fluctuating wildly under load. This tiny inconsistency was enough to throw the whole system into chaos. We installed one of our pre-programmed ECMs, and the car immediately ran like new. It’s a classic case where the root cause was the central computer, not the components it controls.
Common Symptoms of a Failing ECM
- âś” Persistent Check Engine Light (CEL) that won’t clear.
- âś” Engine stalling, stumbling, or misfiring for no apparent reason.
- âś” A complete no-start condition where the engine cranks but won’t fire up.
- âś” Noticeable decrease in fuel economy.
- âś” Harsh or erratic automatic transmission shifting.
- âś” Communication errors with diagnostic scan tools.
- âś” Issues with other electronic systems, like cooling fans running constantly.

Frequently Asked Questions
Is this engine computer truly “Plug & Play”?
Yes. We program the module with the latest software updates from the manufacturer and flash it specifically to your vehicle’s VIN and mileage. When you receive it, no further programming is required. Simply install it, and you’re ready to go.
What information do you need from me after I order?
After you place your order, we will need your vehicle’s 17-digit VIN and the current mileage. This ensures we can program the module perfectly for your specific car.
Will this fix my car’s problem?
This module will correct any issue directly caused by a faulty ECM. However, it’s crucial that your vehicle has been properly diagnosed. If the issue is with a sensor, wiring, or another component, replacing the ECM will not solve the problem. We recommend a thorough diagnosis by a qualified mechanic to confirm the ECM is the point of failure.
How do I find my original part number to confirm a match?
Your original part number is printed on a white label directly on the metal case of your existing engine computer. It will typically start with a ‘P’ followed by a series of numbers, such as ‘P05150245AC‘. Matching this number to our compatible list is the best way to ensure a perfect fit.
Do I need to perform a security or key relearn procedure?
Because we program the unit with your VIN, the security information is transferred, and in most cases, no additional security relearn is necessary. The module will recognize your existing keys, making for a seamless installation.
