Is Your 2007 Chrysler Aspen, Dodge Durango, or Ram 1500 Running Rough?
A failing Engine Control Module (ECM), also known as the engine computer, can be the source of countless frustrating and hard-to-diagnose issues in your 5.7L HEMI-powered vehicle. From a persistent Check Engine Light to a vehicle that won’t start at all, the ECM is the brain of your engine’s operation. When it falters, performance, reliability, and fuel economy suffer. This direct-fit replacement engine computer, part number 5094355AB, is the definitive solution to restore your vehicle’s factory performance and get you back on the road with confidence.
Common Symptoms of a Failing 5.7L HEMI ECM
If you’re experiencing any of the following issues, a faulty engine computer could be the culprit. While it’s always wise to perform a full diagnostic check, these symptoms are strongly indicative of an ECM problem in 2007 Aspen, Durango, and Ram 1500 models:
- ✔ Check Engine Light: The light is on, and you may have codes related to sensor circuits (P0100-P0600 series), communication errors (U-codes), or random misfire codes.
- ✔ Engine Stalling or Hesitation: The engine may stall unexpectedly while driving or at idle, and hesitate or stumble during acceleration.
- ✔ No-Start Condition: The engine cranks but refuses to start. You may notice a lack of spark or fuel injector pulse, which are controlled by the ECM.
- ✔ Poor Fuel Economy: A malfunctioning computer can’t properly manage the air-fuel mixture, leading to a noticeable drop in MPG.
- ✔ Rough Idle: The engine idles erratically, surging or dropping RPMs without reason.
- ✔ Transmission Shifting Problems: The ECM works in tandem with the transmission controller. A faulty ECM can cause harsh shifting, failure to shift, or incorrect gear selection.
- ✔ Loss of Power: The vehicle feels sluggish and lacks the power you expect from the 5.7L HEMI engine.
From the Diagnostic Bay
We had a 2007 Dodge Durango 5.7L come into the shop with a classic ghost-in-the-machine problem. The owner complained of intermittent stalling at red lights and a check engine light that came and went. Our initial scan showed a handful of seemingly unrelated codes—an O2 sensor circuit fault, a throttle position sensor error, and a generic communication code. We checked the wiring, grounds, and the sensors themselves, and everything tested fine. The intermittent nature of the problem pointed us toward the central processing unit. After confirming stable power and ground to the ECM, we knew the internal logic was failing. We installed a pre-programmed 2007 Aspen Engine Computer (which is the same unit for the Durango), and the vehicle ran perfectly. The codes vanished, and the stalling issue was completely resolved. It’s a textbook case of how a failing ECM can send you chasing phantom issues all over the engine bay.

Frequently Asked Questions
Is this engine computer truly “Plug & Play”?
Yes. 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 vehicle, like the ignition and security system. You will not need to take it to a dealer for additional programming.
Where is the ECM located on my 2007 Aspen or Durango?
The Engine Control Module on the 2007 Chrysler Aspen and Dodge Durango is typically located in the engine bay, mounted to the passenger side (RH) fender wall. Always disconnect the negative battery terminal before attempting to remove or install the module.
What information do you need from me to program the module?
During the checkout process, we will require your vehicle’s 17-digit VIN (Vehicle Identification Number) and the current mileage. This information is critical for programming the module correctly for your specific vehicle.
Will this fix my check engine light?
If the check engine light is on due to an internal failure of the original ECM, then this replacement part will solve the problem. However, if the light is on because of a separate faulty sensor or wiring issue, that component will still need to be addressed. This module will fix any codes directly caused by a failing computer.
Do I need to perform any relearn procedures after installation?
In most cases, no special procedures are needed. However, some vehicles may benefit from a simple idle relearn, which typically involves letting the engine idle for a few minutes to allow the new computer to adjust. Your vehicle’s service manual can provide specific details if necessary.
