Is Your 2004 Durango Plagued by Mysterious Electrical Problems?
If you’re experiencing frustrating issues like stalling, erratic engine behavior, or a persistent check engine light that mechanics can’t seem to solve, the root cause is often a failing Engine Control Module (ECM). The ECM is the brain of your 4.7L V8, controlling everything from fuel injection and ignition timing to transmission shifting. When it starts to fail, it can create a cascade of problems that are difficult to diagnose. Don’t let a faulty computer keep your reliable SUV off the road. This direct-fit replacement engine computer is the definitive solution to restore your Durango’s performance and dependability.
We had a 2004 Durango 4×2 come into the shop that was a real head-scratcher. The owner complained of intermittent stalling at stoplights and occasional hard shifts, but there were no consistent trouble codes—just a generic P0601 ‘Internal Control Module Memory Check Sum Error’ that would pop up now and then. We checked the wiring, sensors, and grounds, and everything looked perfect. On a hunch, we connected a scope to the injector control circuits. We noticed that the signal to cylinder 3 would occasionally drop out for a split second, just long enough to cause a stumble but not long enough to set a misfire code. The problem was internal to the ECM. After installing a correctly programmed replacement like this one, the Durango ran like it just rolled off the factory floor. The intermittent gremlins were gone for good.
Symptoms of a Failing 2004 Durango Engine Computer
- ✔ Check Engine Light is on with codes related to module communication or sensor circuits (e.g., P0601, P0605, P0606).
- ✔ Unexplained stalling or engine shutting off while driving.
- ✔ Difficulty starting the engine, or a no-start condition where the engine cranks but won’t fire.
- ✔ Noticeable decrease in fuel economy.
- ✔ Rough idling, misfires, or hesitation during acceleration.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Seeming failure of multiple unrelated sensors at the same time.
- ✔ Inconsistent or non-functional gauges on the instrument cluster.
The Plug-and-Play Solution for Your SUV

Frequently Asked Questions
Is this engine computer really plug-and-play?
Yes, absolutely. We pre-program the unit using the VIN and mileage you provide during checkout. This ensures it integrates seamlessly with your vehicle’s existing systems, including the anti-theft (SKIM) system. No additional programming or dealer visit is required.
What information do you need from me?
To ensure perfect programming, we require your vehicle’s 17-digit 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.
Where is the ECM located on a 2004 Durango?
On the 2004 Dodge Durango, the engine computer is typically located in the engine bay, mounted to the passenger-side firewall. It will have several large electrical connectors attached to it. Always disconnect the vehicle’s battery before attempting to remove or install the module.
Will this fix my check engine light?
If the check engine light is caused by a faulty internal component of the original ECM, then yes, this replacement part will resolve the issue and the light. However, if the light is on due to a separate issue like a bad sensor or wiring problem, that issue will still need to be addressed separately.
Do I need to send my old computer (core) back?
This listing does not require a core return. You can keep or responsibly dispose of your old module without any core charge or obligation to return it.
