Is Your 2004 Durango Running Rough? The ECM Might Be the Culprit.
If you’re dealing with frustrating issues like a persistent check engine light, stalling, poor fuel mileage, or erratic shifting in your 2004 Dodge Durango 4.7L, the root cause is often a failing Engine Control Module (ECM). The ECM is the brain of your vehicle, managing everything from fuel injection and ignition timing to transmission performance. When it starts to fail, it can create a cascade of problems that are difficult to diagnose and can sideline your SUV. Don’t let a faulty computer keep you off the road. This direct-replacement ECM is the definitive solution to restore your Durango’s performance and reliability.
From the Diagnostic Bay
We had a 2004 Durango 4.7L come into the shop with a complaint of intermittent stalling at stoplights and a harsh 1-2 shift. The owner had already replaced the throttle position sensor and the transmission fluid, but the problem persisted. No specific transmission codes were present, only a generic communication error code. After checking the wiring harness for damage, we hooked up a scope to the ECM’s output signals. We found that the signal controlling the ignition coil for cylinder 3 was dropping out sporadically, causing a misfire that was just subtle enough not to trigger a specific misfire code but severe enough to cause the engine to stumble and stall. Swapping in a known-good, programmed ECM immediately solved both the stalling and the harsh shifting. It’s a classic case of how a failing ECM can send you chasing ghosts all over the vehicle.

Frequently Asked Questions
Is this ECM really “Plug and Play”?
Yes, absolutely. We program the unit with your vehicle’s VIN and current mileage before shipping. This ensures it communicates correctly with your Durango’s other modules, like the instrument cluster and anti-theft system, without any additional programming required.
Where is the ECM located on a 2004 Dodge Durango?
On the 2004 Durango with the 4.7L engine, the ECM is typically located in the engine bay, mounted to the passenger-side firewall. It is a silver metal box with three large electrical connectors.
What information do you need from me to program the module?
We require your vehicle’s 17-digit VIN (Vehicle Identification Number) to ensure the programming is a perfect match for your Durango’s specific options and security system. You can typically find the VIN on your driver’s side dashboard (visible through the windshield) or on the driver’s door jamb sticker.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this part will resolve the issue. However, it’s crucial to ensure that the underlying cause of the codes is not a different failing component (like a sensor or wiring). This ECM will fix issues originating from the computer itself.
How do I find my current ECM’s part number?
The part number is printed on a white sticker on the ECM itself. You will need to locate the module on your vehicle to read the number. It will typically start with a ‘560’. Matching your part number to our compatibility list ensures a perfect fit.
