Is Your 2001 Dodge Durango Running Poorly?
If you’re experiencing frustrating issues like stalling, misfires, a persistent check engine light, or a no-start condition with your 2001 Dodge Durango 4.7L, the root cause is often a failing Engine Control Module (ECM). As the central computer of your vehicle, the ECM manages everything from fuel injection and ignition timing to emissions control and transmission shifting. When it begins to fail, it can create a cascade of problems that are difficult to diagnose. This replacement engine computer, part number 56040250AC, is the definitive, hassle-free solution to restore your Durango’s performance and reliability.
From the Diagnostic Bay
We had a 2001 Durango 4.7L come into the shop that was driving the owner crazy. It would randomly stall at stoplights and occasionally wouldn’t start at all, but then fire up an hour later like nothing was wrong. The check engine light was on with a handful of random communication codes. The owner had already replaced the crank sensor and a few ignition coils with no luck. After hooking up our professional scan tool, we noticed the data stream from the ECM would intermittently drop out. A visual inspection of the computer revealed no obvious damage, but experience pointed us to an internal failure. We installed one of our pre-programmed ECMs, and the Durango immediately started and ran perfectly. The random stalling vanished, and all communication codes cleared. It’s a classic case where chasing individual sensors costs more time and money than addressing the core problem: a faulty computer.
Symptoms of a Failing Engine Computer
- ✔ Persistent Check Engine Light (CEL) that won’t clear or returns with various codes.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ A complete no-start condition where the engine cranks but won’t fire.
- ✔ Noticeable decrease in fuel economy.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Communication errors when trying to use an OBD-II scan tool.
- ✔ Misfire codes even after replacing spark plugs and ignition coils.

Frequently Asked Questions
Is this part truly “Plug and Play”?
Yes. We program the module with your vehicle’s specific VIN and mileage before shipping. This ensures it works with your existing keys and security system without any need for a trip to the dealership for additional programming.
Where is the ECM located on my 2001 Durango?
The engine computer on a 2001 Dodge Durango is typically located in the engine bay, mounted to the passenger side (RH) fender wall. It is a silver metal box with three large electrical connectors.
What information do you need to program the computer?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) and the current mileage. You can provide this information during the checkout process. The VIN is essential for correct programming.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this will resolve the issue. However, it’s important to ensure that the codes are not being caused by other failing components like sensors or wiring. This computer will solve problems originating from the module itself.
Do I need any special tools for installation?
No special tools are required. You will only need basic hand tools, such as a socket set, to unbolt the old computer and install the new one. The most important step is to disconnect the vehicle’s battery before you begin the swap.
