Restore Peak Performance to Your 4.7L V8
Is your 2001 Dodge Durango running rough, stalling unexpectedly, or showing a persistent check engine light? These are classic signs of a failing Engine Control Module (ECM). The ECM is the brain of your vehicle’s engine, managing everything from fuel delivery and ignition timing to emissions control and transmission shifting. When it starts to fail, it can cause a cascade of frustrating and potentially damaging problems. Don’t let a faulty computer keep your reliable SUV off the road. This direct-replacement engine computer is the definitive solution to get your Durango running like new again.
From the Diagnostic Bay
A customer brought in their 2001 Durango 4.7L with a complaint that stumped a few other shops. The vehicle would randomly stall at stoplights and had a very erratic idle. We scanned it and found a host of intermittent sensor codes—O2 sensors, MAP sensor, TPS—that didn’t seem related. After verifying the wiring harness and checking the sensors themselves, which were all fine, we focused on the ECM. By monitoring the live data stream, we saw sensor voltage readings dropping out randomly. This pointed directly to a failing processor within the ECM. We installed one of our pre-programmed modules, and the Durango immediately fired up with a smooth, stable idle. All the ghost codes vanished. It’s a textbook case of how a failing ECM can send you chasing phantom issues all over the engine bay.
Is Your 2001 Durango ECM Failing?
A faulty engine computer can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following symptoms, your ECM is a likely culprit. This module is the correct solution for these common issues.
- ✔ Check Engine Light: The check engine light is illuminated, often with communication-related trouble codes (U-codes) or multiple, seemingly unrelated sensor codes.
- ✔ Poor Engine Performance: Noticeable loss of power, hesitation during acceleration, and decreased fuel economy are common signs.
- ✔ Stalling or No-Start: The engine may stall intermittently, especially when warm, or may crank but refuse to start at all.
- ✔ Rough or Erratic Idle: The engine idles poorly, surging up and down or feeling like it’s about to shut off.
- ✔ Transmission Problems: The ECM also communicates with the transmission controller, so a faulty unit can cause harsh shifting, delayed engagement, or incorrect gear selection.
- ✔ Failed Emissions Test: An inability to pass a smog or emissions test is often directly linked to a malfunctioning engine computer.

Frequently Asked Questions
Do I need to have this computer programmed by a dealer?
No. This engine computer comes fully programmed to your vehicle’s VIN. It is a true plug-and-play solution, requiring no additional programming or flashing. Just install it and you’re ready to go.
Where is the ECM located on my 2001 Durango?
The ECM on a 2001 Dodge Durango with the 4.7L engine is located in the engine bay, mounted to the passenger side (RH) inner fender wall.
Will this fix my transmission shifting problems?
In many cases, yes. The ECM plays a vital role in controlling transmission functions. If the computer is faulty, it can cause erratic shifting. Replacing a bad ECM will often resolve these related transmission issues.
What information do you need from me to program it?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) to ensure the module is programmed correctly for your specific options and security system. You can typically find this on your dashboard, driver’s side door jamb, or on your vehicle’s registration.
Is this compatible with other part numbers?
Yes, this part is a direct replacement for 56040249AD and is also fully compatible with part numbers 56040249AA through 56040249AH.
