Is your 2004 Dodge Durango giving you headaches with a persistent check engine light, rough idling, or a frustrating no-start condition? These are common signs of a failing Engine Control Module (ECM), the brain of your vehicle’s engine. Don’t let a faulty computer keep your reliable SUV off the road. This professionally programmed 2004 Dodge Durango 4.7L ECM is the direct, hassle-free solution to get you back behind the wheel with confidence.

A failing ECM can cause a wide range of confusing and intermittent issues. If you’re experiencing any of the following, this module is the definitive fix:

- Apparent sensor failures even after replacing the sensors
Instead of guessing and replacing part after part, address the root cause. This replacement engine computer is programmed specifically to your vehicle’s VIN, ensuring it works seamlessly with your existing keys and systems right out of the box.
