Is Your Durango Giving You Headaches?
There’s nothing more frustrating than a vehicle you can’t rely on. If your 2002 Dodge Durango is suffering from erratic behavior like stalling at stoplights, rough idling, a persistent check engine light, or worse, a complete failure to start, the root cause is often a failing Engine Control Module (ECM). This isn’t just an inconvenience; it’s a critical issue that compromises your vehicle’s performance and safety. It’s time to stop guessing and install a solution that brings back the dependable performance you need.

An Expert’s Note on the 32-Tooth Tone Ring
From over 20 years in the shop, I’ve seen countless Durango owners chase a no-start issue after installing the wrong ECM. The 2002 4.7L engine with Federal emissions uses a very specific 32-tooth crankshaft tone ring. The ECM must be calibrated for this exact signal. Using a module designed for a different system (like the later 16-tooth ring) will result in a crank-no-start condition every single time. We verify that this 2002 Dodge Durango ECM 56040616AJ is correctly configured for your vehicle’s 32-tooth system, eliminating that potential nightmare and ensuring it works perfectly from the moment you plug it in.
