Is Your Jeep Compass, Patriot, or Dodge Caliber Running Rough?
Dealing with a vehicle that’s stalling, misfiring, or simply won’t start can be incredibly frustrating. If your 2007-2010 Jeep Compass, Patriot, or Dodge Caliber is displaying erratic behavior, the root cause is often the very brain of the operation: the Engine Control Module (ECM). This complex component is responsible for managing everything from fuel injection and ignition timing to emissions and transmission communication. When it begins to fail, it can create a cascade of confusing and costly problems.
Don’t let a faulty computer keep you off the road. This replacement Engine Control Module, part number 05150471AA, is the definitive solution to restore your vehicle’s performance and reliability. We take the guesswork and hassle out of the repair process. Each unit is professionally programmed to your vehicle’s specific VIN and mileage before it ships. This means it arrives at your door completely Plug & Play, ready for immediate installation without any need for expensive dealership programming or specialized tools.
From the Diagnostic Bay
We had a 2009 Dodge Caliber come in that was giving the owner fits. It had a random, intermittent misfire on cylinder 3 that would only happen after the engine was warm. The owner had already replaced the spark plug, coil pack, and fuel injector, but the problem persisted. A standard scan tool showed no hard codes, just a pending P0303. After hooking up a lab scope, we could see the injector driver signal from the ECM was dropping out sporadically. The issue wasn’t the injector itself, but the computer telling it what to do. A new, correctly programmed ECM like this one solved the problem instantly, saving the customer from chasing more phantom issues.
Common Symptoms of a Failing Engine Computer
- ✔ Check Engine Light: The most common sign, often with communication-related codes (U-codes) or specific circuit failure codes.
- ✔ Engine Stalling or Misfiring: The engine may stall for no reason, run rough, or hesitate during acceleration.
- ✔ No-Start Condition: You’ll hear the engine crank, but it will fail to start and run due to a lack of fuel or spark command from the ECM.
- ✔ Poor Fuel Economy: An inefficiently running engine, managed by a faulty ECM, will consume more fuel than usual.
- ✔ Shifting Problems: The ECM works with the Transmission Control Module (TCM). A failing ECM can cause harsh shifting or other automatic transmission issues.
- ✔ Inconsistent Performance: You might notice a sudden loss of power that returns just as mysteriously, indicating an internal ECM fault.

Frequently Asked Questions
Is this ECM truly plug and play?
Yes. We program the module with the VIN and mileage you provide. This ensures it communicates correctly with your vehicle’s other systems, including the security system, right out of the box. No further programming is required.
Where do I provide my VIN and mileage?
You will be prompted to enter your vehicle’s VIN and current mileage during the checkout process. Please ensure this information is accurate, as the programming is based entirely on the data you provide.
