Is Your 2006 Minivan Acting Up? It Could Be the Engine Computer.
Driving a 2006 Dodge Caravan or Chrysler Town & Country should be a reliable experience, but when the brain of the engine—the Engine Control Module (ECM)—starts to fail, it can cause a cascade of confusing and frustrating problems. You might be dealing with an engine that won’t start, stalls unexpectedly, or has a persistent Check Engine Light that no amount of part-swapping seems to fix. These issues can make your vehicle unreliable and unsafe. This replacement engine computer is the definitive solution to restore your minivan’s performance and dependability.
From the Diagnostic Bay
We had a 2006 Town & Country with the 3.8L V6 come into the shop with a classic intermittent stalling issue. The owner had already replaced the spark plugs, ignition coil, and even the fuel pump. The van would run perfectly for days, then suddenly die at a stoplight and refuse to restart for 20 minutes. Scans showed no consistent codes, just a few random communication errors. After checking all the wiring and grounds, we suspected the ECM. We installed one of our pre-programmed units, and the problem vanished instantly. The thermal stress on the old computer’s internal circuits was causing it to fail only when it reached a certain temperature, a common failure mode that can be incredibly difficult to diagnose without a known-good part to test with.
Common Symptoms of a Failing 2006 Caravan Engine Computer
A faulty ECM can manifest in various ways. If you’re experiencing any of the following, your engine computer is a likely culprit:
- ✔ Check Engine Light: The light is on, and you may have codes related to sensor circuits (e.g., P0107, P0340), injector control, or internal processor failure.
- ✔ Engine Stalling or Misfiring: The engine may stall for no reason, either while driving or at idle. You might also notice rough running or hesitation during acceleration.
- ✔ No-Start Condition: The engine cranks but refuses to start. This can be caused by the ECM failing to control the fuel injectors or ignition coil.
- ✔ Poor Fuel Economy: If the computer isn’t managing the engine’s air-fuel mixture correctly, you’ll see a noticeable drop in MPG.
- ✔ Inconsistent Transmission Shifting: The ECM works with the transmission controller. A faulty module can lead to harsh shifts, delayed engagement, or getting stuck in a gear.
- ✔ Apparent Failure of Multiple Sensors: If you suddenly have error codes for several unrelated sensors, it’s often the computer itself that is failing, not the sensors.
The Plug-and-Play Solution You Need
Forget expensive dealership visits and the hassle of towing your vehicle for programming. This module is the straightforward, DIY-friendly fix. We handle all the complex programming in-house before the unit ever ships. Simply provide us with your vehicle’s Vehicle Identification Number (VIN) and current mileage during checkout. Our technicians will flash the module with your vehicle’s exact software and security information. When it arrives, the installation is simple:
- Disconnect the Battery: Always start by disconnecting the negative battery terminal for safety.
- Locate the Old ECM: On the 2006 Caravan and Town & Country, the ECM is located on the driver’s side (LH) fender in the engine bay.
- Swap the Modules: Carefully unplug the electrical connectors and unbolt the old module. Bolt the new one in its place and securely reconnect the connectors.
- Reconnect the Battery: Reattach the negative battery terminal.
That’s it. The vehicle will start and run correctly with no additional programming or dealer intervention required. This is a direct-fit replacement for your original 2006 Caravan Engine Computer, designed to restore factory performance.

Frequently Asked Questions
Is this engine computer really plug-and-play?
Yes, absolutely. We program the unit with your vehicle’s specific VIN and mileage before shipping. This ensures it communicates correctly with all other modules in your vehicle, like the instrument cluster and anti-theft system, right out of the box. No further programming is needed.
Where is the ECM located on my 2006 Caravan or Town & Country?
The Electronic Control Module (ECM) is located in the engine compartment on the driver’s side, mounted to the fender well, typically near the battery and fuse box.
What information do you need from me to program it?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) and the current mileage. You can typically find the VIN on your driver’s side dashboard (visible through the windshield) or on your vehicle’s registration or insurance card.
How can I be sure the ECM is the actual problem?
While the symptoms listed are strong indicators, it’s always best to have a qualified mechanic perform a thorough diagnosis. This includes checking for proper power and ground at the ECM connector and ruling out wiring issues. However, if multiple unrelated sensor codes are present or the vehicle has an intermittent no-start condition that isn’t related to the battery or starter, the ECM is the most likely cause.
Will this fix my vehicle’s emissions test failure?
If the failure is due to a faulty ECM causing a Check Engine Light or incorrect engine parameters, then yes, replacing it with our correctly programmed module will resolve the issue and allow the vehicle’s readiness monitors to set properly for an emissions test.
