Is Your 2006 Caravan or Town & Country Running Rough?
If you’re dealing with frustrating issues like stalling, a persistent check engine light, poor fuel economy, or a vehicle that simply won’t start, the problem might be deeper than a simple sensor. The Engine Control Module (ECM), also known as the Powertrain Control Module (PCM), is the central computer of your vehicle. It manages everything from fuel delivery and spark timing to transmission shifting. When it fails, it can cause a wide range of confusing and intermittent problems that can be difficult to diagnose. Don’t let a faulty computer keep your reliable minivan off the road. This direct-fit replacement is the solution you need.
From the Diagnostic Bay
We had a 2006 Dodge Caravan come into the shop that had its owner completely stumped. He’d replaced the spark plugs, ignition coil, and even the crankshaft position sensor, but the van still had a terrible intermittent misfire and would stall at red lights. The check engine light would come on and off randomly. After hours of chasing ghosts, we hooked up our advanced scanner and monitored the live data from the ECM. We noticed the injector pulse width commands were erratic on two cylinders. A quick check of the wiring confirmed it was solid. The culprit? The ECM itself had failing injector drivers. We installed one of our pre-programmed modules, and the van ran like new. It’s a classic case where the vehicle’s brain, not a mechanical part, was the source of the headache.
Common Symptoms of a Failing 2006 Caravan Engine Computer
- ✔ Check Engine Light: The light is on, and you may have codes related to module communication, sensor circuits, or random misfires.
- ✔ Engine Stalling or Misfiring: The engine may stall unexpectedly, run rough, or hesitate during acceleration.
- ✔ No-Start Condition: The engine cranks but refuses to start, often due to a lack of spark or fuel command from the ECM.
- ✔ Poor Fuel Economy: A failing computer can’t efficiently manage the engine, leading to a noticeable drop in MPG.
- ✔ Inconsistent Shifting: The ECM plays a crucial role in transmission control, and a faulty one can cause harsh or erratic shifting.
- ✔ Communication Issues: Your mechanic’s diagnostic scanner may be unable to communicate with the engine computer.
The Plug-and-Play Solution
The biggest hurdle in replacing an engine computer has always been the expensive and time-consuming programming required at a dealership. Our process eliminates that completely. We take your vehicle’s unique Vehicle Identification Number (VIN) and current mileage and program this information directly into the module before it ships. When you receive it, the process is simple:
- Disconnect the Battery: Always start by disconnecting the negative battery terminal for safety.
- Locate and Remove the Old ECM: On the 2006 Caravan and Town & Country, the ECM is conveniently located on the driver’s side (LH) fender in the engine bay. Disconnect the wiring harnesses and unbolt the old unit.
- Install the New ECM: Bolt the new module in place and securely reconnect the wiring harnesses.
- Reconnect the Battery: Reattach the negative battery terminal.
That’s it. The vehicle will recognize the new, correctly programmed computer, and you’ll be ready to start the engine. No special tools, no trips to the dealer, and no hidden fees. This is the most straightforward way to restore your vehicle’s performance and reliability.

Frequently Asked Questions
Is this engine computer really plug and play?
Yes, absolutely. We program the module with your vehicle’s specific VIN and mileage before shipping. This ensures it communicates perfectly with your vehicle’s other systems right out of the box, with no additional programming required.
Where is the ECM located on my 2006 Caravan?
The Electronic Control Module (ECM) is located in the engine compartment, mounted to the driver’s side (LH) inner fender, near the battery.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then this part will resolve the issue. However, if the light is on due to another failing component (like an oxygen sensor or catalytic converter), that issue will still need to be addressed separately.
What information do you need from me to program it?
After you place your order, we will need your vehicle’s 17-digit Vehicle Identification Number (VIN) and the current mileage. This allows us to program the module correctly for your specific van.
Does this part fit both the 3.3L and 3.8L engines?
Yes, this engine computer is compatible with 2006 Dodge Caravan and Chrysler Town & Country models equipped with either the 3.3L V6 or the 3.8L V6 engine.
What is the difference between an ECM, ECU, and PCM?
These terms are often used interchangeably. ECM (Engine Control Module) and ECU (Engine Control Unit) typically refer to the computer managing the engine. PCM (Powertrain Control Module) is a more inclusive term for a module that controls both the engine and the transmission. For this vehicle, the terms all refer to this single control unit.
