Is Your 1998 Minivan Running Rough?
If you’re experiencing frustrating issues like stalling, erratic idling, a persistent check engine light, or even a no-start condition with your 1998 Dodge Caravan, Chrysler Town & Country, or Plymouth Voyager, the root cause is often a failing Engine Control Module (ECM). As the central computer of your vehicle, the ECM is responsible for managing everything from fuel mixture and ignition timing to transmission shifting. When it starts to fail, it can create a cascade of problems that are often misdiagnosed. This direct-fit, pre-programmed 1998 Caravan Engine Computer is the definitive solution to restore your vehicle’s reliability and performance.
We had a 1998 Town & Country come into the shop that was driving its owner crazy. It would stall unpredictably at red lights and sometimes refuse to restart for 10-15 minutes. The owner had already replaced the crank sensor and the fuel pump based on other shops’ advice, with no improvement. When we hooked up our advanced scanner, we noticed intermittent communication drops with the engine computer. On a hunch, we monitored the data stream while applying heat to the ECM with a heat gun, simulating a hot engine bay. Sure enough, the data went haywire and the engine stalled. The original ECM’s internal circuits were failing when they got hot. We installed one of our pre-programmed modules, and the van ran perfectly. It’s a classic example of how a failing ECM can mimic other component failures, making a direct replacement the only true fix.
Common Symptoms of a Failing ECM
- ✔ Unexplained Check Engine Light (CEL) that may appear and disappear.
- ✔ Engine stalling, sputtering, or misfiring, especially when warm.
- ✔ A noticeable drop in fuel economy.
- ✔ Rough or unstable engine idle.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Complete failure to start the engine, even with a good battery and starter.
- ✔ Inability for diagnostic tools to communicate with the module.
Why Choose a Pre-Programmed 1998 Caravan Engine Computer?
The engine computer in your minivan is not a one-size-fits-all part. It contains specific software tailored to your vehicle’s Vehicle Identification Number (VIN), including details about its emissions equipment, transmission, and security system (if applicable). This unit eliminates the guesswork and costly trips to the dealership. We flash the module with your vehicle’s exact VIN and mileage before it ships, making the installation process straightforward. This is a true Plug & Play solution. Once installed, the vehicle will recognize the module as its own, allowing you to get back on the road without any additional programming or key relearning procedures.
Guaranteed Fitment and Compatibility
This module is a direct replacement for your 1998 Dodge Caravan, Chrysler Town & Country, or Plymouth Voyager equipped with the 3.3L (6-201) gasoline, low-emissions engine. It is fully compatible with a range of original part numbers, ensuring a perfect match for your vehicle. Please verify your original part number against the list below to confirm compatibility.

Located on the driver’s side (LH) fender, swapping out the old module is a job most DIY mechanics can handle with basic tools. Simply disconnect the battery, unplug the electrical connectors from the old unit, unbolt it, and install the new one in its place. Reconnect everything, and you’re ready to go.
Frequently Asked Questions
What information do you need to program this ECM?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) and the current mileage. This ensures we can load the correct factory software and settings for your specific minivan, making the installation seamless.
Is this module truly “Plug and Play”?
Yes. Because we program the module to your VIN before shipping, it requires no additional programming or dealer intervention. Once you install it, your vehicle’s systems will recognize it, and you can start the engine and drive away.
Where is the ECM located on my 1998 Caravan or Town & Country?
The Electronic Control Module is typically located in the engine bay, mounted to the driver’s side (LH) inner fender well, near the battery.
Will this fix my transmission shifting problems?
In many cases, yes. The ECM plays a crucial role in controlling the automatic transmission’s shift points. If your current module is faulty, it can cause harsh shifting, delayed engagement, or other transmission-related symptoms. A new, correctly functioning ECM often resolves these issues.
Do I need to send my old computer back?
Please check the purchasing terms for information regarding a core deposit. In many cases, returning the old unit (the “core”) is required to receive a refund of the core deposit paid at the time of purchase.
