Is Your 2000 Minivan Running Rough? It Could Be the ECM.
If you’re experiencing frustrating and unpredictable issues with your 2000 Dodge Caravan, Plymouth Voyager, or Chrysler Town & Country, a failing Engine Control Module (ECM) is a very common culprit. This component is the central brain of your vehicle’s powertrain, responsible for managing everything from fuel mixture and ignition timing to transmission shifting and emissions control. When it starts to fail, it can create a cascade of problems that are often misdiagnosed, leading to wasted time and money on unnecessary repairs.
From the Diagnostic Bay
We had a 2000 Dodge Caravan with the 3.3L Flex Fuel engine come into the shop with an intermittent no-start condition and a complaint of stalling at stoplights. The owner had already replaced the crank sensor and the fuel pump based on advice from a forum. Using a professional scan tool, we noticed that the ECM would intermittently lose communication with the rest of the vehicle’s modules. We performed a wiggle test on the main harness connector at the ECM and were able to duplicate the stalling. Before condemning the module, we verified it had solid power and ground connections. With those confirmed, it was clear the internal circuitry of the original computer was failing. A replacement, pre-programmed ECM like this one resolved all the issues, and the van was back to being a reliable family hauler.
The Direct Solution for Your 3.3L Flex Fuel Minivan
This replacement engine computer is the definitive solution for restoring your vehicle’s performance and reliability. We take the guesswork and hassle out of the repair process. Unlike a generic part from a salvage yard, this unit is meticulously prepared for your specific vehicle. By providing us with your Vehicle Identification Number (VIN) and current mileage during checkout, we flash the module with your vehicleās exact factory software and security information. This means the part you receive is 100% plug-and-play, requiring no additional programming or expensive trips to the dealership.
Common Symptoms of a Failing 2000 Voyager Engine Computer
- ā Check Engine Light is on with communication-related fault codes (e.g., U-codes).
- ā Vehicle refuses to start or has a crank-no-start condition.
- ā Intermittent stalling, especially when the engine is warm.
- ā Rough or erratic idling and poor engine performance.
- ā Noticeable decrease in fuel economy.
- ā Harsh or incorrect automatic transmission shifting.
- ā Issues with other electronic systems, as the ECM communicates with multiple modules.
Installation and Compatibility
Replacing the ECM on these minivans is a straightforward job for a DIYer with basic tools. The module is located on the driver’s side (LH) fender, inside the engine bay. Simply disconnect the negative battery terminal, unplug the three main electrical connectors, and unbolt the module from its bracket. Installation is the reverse of removal. Because this unit comes pre-programmed, once it’s installed and the battery is reconnected, you can start the vehicle and drive away.
This module is a direct replacement for part numbers 04727280AB and 05017591AA and is specifically for the following vehicles:
- 2000 Chrysler Town & Country with 3.3L Flex Fuel Vehicle (FFV) engine
- 2000 Plymouth Voyager with 3.3L Flex Fuel Vehicle (FFV) engine
- 2000 Dodge Caravan with 3.3L Flex Fuel Vehicle (FFV) engine
Frequently Asked Questions
Do I need to have this engine computer programmed?
No. This module comes fully programmed to your vehicle’s specific VIN and mileage. It is a true plug-and-play solution, ready for installation right out of the box with no dealer visit required.
Where is the ECM located on my 2000 Dodge Caravan?
The Engine Control Module is located in the engine bay, bolted to the driver’s side (LH) inner fender well, near the battery.
What information do you need from me to program the module?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) and the current mileage. You can provide this information during the checkout process.
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 there are other underlying problems with sensors or wiring in your vehicle, the light may remain on. It is always best to have the codes scanned to understand the root cause of the problem.
Is this compatible with part number 05017591AA?
Yes, this ECM is a fully compatible and interchangeable replacement for part numbers 04727280AB and 05017591AA, covering the same applications.
What is the difference between an ECM, ECU, and PCM?
The terms are often used interchangeably. ECM (Engine Control Module) and ECU (Engine Control Unit) typically refer to the same component. PCM (Powertrain Control Module) is a more integrated unit that controls both the engine and the transmission. For this specific 2000 minivan application, this part functions as the brain for the entire powertrain.
