Before you reset the engine light, it’s crucial to understand why it turned on in the first place. The check engine light—also known as the malfunction indicator lamp (MIL)—is part of your Eurovan’s onboard diagnostics system (OBD2). When the engine control unit (ECU) detects a problem with the engine, emissions system, or related components, it stores a trouble code and triggers the light.
Common causes include:
- A loose or faulty gas cap
- Oxygen sensor failure
- Mass airflow sensor issues
- Catalytic converter problems
- Spark plug or ignition coil failure
- Exhaust gas recirculation (EGR) valve malfunction
- Evaporative emissions system leaks
Some of these issues are easy and inexpensive to fix—like tightening a gas cap—while others may require professional diagnosis and repair. Ignoring the light or resetting it without addressing the root cause can lead to reduced fuel efficiency, increased emissions, or even engine damage over time.
That’s why the first step in resetting the engine light is always to diagnose the problem. You can do this yourself with an OBD2 scanner or visit a mechanic for a professional scan.
Tools You’ll Need
To reset the engine light on your 2000 Eurovan, you’ll need a few basic tools. The exact tools depend on the method you choose, but here’s a list of what’s commonly used:
- OBD2 scanner: This is the most reliable tool for reading and clearing trouble codes. Look for a basic code reader (around $20–$50) or a more advanced scan tool with live data capabilities.
- Socket wrench or screwdriver: Needed if you plan to disconnect the battery.
- Safety gloves and glasses: Always protect yourself when working under the hood.
- Owner’s manual: Your Eurovan’s manual may have specific instructions or fuse box diagrams.
- Notebook or phone: To record trouble codes and repair notes.
Most of these items are inexpensive and widely available at auto parts stores or online. If you don’t own an OBD2 scanner, many auto parts stores (like AutoZone or O’Reilly) offer free code reading services.
Method 1: Using an OBD2 Scanner (Recommended)
The safest and most accurate way to reset the engine light on a 2000 Eurovan is by using an OBD2 scanner. This method allows you to read the trouble code, understand the issue, and clear the light—all without guessing.
Step 1: Locate the OBD2 Port
The OBD2 port on a 2000 Eurovan is typically located under the dashboard on the driver’s side. It’s a 16-pin connector, usually black or gray, and may be tucked behind a small panel or near the steering column.
To find it:
- Sit in the driver’s seat and look down near the pedals.
- Feel around for a rectangular connector with multiple pins.
- If you can’t see it, check your owner’s manual for a diagram.
Once you’ve located the port, make sure the area is clean and free of debris.
Step 2: Plug in the OBD2 Scanner
Turn off the ignition and insert the scanner’s plug into the OBD2 port. Make sure it’s fully seated and secure.
Next, turn the ignition to the “ON” position (but don’t start the engine). This powers up the scanner and allows it to communicate with the vehicle’s computer.
Step 3: Read the Trouble Codes
Follow the scanner’s on-screen instructions to retrieve the trouble codes. Most basic scanners will display a code like “P0420” or “P0171.”
Write down the code(s) and use the scanner’s built-in database or an online resource (like OBD-Codes.com) to interpret what they mean. For example:
- P0420: Catalyst system efficiency below threshold
- P0171: System too lean (bank 1)
- P0455: Large evaporative emission leak
This step is critical—don’t skip it. Knowing the code helps you determine whether the issue is something you can fix yourself or if you need professional help.
Step 4: Fix the Underlying Problem
Once you’ve identified the issue, take steps to resolve it. For example:
- If the code is P0455 (gas cap issue), tighten or replace the gas cap.
- If it’s P0133 (oxygen sensor), you may need to replace the sensor.
- If it’s P0300 (random misfire), check spark plugs, coils, or fuel injectors.
After making repairs, double-check all connections and ensure everything is properly installed.
Step 5: Clear the Codes and Reset the Light
With the scanner still connected and the ignition on, navigate to the “Clear Codes” or “Erase Codes” option on the menu. Confirm the action when prompted.
The scanner will send a signal to the ECU to delete the stored trouble codes and turn off the check engine light. You should see a confirmation message like “Codes Cleared” or “System Reset.”
Step 6: Verify the Reset
Turn off the ignition, wait 10–15 seconds, then restart the engine. The check engine light should remain off. If it comes back on immediately, the problem may not be fully resolved, or a new issue has been detected.
Drive the van for a short trip (10–15 minutes) to allow the ECU to complete its self-checks. If the light stays off, the reset was successful.
Method 2: Disconnecting the Battery
If you don’t have an OBD2 scanner, you can try resetting the engine light by disconnecting the battery. This method forces the ECU to reset by cutting power, but it’s less precise and may not work for all issues.
Step 1: Turn Off the Engine and Remove Keys
Make sure the engine is off and the keys are out of the ignition. This prevents any electrical surges or damage during the process.
Step 2: Locate the Battery
In the 2000 Eurovan, the battery is usually located under the hood on the driver’s side. Open the hood and secure it with the prop rod.
Step 3: Disconnect the Negative Terminal
Using a socket wrench or wrench, loosen the nut on the negative (black) battery terminal. Carefully remove the cable and tuck it away from the battery so it doesn’t accidentally reconnect.
Safety Tip: Always disconnect the negative terminal first to avoid short circuits.
Step 4: Wait 15–30 Minutes
Leave the battery disconnected for at least 15 minutes. This allows the ECU’s capacitors to discharge and the system to fully reset. Some experts recommend waiting up to 30 minutes for a complete reset.
Step 5: Reconnect the Battery
Reattach the negative terminal and tighten the nut securely. Make sure the connection is tight and corrosion-free.
Step 6: Start the Engine
Turn the ignition to “ON” and wait a few seconds, then start the engine. The check engine light may flash briefly but should turn off after a few seconds.
If the light remains off after driving for 10–15 minutes, the reset was successful. However, if it returns, the underlying issue hasn’t been fixed.
Method 3: Ignition Cycle Method
Some older vehicles, including the 2000 Eurovan, can reset the ECU using a specific ignition cycle pattern. This method doesn’t require tools but may not work on all models.
Step 1: Turn the Ignition to “ON” (Do Not Start)
Insert the key and turn it to the “ON” position. The dashboard lights should illuminate, but the engine should not start.
Step 2: Wait 3 Seconds
Leave the ignition in the “ON” position for exactly 3 seconds.
Step 3: Turn to “OFF” and Wait 3 Seconds
Turn the key back to “OFF” and wait another 3 seconds.
Step 4: Repeat the Cycle
Repeat steps 1–3 a total of 3 times. This completes the ignition cycle sequence.
Step 5: Start the Engine
On the fourth cycle, turn the key to “ON” and then start the engine. The ECU may reset, and the check engine light could turn off.
Note: This method is not guaranteed to work on all 2000 Eurovans, as it depends on the specific ECU programming. If the light remains on, use an OBD2 scanner or battery disconnect method instead.
Troubleshooting Common Issues
Even after resetting the engine light, you may encounter problems. Here’s how to handle common scenarios:
The Light Comes Back On Immediately
If the check engine light returns right after startup, the issue hasn’t been resolved. Use an OBD2 scanner to read the new code and address the root cause.
The Light Flashes While Driving
A flashing check engine light indicates a severe problem, such as a misfire that could damage the catalytic converter. Pull over safely and have the van towed to a mechanic.
The Reset Doesn’t Work
If none of the methods clear the light, the ECU may be storing a hard code that requires professional diagnosis. Visit a Volkswagen specialist or use a more advanced scan tool.
Battery Disconnect Causes Other Issues
Disconnecting the battery may reset radio presets, clock, or power window settings. Use your owner’s manual to restore these features.
Preventing Future Engine Light Issues
Once you’ve reset the engine light, take steps to prevent it from coming back:
- Perform regular maintenance: Follow the Eurovan’s service schedule for oil changes, spark plug replacements, and air filter checks.
- Use quality fuel and parts: Cheap fuel or aftermarket parts can trigger sensor errors.
- Check the gas cap: Always tighten it until it clicks three times after refueling.
