How to Reset Check Engine Light on a 1993 Accord

Dealing with a check engine light on your 1993 Honda Accord can be quite frustrating. However, resetting this light is a straightforward process that you can do yourself. In this guide, I’ll walk you through the steps to reset the check engine light on your Accord, ensuring that you can get back on the road with peace of mind.

What You’ll Need

Before you begin, gather the following items:

• Socket set (including a 10mm socket)
• Wrench
• Flashlight

Locating the Check Engine Light

The check engine light is typically located on the dashboard of your Accord. It’s a yellow light with an engine icon. Once you’ve located it, you can proceed to the next step.

Step-by-Step Guide to Resetting the Check Engine Light

Follow these steps to reset the check engine light on your 1993 Honda Accord:

1. Turn the ignition to the “ON” position without starting the engine.
2. Locate the diagnostic connector under the dashboard. This is usually found on the driver’s side, near the steering column.
3. Using your flashlight, locate the diagnostic connector and remove the cover.
4. Locate the two diagnostic pins on the connector. They are typically labeled “A” and “B” or “1” and “2” on the connector itself.
5. Using your 10mm socket, connect the two diagnostic pins together. This will ground the system and reset the check engine light.
6. Leave the pins connected for about 10 seconds to ensure the light resets properly.
7. After 10 seconds, disconnect the pins.
8. Turn the ignition off and then back on to start the engine.
9. Check the dashboard to ensure the check engine light is no longer illuminated.

What to Do If the Light Comes Back On

If the check engine light comes back on after you’ve reset it, there may be an underlying issue that needs to be addressed. Here are a few things to consider:

• Check for Error Codes: Use an OBD-II scanner to check for any error codes that may be causing the light to come back on.
• Inspect the Air Filter: A dirty or clogged air filter can cause the check engine light to illuminate.
• Check the Oxygen Sensor: A faulty oxygen sensor can trigger the check engine light.
• Inspect the Mass Airflow Sensor: A dirty or malfunctioning mass airflow sensor can also cause the light to come on.

Precautions

When working under the dashboard, always ensure that the engine is turned off and the vehicle is on a level surface. Additionally, be cautious when handling electrical components to avoid any accidents.
