The check engine light in your Honda can be a bit alarming when it pops up on the dashboard. It can indicate everything from a minor issue like a loose gas cap to a more serious problem that may require professional attention. Regardless of the cause, there are a few ways to reset the check engine light on your Honda once the issue has been addressed.
If you're unsure about the cause of the check engine light or need assistance in diagnosing it, Glakes Honda West offers expert services to help you get to the bottom of the problem.
- Turn Off Your Vehicle and Wait
Sometimes, a simple issue can cause the check engine light to illuminate, and it may reset on its own after a short period. If the issue has been fixed (for example, if you’ve tightened the gas cap), the light may turn off after driving for a few miles. If the light doesn’t go off after a day or so, you might need to take further action.
While waiting for the light to reset naturally might work in some cases, it's always best to ensure there are no lingering issues with your Honda’s engine. If the light remains on, it’s time to try other methods to reset it.
- Disconnect the Battery
One of the most common ways to reset the check engine light in your Honda is by disconnecting the vehicle’s battery. Here’s how to do it:
- Turn off your vehicle and open the hood.
- Locate the battery and use a wrench to loosen the negative terminal (usually marked with a minus sign).
- Disconnect the negative terminal and leave it off for about 15-30 minutes. This will reset the vehicle’s computer system and clear the check engine light.
- Reconnect the terminal, tighten it, and close the hood.
- Start the vehicle to see if the light has turned off.
This method can reset the vehicle's ECU (engine control unit), which often clears the check engine light, but keep in mind that it may not solve the underlying issue.
- Use an OBD-II Scanner
If you're comfortable with using diagnostic tools, you can use an OBD-II (On-Board Diagnostics) scanner to reset the check engine light. These scanners are available for purchase or can be found at most auto parts stores. Many of these stores also offer free scanning services. Here’s how to use an OBD-II scanner:
- Plug the OBD-II scanner into the diagnostic port under your Honda’s dashboard, usually near the driver's seat or beneath the steering wheel.
- Turn on the ignition without starting the engine.
- Follow the scanner’s prompts to read the diagnostic codes. The scanner will display the issue causing the check engine light to turn on.
- Clear the codes: Once you’ve reviewed the issue, the scanner will have an option to clear or reset the codes. Select that option to reset the check engine light.
- Turn off the ignition and unplug the scanner.
Using an OBD-II scanner allows you to diagnose the issue as well as reset the check engine light. However, keep in mind that the light may turn back on if the problem hasn’t been properly addressed.
- Visit a Professional Mechanic
If none of the above methods work, or if the check engine light returns after being reset, it’s important to have your Honda professionally diagnosed. Glakes Honda West offers diagnostic services to help identify and resolve the issue. A certified technician can perform a thorough inspection, run diagnostics, and ensure that the issue is fixed before resetting the light.
In some cases, the check engine light may be triggered by a more serious issue, such as an engine misfire, catalytic converter failure, or a faulty sensor. A professional mechanic will have the tools and expertise to accurately identify the problem and recommend the appropriate repairs.
If you’re unsure about why the check engine light has come on in your Honda or if you need help resetting it, don’t hesitate to seek professional assistance. Visit Glakes Honda West for expert advice, diagnostic services, and repairs to ensure your vehicle is running at its best.
