Check Engine Light
Understanding Your Honda Check Engine Light and Service Codes
Your Honda vehicle is equipped with a sophisticated monitoring system that keeps tabs on the health and condition of the most important components. To ensure lasting quality and longevity, it's important to understand the Honda Maintenance Minder reminders and know what to do if the check engine light ever comes on.
The system is designed to help you get ahead of any issues that may crop up so you can get the necessary service to avoid excessive wear and tear. At Jim White Honda, our Service Center is fully equipped to care for your Honda vehicle. When your check engine light comes on, you can give us a call for help determining the issue or confidently handle minor issues on your own by learning how to solve the problem and reset the warning lights.

Common Check Engine Light Problems & Fixes
The number one, most frequent cause for the engine light coming on is a loose gas cap. However, if checking the gas cap doesn't reset the light, then a check engine warning can indicate a wide range of problems that need your attention:
- Bad catalytic converter
- Something is wrong with the car battery
- Malfunctioning spark plugs or spark plug wires
- Possible Vacuum leak
- Bad oxygen sensor
- Issues with the mass air flow sensor
- Aftermarket parts may be causing a problem
