Check Engine Light Repair in Big Rapids, MI
The check engine light, also known as the malfunction indicator lamp (MIL), is part of your vehicle’s onboard diagnostic system. It can illuminate for a wide variety of reasons, from a simple loose gas cap to more serious issues with sensors, catalytic converters, or emission systems.
If your check engine light comes on, it’s best to schedule a diagnostic as soon as possible. While some causes are minor, others can worsen with continued driving. Avoid long trips until the problem is diagnosed and resolved, and bring your vehicle to a certified shop, such as Johnson's Automotive.
When you arrive, our technicians will begin by connecting a professional-grade scan tool to your vehicle’s onboard computer. This allows us to retrieve the trouble codes (also known as “DTCs” or diagnostic trouble codes) that point toward the affected area(s). For example, a code such as P0302 may indicate a misfire in cylinder 2, while P0420 could suggest a catalytic converter efficiency issue. These codes give us a roadmap to investigate the root cause, not just to clear the warning light temporarily.
