Expert Check Engine Diagnostics, Repairs, and Maintenance
The check engine light is triggered by the output from your onboard computer diagnostic system. Its single purpose is to inform you of situations that need to be addressed. Your vehicle’s problem could be a loose gas cap or a bad spark plug. It could be something more complicated like a malfunctioning catalytic converter.
When your check engine display lights up, it always involves a problem that reduces your car’s performance, lowers your fuel efficiency or increases toxic emissions.
