When your check engine light is on, don’t panic – it may not be as serious of an issue as you think. This light turns on when the internal diagnostic system has noticed something is wrong. It’s a good idea to understand this computer and some of the reasons why it may indicate your vehicle has an issue. Safe Auto Service in Meriden, CT, offers some insight into what your check engine light may be trying to tell you and what to do when it goes off.

What Does the Check Engine Light Really Mean?

Many vehicles today use On-Board Diagnostics (OBD) II testing, a vehicle computer that lights up the check engine light when it finds something wrong. This could indicate a plethora of things, from a loose gas cap to a malfunctioning mass air flow sensor or catalytic converter. These are some of the top reasons why check engine lights turn on, along with emission system issues, brake problems, or manufacturer-specific complications. 

What should you do when the check engine light goes on? Start by using an OBD II connector to convert the code turning the light on into an issue you understand. These little tools plug into your dashboard and tell you what problem the light is indicating. Then, you can decide to address the issue yourself or head to a mechanic for professional help.

Following regular maintenance routines, like getting oil changes and keeping your vehicle in good shape, will prevent the check engine light from turning on. If it does signal that you have a problem, call Safe Auto Service at (203) 237-4311 to schedule a tuneup.
