Check Engine Light On? Heres What To Do

The check engine light, also known as the malfunction indicator lamp, comes on to alert drivers of an emission system issue. When the light comes on, it stores a diagnostic trouble code (DTC) in the engine’s computer. The DTC is used by mechanics as a path of diagnosis, helping them to figure out how to fix the issue.

If the check engine light comes on solely because of an emissions issue, you should still be able to drive your car without complaints.

There will be no other prevailing issues other than the light.

However, sometimes the check engine light is on, and you may notice your car is driving poorly and has low power. At this stage, the vehicle goes into reduced power mode, or ‘Limp Mode’ because the engine computer lacks enough data to run the engine efficiently. The remote start system might also stop working with a check engine light that comes on.

If your check engine light is blinking, you are damaging your catalytic converter, and you should pull over and shut your car down as soon as possible. It is best to call a tow service to save it from failure and hopefully keep that catalytic converter working for a long time! .
