The 2015 Chevy Trax might show the check engine light if the gas cap is loose. Simply tighten the gas cap to turn off the light. Drive the car for at least 15-20 minutes at speeds over 25 mph. Excessive starting and stopping can stress the catalytic converter, so driving at highway speeds can help clear the check engine light. If you see a sudden drop in fuel economy, it's likely the O2 sensor needs replacing. This sensor keeps an eye on the oxygen levels in the exhaust, which is vital for the engine's fuel ratio. Generally, a check engine light could mean issues with the transmission, O2 sensors, or spark plugs. It's best to have the Trax checked by professionals to diagnose and fix any problems.
One possible cause for the check engine light coming on in a 2015 Chevy Trax is an improperly secured or damaged gas cap.
