The fear of the unknown (or the cost of the unknown) can be just as stressful.

When the light turns on, the ECM stores an engine code or “trouble code” in its memory that identifies as the issue, whether it's a sensor or a failing engine part. This code is read with an electronic scan tool that is used by our Toyota auto repair technicians at Coggin Toyota at the Avenues.

If your check engine light turns on quickly after you put gas in your 2018 Toyota Highlander, initial thing you should check is to make fearless the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.

A faulty sensor can not only affect your miles per gallon, but it can cause damage to your catalytic converter and your 2018 Toyota Highlander's spark plugs.

A bad O2 sensor can also cause a car to fail an emissions test.
