The check engine light and trac off light on a Toyota Corolla can come on for various reasons. One common cause is a loose or improperly tightened gas cap. If the gas cap is not properly secured, it can trigger the check engine light and trac off light to illuminate. Simply tightening the gas cap may resolve the issue.
However, there can be other underlying issues that may require further diagnosis and repair. If the check engine light accompanies the trac off light, it may indicate a deeper malfunction within the traction control system or another crucial safety system. In such cases, it is recommended to have the vehicle diagnosed by a professional technician to identify and address the specific problem.
It’s important to note that the information provided is based on general knowledge and common causes. For a more accurate diagnosis and resolution, it is always best to consult with a qualified mechanic or bring the vehicle to a Toyota service department for further inspection.
I hope this helps! Let me know if you have any other questions.
