When this light appears, it’s essential to assess its urgency. Ignoring it can lead to more severe damage and costly repairs. If the light is flashing, this indicates a more critical issue, and you should stop driving immediately.

A loose gas cap is one of the simplest issues that can cause the check engine light to come on. Ensure the cap is tightened properly. If it’s damaged or cracked, consider replacing it.
2. Faulty Oxygen Sensors
The oxygen sensor measures the amount of unburned oxygen in the exhaust. If it fails, it can affect fuel economy and emissions. Replacing a faulty oxygen sensor is a common repair.
