Causes of CEL Issues:

Oxygen Sensor Failures: A common cause of the Check Engine Light in the Toyota Camry is a failing oxygen sensor. A malfunctioning oxygen sensor can lead to poor fuel efficiency and engine performance issues.

MAF Sensor o r EGR Valve Issues: A clogged EGR valve o r a malfunctioning MAF sensor Mass Air Flow sensor can also trigger the CEL. Both of these components are essential for managing exhaust gases and airflow to the engine.

Diagnosing CEL Issues:

OBD-II Scanner: Owners can use an OBD-II scanner to diagnose the issue. The scanner will pull error codes, indicating the specific sensor o r system that is malfunctioning, allowing for easier troubleshooting.
