Yes, several sensors can trigger the check engine light, including the oxygen sensor, mass airflow sensor, and throttle position sensor. Issues with the catalytic converter or the engine temperature sensor can also cause the light to activate. When these sensors detect abnormalities in engine performance or emissions, they send signals to the vehicle's onboard diagnostics system, which then illuminates the check engine light. It's essential to diagnose the specific cause using an OBD-II scanner for accurate troubleshooting.
