1. Check the wiring: Ensure the wiring to the O2 sensors is secure and not damaged.
2. Check the fuse: Check the fuse for the O2 sensors to ensure it is not blown.
3. Clear the code: You may need to clear the check engine light code using a scan tool or code reader.
4. Reset the ECU: Resetting the engine control unit (ECU) can clear the check engine light. To do this, disconnect the battery for a few minutes and then reconnect it.
5. Check for leaks: Check for any leaks in the exhaust system, as this can cause the check engine light to come on.
If the check engine light remains on after trying the above steps, it is recommended to have your vehicle diagnosed by a professional mechanic to determine the cause and ensure proper repair.
