How can i rest Nissan sunny 2005 check engine light?

To reset the check engine light on a 2005 Nissan Sunny, you can disconnect the car battery for about 10-15 minutes. This will clear the engine codes stored in the ECU and turn off the light. Alternatively, you can use an OBD-II scanner to erase the codes directly. However, if the light reappears, it's important to diagnose and address the underlying issue causing it.
