Honda civic 02 1.6vtec how to permanently lose warning light obd?

Disconnect battery doesn't work. Car seems to be fine

Car is clearly not fine. Might be running Ok for now but you do have a problem. The diagnostic code needs to be read to determine the code, the fault fixed and then the light goes off.

If the problem still exits, the light will come back on even after being cleared. You can't wish it away. Fix it or put black tape over the light.
