February 9, 200620 yr I should know this, but shouldn't my O2 LED be flashing when the engine is running? I thought that it would indicate the sensor is doing it's thing. Not talking about codes and such, that works fine. Just under normal conditiopns the light is not lit. Thanks, Jon
February 9, 200620 yr I know this won't help much, but my o2 LED has never blinked for me...off, on or running. Even if it was good or bad.
