My OXS lamp has been on as long as I can remember. I had the sensor replaced but the shop never turned off the light as they did not know how. I was told there was a switch under the drivers side wheel well but I pressed it and it did nothing. Is there any way to turn this thing off? I have my emissions test coming up and they will surely fail me if the light is on.
Thanks.
