Hello, I drive an ep3 CTR with i/h/e. I'm sorry but I don't know the serial of my K-pro...
to get to the point, a few days ago i got an error code, forgot the number, but it said Air fuel sensor slow response.
then last night it read Air fuel sensor no activity detected. The CEL only goes on when the car gets warm. Air fuel sensor is the 02 sensor, isn't it? Is it a bad sensor or is it possibly something else? I've changed the sensor a couple of months ago... Suggestions/ solutions appreciated
