About two months ago I got a p0139 code- "o2 sensor bank 1 sensor 2 slow response" I replaced it with oem quality ntk or ngk or whatever and a couple days ago cel came on again, same darn code. Been searching for info everywhere but cant seem to find anything to tell me why this would happen again. I didnt think o2 sensors went faulty that often and the same one seems suspicious. This is drivers side after the cat. Does this mean its time for new cats? |
