I have heard you can extend the life of your sensor by removing it and using a torch to heat the end and burn away the residue that may be causing the fault. I haven't tried this though. I have just used a code reader to erase the code and it works for a while. I have one now that's acting up. I erased the code a couple of months ago and it hasn't come back yet. However, I don't drive that much now being retired. As far as clearance goes - you might have to get creative and try a 6pt box wrench or something.

Thanks. Did do it completely from the bottom?
