I am not saying that I am not cut out to do my own work. After all, I have have done so for almost 35 years. I have rebuilt engines, replaced clutches, headgaskets, starters, done all kinds of brake jobs and many other things. I am only saying that my O2 sensor problem did not present on my code reader. I took a reading on the morning that I dropped the car off to the dealer. I still got the speed sensor fault. So I am confused. Also, the dealer did not get a speed sensor fault, but rather a faulty brake stop switch - which I had replaced at the start. He said that I must not have cleared it correctly. I think the dealer must use a slightly different code reader.

If I do get the CEL again, I guess I'll bring it back and say - hey, you promised this would fix the CEL.
