Re: Check engine light = P0133 code
I had the same problem with my '01 C5 around the same mileage. I don't have any idea why it gave me the code. I cleared the codes, and had it try to come on about two or three more times, and then...for no reason it stopped.
You may get some different advice from some folks here on the forum that tell you to do otherwise. But at least in the meantime, if you clear the codes, you don't have to look at that damn yellow light.
