i would like to replace this as a precaution.. i just bought a used envoy with 103000 miles on it. do i have to do a relearn on it? i looked thru tech2win and it does say you have to but it says rev engine to spacific rpm.. can anyone expound on this procedure. can you just do it in park or do you have to be driving around?

Cam sensor doesn't need a relearn. Crank sensor on the other hand needs a CASE relearn which can be done by the dealer or someone with a high end scan tool.
