I just installed a tps 228r cam into my 99 ls1 t/a while i had it apart for a complete rebuild. it ran rich down low and lean up top before the tune and the ses light was on but i didnt run any codes or anything, i figured it just needed a tune. well i got me a tune yesterday and everything was perfect. i put about 100 miles on it and today the ses light came back on. i ran the code and it shows bank 2 knock sensor low and high voltage? what the heck?

im having the same problem with my heads cam car. i think it may be a faulty knock sensor. i have knock sensor 1 low voltage only though

mine says low voltage, my bad. mt mechanic replaced one of the ks about a month ago but idk which one. think it might be in the tune?
