well the other nite i was out doing some racing with the cutouts open and my ses light came on. i didnt think anything of it cuz it would sometimes come on when my cutouts were open and would just be the o2 sensor reading lean, no biggy. anyway it would usually go off when i capped them, but it was still on yesterday so i had autocrap put the obd II scanner on it to see what code it was throwing and it said crankshaft variable system unlearned, or something like that. wtf! ive never heard anything like that. has anyone else had this code before. it runs great, and isnt missing at all. ill have flyer look at it when he gets a chance, but is this serious or is this kind of a normal occurance?

 

- The DTC is P0335 CKP Correlation. Which is a relearn procedure done with a Tech II scan tool thru a GM dealer. I get this code intermitten when reprogramming computer alot. I'm lucky though, I,m service manager of a chevy store. If you can, get it relearned, if not it will not hurt your Truck, but can put you into small miss fire increments.

 

thanks, ive got a friend that has hp tuners and he said that he can probably do a crank relearn on it for me.
