03 Viper with YPVS trouble code

[powfinger]

i have an 03 Viper with the warning light flashing 7 tmes indicating a problem with the YPVS. THis occurs when I hit the throttle wide open and I hit in the 80 MPH range. The sled starts fine, idles, and runs great. I just get alarmed seeing the light flash out the code. It will flash through one time and then go out. Performance isn't affeced and the sled runs great. I have cleaned and adjusted the valves. I've also pulled the wire harness out to check for any rubbing, haven't seen any. Anybody have any advice?

Is the servo pulling the valves open smooth and steady with no studder?

lower idle to 900 rpms and watch close,

servo cable

check that none of the cable sheaths are pulled out at the servo end, if one is pulled out at the servo it will blink 7 times. Or if they are adjust too tight.

Thanks for all the responses guys. I do know the servo motor does move, it does seem like it is smooth. I will check to see if the one of the cables is pulled out of the housing like the diagram. I see alot of posts that say to check for rubbing and I thought that might be it. Sure runs like a raped ape even though the light blinks once in a while
