My 2003 viper is flashing the caution light right when I start it. I need to find out what this means quickly. I did a search but can't find the code for 7 flashes. Please help me!!!!

Pull your servo cover off, take a few pic of how the cable sit on the cam...if you can pull any free play (cable wire) at the servo, then you have an issue...if not fire the sled up & burp the choke after you have it up to temp, watch the servo spin in & out...you should see no slack in the cables as it goes in & out...if you do have slack, then you have an issueviper17 said:It says its the YPVS.

a) pull threw- cable pulled threw the valve eye
b) broken cable
c) stuck open power valve(s)
I would pull each valve housing out with the valve to check condition...
Clean & adjust them to specs (lots of post on this subject, just do a search)
cheers

I checked the connections and they seemed fine. I started the sled again and the problem stopped. If it continues it will let you guys know, thanks a ton for the quick responses.
