P1518
 

I have a 2006 silverado with a cam. I had a p0641, p0522, and p0101 I checked all sensors and grounds gave up and took it to the shop they checked all sensors and ground and they swapped computers. Now I'm getting a p1518 reduced power and battery system not charging even though it is charging. I'm running an computer out of 03. Before I swapped computer it barely ran and would stall out now it will idle all around but ass soon as hit the gas it throws the p1518. Any help would be appreciated. And my tune has been copied to that computer

P1518 is not a valid code for a 06 OS. It is a valid code for a 03 OS. That says the shop you took it to doesn't know what they are doing and are trying to run a 06 ETC Pedal/TAC/TB on a 03 OS. You can't do that.

They asked me if I had a computer I could use to try and my tuner can tune 03s without buying credits so I figured 03/06 computer would work.... so would I have to get an 06 computer or will anyou other years work?

Or could I takeep the parts of the 03 parts truck and put them on my 06?
