i have a s5 turbo 2, just did a FD UIM, TB, TPS swap, and now the throttle % is off, it gets to 100% with pedal half way down ive heard of people having this problem with a s4 cause of the narrow range but i have both full and narrow on the FD TPS so dont know why this is happening, before i did the swap it worked fine, do i gotta reset the s-afc or something im sure i have the wires on the tps hooked up right, so any info that anybody can give me will be appreciated, i searched but like i said people that were having this problem had s4's, is it maybe cause i dont have 1 of the grounds and 5 volt wires hooked up? the fd only has space for 1 of each unlike the s5 that has 2 of each

 

You got the wiring wrong.

The FD TPS runs 4 wires:
*common ground
*common power (+5VDC)
*narrow range signal output
*full range signal output

those are the 4 wires i have plugged in, i saw a post that showed the prongs on the fd tps, maybe it was wrong

with tab up

prong 1 groung
prong 2 full range
prong 3 5 volts
prong 4 narrow

is that correct?

 

is the narrow range wire the green wire coming off the s5 tps?

It looks like your info is wrong.

My S-AFC is doing the same thing. I have a s4, is there a way to fix it?

 

do a search to double check but i believe the people hook up the tps wire to the boost sensor

 

No, the S4 has a narrow-range TPS used only for the first part of the throttle travel.

 

ohhhh ok thought i broke something again on my s4 lol
