I have a 04 gtp and some codes have thrown.
P0120 TPS/pedal position sensor a circuit malfunction
P0220 TPS/pedal pos. sensor switch (a and b) circuit malfunction
P1516 Command TAC

I have bought a new throttle body (L32), and a new throttle position sensor on the pedal and neither did it for me.

I do have a scan tool so i am able to do a bit on it. It is a Creader V (Launch)

Can anyone please direct me in ways to fix or troubleshoot the problem?
Thanks for any replies.
