have you checked wiring at app sensor connector, and between the throttle body connector
edit, the app connetor has 6 wires on it, 3 for each sensor,
for sensor 1
wh-bk is 5v ref
d-bu is signal
bn is low ref
sensor 2
tn is 5v ref
L-bl is signal
pu is low ref
for on the Tac module(throttle body) pins 1-3, 11-13 same colors
i dont know if this is correct for a 05, as this is for 07
