Throttle Body/TAC Assembly

Throttle Body/TAC Assembly


The throttle body for the TAC system is similar to a conventional throttle body with several exceptions. One exception being the use of a motor to control the throttle position instead of a mechanical cable. Another exception is the new design Throttle Position (TP) sensor. The TP sensor mounts on the side of the throttle body. The TP sensor is actually two individual TP sensors within one housing. Two separate signal, ground and reference circuits are used to connect the TP sensors and the TAC module. The TP sensor signal voltage increases as the throttle opens.
