Throttle Body: Description and Operation
THROTTLE BODY ASSEMBLY
The throttle body functions similar to a conventional throttle body with the following exceptions:
-
An electric motor opens and closes the throttle valve.
-
The TAC module is an integral part of the throttle body assembly.
-
The throttle valve is spring loaded and the default position is slightly open.
-
There are 2 individual throttle position (TP) sensors integral to the TAC module cover.
The TP sensors are used to determine the throttle plate angle. The TP sensors provide the TAC module with a signal voltage proportional to throttle plate
movement. Both TP sensor signal voltages are low at closed throttle and increase as the throttle opens. TP sensor 1 determines the actual throttle valve
position. TP sensor 2 provides a backup value for TP sensor 1.
