Throttle Body: Description and Operation
Throttle Body
DESCRIPTION
The throttle body has a throttle plate to control the amount of air delivered to the engine. The TP sensor, MAF sensor, and IAC valve are also
mounted on the throttle body.
Vacuum ports located behind the throttle plate provide the vacuum signals needed by various components. Engine coolant is directed through a
coolant cavity in the throttle body to warm the throttle valve and prevent icing.
