THROTTLE BODY
DESCRIPTION
The Throttle Body is located on the intake manifold.
The Throttle Body controls the amount of air that
enters the intake manifold. Fuel does not enter the
intake manifold through the Throttle Body. Fuel is
sprayed into the manifold by the fuel injectors.
OPERATION
Filtered air from the air cleaner enters the intake manifold through the Throttle Body. A throttle valve (plate) is used
to supply air for idle and driving conditions.
The Throttle Position Sensor is part the Throttle Body. The Throttle Position Sensor signal is used by the PCM to
determine throttle position. The PCM controls the Electronic Throttle Control of the Throttle Body. The PCM monitors
the Accelerator Pedal Position Sensor to determine the amount of throttle opening.
