Engine (03.00)
Throttle Control (03.16)
Description
Motorised Throttles
The motorised throttle allows accurate control
of the inlet air.
A throttle position sensor (TPS) is incorporated
into the throttle unit. During normal engine
run, TPS signals are used by the PCM to
indicate power demand from the engine. If not
already at the desired position, the PCM will
drive the throttle motor to open or close the
throttle by the required amount.
At idle, the throttle butterfly is almost closed
and idle speed is controlled by small throttle
movements.
The throttle butterfly is spring loaded to fail in
the idle position. In the event of the throttle
butterfly spring failing, air flow will allow the
throttle butterflies to fail in the idle position.
No set-up procedure is required.
