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.
