ÿ 3. TPS2 output;
(a) Throttle valve control requires a throttle position sensor to detect throttle
position and condition. The voltage signal from the non-contact throttle
position sensor is sent to the engine control unit, which processes the
throttle position data in real time, taking into account operating
parameters.
