Throttle Position Sensor (TPS)

TPS is mounted on throttle body and monitors opening angle of throttle valve. Sensor varies its output voltage according to angle of throttle blade opening. SBEC uses this information and other sensor inputs to adjust air/fuel ratio. If SBEC senses wide open throttle (WOT) position during cranking, it assumes engine is flooded and turns off fuel injectors until throttle is released.
