Original Engine Management 9944 Throttle Position Sensor Throttle Position Sensors are calibrated to have same output characteristics throughout the rotational range of operation. Throttle Position Sensors maintain specific installed outputs to match OE rather than adjustable consolidated designs. Circuits are printed on flexible polyimide film or ceramic-based substrates for excellent dimensional stability preventing electrical performance drift. High-impact composite O.E.-style housing Special-design resistive element for extended life
