Our Throttle Position sensors are made by implementing a proprietary sliding contact technology, based on multiple precious metal contacts riding on polymer thick film resisters to offer a longer working life than competitor sensors on the market today. Each of our sensors is provided with integral rotor bearings and return springs which allow for easy installation when compared to the spring-less designs currently available in the aftermarket, which rely on worn throttle body bearings and return springs to set the correct output voltage. Our sensors maintain specific installed outputs to match the OE rather than using adjustable, consolidated designs. Engine management systems require reliable connections in order for sensors to reach the optimum performance level. We manufacture our sensors to ensure that both external and internal connections remain reliable in order to maintain these requirements through the product life. Each sensor that we offer endures rigorous end of line testing which involves many thousands of data points to validate output voltages and to ensure that each part meets linearity specifications that are expected by the engine management system in your vehicle.
