Interested in knowing where your throttle is? Well, your engine does. And it needs to know precisely where it's positioned to help it achieve better performance. So how is it able to find out exactly where the throttle is? It relies on the use of a throttle position sensor. This device determines the exact position of your car's throttle and relays the information to the engine control unit or ECU in the form of sensor signals. These signals are increasing or decreasing voltages that are produced depending on how much power is required by the driver from the engine. What the driver needs is determined by how much pressure is applied to the gas pedal. Through this process, the ECU determines what needs to be done to achieve optimum engine performance while the vehicle is on the road. Since it does a lot for you and your vehicle, the throttle position sensor is made from premium materials to keep it from breaking down quickly. It's also designed to match the specifications of your vehicle so you won't have to waste time making unnecessary modifications to it. So if you want your car to achieve stellar performance, make sure it knows where its throttle is by installing a throttle position sensor. That way, its ECU will know what to do the moment you push the pedal to the metal.
