The throttle position sensor is attached to the car’s engine and sends information about the angle of the throttle plate to the vehicle’s computer. This data then adjusts the timing of the ignition and air/fuel mixture.
A 5-pin throttle position sensor has two wires each for the motor and the signal. It also has wires for the earth, hot power, and a signal. These wires are connected to the car’s computer.

- Hot Power Wire (5 Volt Reference voltage comes from the ECU)
The negative and positive wires of the throttle position sensor are also connected to the car’s computer. This allows the computer to control the vehicle’s throttle motor.
The signal wire is also used by the throttle position sensor to supply the necessary input to the car’s control system.
The power source for the throttle position sensor is provided by the car’s computer. Through this wire, the computer can provide the necessary voltage to the sensor. The last wire is used to supply the earth to the sensor.
