Throttle Position Sensor Installation
Throttle Position Sensor (TPS) Circuit Diagram
The Throttle Position Sensor (TPS) is connected to the throttle valve shaft in the throttle body unit. The TPS is a potentiometer with one connection to
ground, and the other to the computer 5.0 volt reference source. A third wire from the computer is used to measure the output voltage from the TPS. As
the throttle angle changes (pressing down on accelerator pedal) so does the TPS voltage output. The computer monitors this voltage, calculates the
throttle valve angle, and uses this information, compared with information from other engine sensors, to determine engine load and regulate fuel
injection.
