The functions of today’s fuel injected engines rely completely on a powertrain control module (PCM) and its associated sensors, of which there are many. Fuel has the ability to adapt to altitude, temperature, humidity, and load while maintaining a constant fuel ratio of 14.7:1.

In order for the PCM to prepare fuel flow strategies, it uses sensors to determine the demand on the engine and its operating environment.

The throttle position sensor (TPS) is a potentiometer located on the throttle body and attached to the throttle plate opposite the throttle linkage. It has three wires: battery voltage, 5-volt reference, and a signal wire. Its purpose is to signal to the powertrain control module (PCM) the amount and speed of the throttle opening. This is an indication as to the demand placed on the engine at any given time.
