But how does the PCM know the amount of fuel to inject This is the main function of the oxygen sensors The oxygen sensors generate a small electric current with voltage varying from around 0 1 to 0 95 volts Less voltage indicates a lean condition and more voltage indicates a rich condition They measure the difference between the amount of oxygen in the exhaust and the amount of oxygen in the atmosphere Since the PCM knows the amount of air and fuel entering the engine and from the oxygen sensors the amount of oxygen remaining after combustion it can determine if the combustion process was rich or lean This is a direct feedback system and enables the PCM to Close the Loop Because the feedback from the oxygen sensors can only be applied after the fact it causes the PCM to chase its tail to achieve the correct combustion This chase can be observed clearly in the oxygen sensors output which under everyday driving conditions looks like a wave The combustion process is constantly oscillating between rich and lean As long as this process continues to change from rich to lean in a timely manner the PCM knows that the combustion is within acceptable limits If the oxygen sensor voltage stays high or low for too long then the PCM adjusts the amount of fuel delivered by the injectors This adjustment is called the Short Term Fuel Trim STFT correction Long Term Fuel Trim The main function of the PCM is to store and
