Depending on what the O2 sensor reports, the PCM will adjust the amount of fuel it's injecting into the engine. Here are some more specifics: 1. If the PCM in your Ford vehicle injects too much fuel, the oxygen sensor produces a voltage above 0.500 Volts.This voltage can go as high as 0.900 to 1.0 Volt. Too much fuel means that the air fuel mixture is Rich and once the PCM sees this report from the O2 sensor, it starts to inject less. 2.oo little fuel means that the air/fuel mixture is too Lean and the PCM starts to inject more. 3. This process (of adjusting the amount of fuel being injected) by the PCM, goes on the entire time the engine is running (and if the O2 sensor is working correctly).
