(O2) Oxygen Sensors – Function, Failure Symptoms, Testing Procedures

So, Cars with (O2) sensors have a minimum; of one sensor in front of the catalytic converter. Also, One in each of the car’s exhaust manifolds. But, The actual number of oxygen sensors for a car depends on the year; make, model and engine. However, most of the later model vehicles have four oxygen sensors.

When a gasoline-powered engine burns gasoline there is oxygen present. So, Oxygen in an engine; is the result of a number of factors. Including the air temperature; altitude, engine temperature; load on the engine; and barometric pressure. The ideal ratio for oxygen and gasoline is 14.7:1; which slightly varies depending on different types of gas. In the instance that there is less oxygen present; fuel will remain after combustion. Consequently, Referred to as a rich mixture.

Both the rich and lean mixtures are bad for your car; as well as for the environment. A rich mixture results; in a fuel that is not burned. So, A lean mixture generates nitrogen-oxide pollutants. As a result, Leading to decreased vehicle performance and engine damage.

Typically, an (O2) sensor creates a voltage; due to a chemical reaction resulting from an off-balanced gasoline to oxygen ratio. Consequently, Most car engines can determine; how much fuel to expel into the engine. As a result, Of the voltage of the (O2) sensor. If your oxygen sensor fails to function properly; your engine management computer; cannot determine the air to fuel ratio. As a result, The engine is forced to guess how much gasoline to use. Therefore, Resulting in a polluted engine; and a poorly functioning vehicle.
