device in the emission control system that measures the amount
of oxygen in the exhaust pipe and then sends the information to
the electronic control module. The information provided by the
oxygen sensor is then used to determine the amount of oxygen
needed to perform efficient combustion. Less oxygen will result
to fuel left over after the combustion while too much oxygen
supply will cause the fuel-oxygen mixture to produce greater
amounts of nitrogen-oxide pollutants. Excess air is supplied in
the mixture than needed may even cause damage to the engine.
Defective oxygen sensor will provide inaccurate oxygen level
reading and will result to decreased engine performance and poor
fuel efficiency. Auto Parts Network carries all the parts you
need in maintaining the efficiency of your vehicle.
