If spark plugs are misfiring (fuel isn’t ignited in those cylinders) so there will be excess oxygen (because it wasn’t consumed by the burning fuel). The O2 sensor ahead of the catalytic converter will detect this and the ECM will set a code.

What happens if oxygen sensor is not replaced?

Cars with O2 sensors have a minimum of one sensor in front of the catalytic converter, as well as one in each of the car’s exhaust manifold. 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.

How much does it cost to replace an oxygen sensor?

What causes an oxygen sensor to fail?

O2 sensor failures can be caused by various contaminants that enter the exhaust. These include silicates from internal engine coolant leaks (due to a leaky head gasket or a crack in a cylinder wall or combustion chamber) and phosphorus from excessive oil consumption (due to worn rings or valve guides).
