The exhaust gas passage opposite the sensor must be free of leaks in order to avoid the effects of leak air. It took 32 years from 1976 to 2008 to reach the production record of 500 million pieces but only eight years from 2008 to 2016 to.

It is possible to force a current through the molten electrolyte and to drive the chemical reaction such that oxygen is pumped in the form of o 2 ions from one side of the cell to the other. But there are 6 wires that go to the ecu side of the plug and aem says it has to be wired that way. Protect the sensor against condensation water. As far as possible install the sensor vertically wire upwards.

The sensor is not to be fitted near to the exhaust pipe outlet so that the influence of the outside air can be ruled out. Wideband air fuel sensors perform the same function as a regular o2 sensor but they precisely measure the amount oxygen in the exhaust rather than just switching between rich too much fuel not enough oxygen and lean too much oxygen not enough fuel.
