Bosch Wideband O2 Sensor Wiring Diagram

Can anyone explain whats happening inside the plug that requires this extra wire.

O 2 4e 2 o 2. Bosch oxygen sensor installation guide page 5 of 7 use the wire color reference table to determine the proper wire connection. Wideband o2 sensors and air fuel a f. 1 identify the two heater wires first 2 wires that are the same color and match.

I am wiring a bosch lsu 4 2 wideband to an aem infinity 508. As far as possible install the sensor vertically wire upwards. 5 wire o2 sensor diagram e30 wiring vs 1431 wideband 5 wire 4 o2 diagram lsu connectors and wiring 5 wire diagram wiring library. The narrowband sensor described above detects the voltage v s produced by the nernst cell.

But there are 6 wires that go to the ecu side of the plug and aem says it has to be wired that way. 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. 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. In a rich mixture the oxygen ions will combine on the pump cell s catalytic.

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.
