Bosch Wideband O2 Sensor Wiring Diagram

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.

Bosch wideband o2 sensor wiring diagram.

Premium wideband a f o2 oxygen sensors. To date bosch has produced 1 billion oxygen sensors. I am wiring a bosch lsu 4 2 wideband to an aem infinity 508. 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.

From there production grew steadily and the oxygen sensor became an essential tool for fuel efficiency and the reduction of co2 emissions. 1 identify the two heater wires first 2 wires that are the same color and match. 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. Bosch 5 wire wideband o2 sensor wiring diagram wiring diagram is a simplified standard pictorial representation of an electrical circuit.

The bosch wideband has 5 wires on a 6 plug connector. Bosch oxygen sensor installation guide page 5 of 7 use the wire color reference table to determine the proper wire connection. As far as possible install the sensor vertically wire upwards. 5 wire o2 sensor diagram e30 wiring vs 1431 wideband 4 lsu connectors and library xb 1235 innovate as well bosch 2 wx 5621 for oxygen free broadband raspberry pi a lambda controller display problems audiforums com 5 wire o2 sensor diagram e30 wiring vs 1431 wideband 5 wire 4 o2 diagram lsu connectors and wiring 5 wire read more.

In a rich mixture the oxygen ions will combine on the pump cell s catalytic. The narrowband sensor described above detects the voltage v s produced by the nernst cell. It shows the components of the circuit as simplified shapes and the gift and signal friends amid the devices. Can anyone explain whats happening inside the plug that requires this extra wire.

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 s been more than 40 years since bosch invented the oxygen sensor and began series production in 1976. The exhaust gas passage opposite the sensor must be free of leaks in order to avoid the effects of leak air. But there are 6 wires that go to the ecu side of the plug and aem says it has to be wired that way.

That same year the volvo 240 260 series became the first passenger car equipped with the new bosch sensor.
