Bosch wideband o2 sensor wiring diagram.

O 2 4e 2 o 2. 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. To date bosch has produced 1 billion oxygen sensors. 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.

The bosch wideband has 5 wires on a 6 plug connector. 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. The exhaust gas passage opposite the sensor must be free of leaks in order to avoid the effects of leak air.

From there production grew steadily and the oxygen sensor became an essential tool for fuel efficiency and the reduction of co2 emissions. It s been more than 40 years since bosch invented the oxygen sensor and began series production in 1976. In a rich mixture the oxygen ions will combine on the pump cell s catalytic. Protect the sensor against condensation water.

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. 1 identify the two heater wires first 2 wires that are the same color and match.
