Instead of setting up a timer to feed a pulse train to the nernst cell we just apply a single pulse to to port b2 and measure the dc voltage a short time. But there are 6 wires that go to the ecu side of the plug and aem says it has to be wired that way.

Bosch lsu 4 2 wiring diagram. Lambda 065 to u wide band u exhaust gas temperature range max for short time 1030c u max. Lambda bosch lsu 42 wiring sq6 series. Bosch number is 0 258 006 066. If you want to attempt then the likely set up for the wiring is as follows. The bosch wideband has 5 wires on a 6 plug connector. 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.
Pin 38 lambda pump current is wbo ip pin 68 lambda is wbo vs wbo vsip is not known to us. In a rich mixture the oxygen ions will combine on the pump cells catalytic. The narrowband sensor described above detects the voltage v s produced by the nernst cell. Controllers must be recalibrated if changing between lsu 40 and 42 sensors. I am wiring a bosch lsu 42 wideband to an aem infinity 508. O 2 4e 2 o 2.
Unlike many other ecu systems emu has built in wideband lambda input bosch lsu 42 sensors wire directly map control connector 4 bar map sensor on board 2 egt probe inputs and an input for directly connecting a flex fuel ethanol content sensor. You will also need to supply 12v from the ecu supplies a ground which you havent specified a pin for and supply the heater from one. Section 27 bosch lsu 42 data sheet the target resistance is 80 ohms. 6066 is an lsu 40 sensor. The 49 sensor is very different to the 4042 and also requires a bias current. A resistor and capacitor are used to filter this ac signal and a dc value can be read by one of the adc channels.
Bosch lsu 42 sensor with special wego connector part 115002 18 x 15mm hex socket plug for o2 bung mild steel part 115003 18 x 15mm weld bung mild steel part 115004 12 foot extention cable from wego to o2 sensor part 115005 cd ignition tach adapter for use with nc 1 sl 1 all wego systems. Hexagon temperature 570c this sensor is designed to measure the proportion of oxygen in exhaust gases of automotive gasoline en gines. Bosch number is 0 258 017 025. 17025 is an lsu 49 sensor. All of this provides greater flexibility reduces costs and negates the requirement for.
