Bosch lsu 4.2 replacement o2 sensor. This is inspired by the bosch 4.9 wideband 02 sensors. Oxygen sensor wiring colour code guide number of wires on sensor man sensor brand 1 2 3 4 function gm delphi i violet this chart can not be copied, reproduced or published without the written authorization of hiflo pty ltd. I did not include the pig tail on the end of the sensor, as there are both a general automotive and a motorsports harness that is available with this same sensor.

Mine are new bosch from pelican parts. It's risky using a voltmeter or test light to find the hot wire(s). Wideband 2 sensors typically have 5 wires while most a/f sensors have 4 wires. You cut the plug off your old one and wire it to the new sensor.

He asked for a wiring diagram, checked my bentley, not in there. When working with block diagrams, user's will notice a drivven function palette added to the standard labview palette, specific for the rt or. The second test involves causing an artificial rich condition (more hydrocarbons than expected). I bought a denso 4 wire and the wires were all the same colors as on the oem, so i soldered the new one on to the old harness and am now getting a.

I know that one of these is the actual signal to the ecu i beleive bosch and ngk both ahve some o2 sensor wiring diagrams oin thier websites as they both offer some generic replacement o2 sensors. On the car he has 5 wires, (white, blue, yellow, gray, black) on the bosch sensor there is 4 wires (white, white, black gray). The bosch wideband has 5 wires on a 6 plug connector. The latest generation widebands are compatible with both the bosch lsu 4.2 and 4.9.

The main benefit of the lsu 4.9 is the robust design combined with the high bosch production quality standard. This sensor is designed to measure the proportion of oxygen in exhaust gases of automotive engines (gasoline or diesel). One blue, one white, and two black. The two whites are going to be the heater.

Not even a year old. Please note that the sensor connector is different for each sensor. On pg 3, it shows the harness from the o2 sensor goes directly to the x11 diagnostic port (the small one on the side of the i totally get that an o2 sensor should not put out more than 0.9v. Bosch lambda sensor universal (lsu) 4.2 wideband oxygen sensor.

• premium universal oxygen sensors with oe smartlink are quick and easy to install. Another way to check the output of a wideband o2 sensor or a/f sensor is to connect a digital voltmeter or graphing multimeter in series with the sensor's voltage reference line (refer to a wiring diagram for the proper. I am wiring a bosch lsu 4.2 wideband to an aem infinity 508. Note that the external wiring diagram in this sensors and wiring section is entirely separate from, though similar to, the relay board.
