Bosch Lsu 4 2 Oxygen Sensor Plug

These sensors have a laser etched calibrated resistor in the sensor s connector body.

Bosch lsu 4 2 oxygen sensor plug.

This is borne out in the slight discrepancies between my results and what is typically expected. While the fix and testing wo. The 4 9 sensor is very different to the 4 0 4 2 and also requires a bias current. This sensor is designed to measure the proportion of oxygen in exhaust gases of automotive engines gas oline or diesel.

Bosch lsu wideband o2 sensor uego with bosch connector for oem replacement other wideband systems bosch 0 258 007 057 vw 021 906 262 b bosch usa 17014. But there are 6 wires that go to the ecu side of the plug and aem says it has to be wired that way.

For all other innovate widebands verify which sensor is being used. Aem s bosch 4 2lsu wideband uego o2 replacement sensor kit includes only the sensor with attached cable and male connector and is intended to replace an existing mounted wideband sensor used with aem wideband air fuel uego controllers. Its monotonic output signal in the range of lambda 0 65 to air makes the lsu 4 9 capable of be. This is the same sensor that ngk packed with the powerdex afx prior to 2010 and ballenger motorsports uses in the afr500 as the base sensor.

The wide band lambda sensor lsu 4 9 is a planar zro2 dual cell limiting current sensor with integrated heater. Controllers must be recalibrated if changing between lsu 4 0 and 4 2 sensors. The bosch wideband has 5 wires on a 6 plug connector. Can anyone explain whats happening inside the plug that requires this extra wire.

What makes lsu 4 9 superior to lsu 4 2 is not only because lsu 4 9 uses an electrical reference signal and lsu 4 2 uses the reference air but also because bosch significantly improved every aspect of the lsu sensor in the 4 9 version and made it a mass production level with superior reliability and quality. The latest generation widebands are compatible with both the bosch lsu 4 2 and 4 9 but the sensor connector is different on each one.
