This page describes various sensor topics, focusing on the Bosch LSU range of true wideband sensors.
These are 5-wire pump cell sensors.
The sensors requires a bung with an 18 mm diameter hole with 1.5 threads/mm pitch (M18x1.5)
and this is one of the standard lambda sensor & spark-plug base sizes.
Note that a wideband sensor should NOT normally be placed in an existing bung
designed for a narrowband sensor because this position will usually be too hot.
The pump cell is inside the white ceramic rectangle shown in the image at left.
It's just over 4 mm across so it's quite small.
The image below right is a cross section drawing of a complete LSU sensor with
the red circle indicating where the pump cell is located.
Here is more technical information on the Bosch 0 258 006 066 LSU-4.0 sensor.
You will find some web documents (including some from Bosch) describing the 6066 as an LSU-4.2 sensor.
It's NOT electrically equivalent to the newer 4.2 sensors but can be used with some controllers that allow free-air calibration
The latest LSU-4.9 sensors are even better than the LSU-4.0/4.2 sensors but they require different hardware/firmware.
A controller designed only for an LSU-4.2 will not work at all with an LSU-4.9 sensor.
Tech Edge sells controllers that can be set up to work with both.
Tech Edge has used the following LSU sensors with the WBo2 unit. The differences are in the connector and the calibration values required.

A number of vehicle manufacturers currently use a Bosch LSU 4 wideband sensor on their production vehicles. Feel free to contact us and add to the following list. Where there are multiple part number, like 057/058 they refer to the same sensor with longer or shorter leads. A sensor in this list doesn't imply the Tech Edge WBo2 unit supports it. See also www.forparts.com for another list of vehicles using Bosch wideband sensors.
