Bosch LSU-4.x Main Page

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.

Alternate LSU Part Numbers

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.
