To make the subject of “Lambda Sensors” more intelligible and to simplify the process of inspecting them in the everyday work of an automotive garage, we show you here the construction and function of a lambda sensor and explain a number of ways of testing them. This technical video gives you practical information and demonstrates how to professionally exchange or replace the lambda sensor. It also cites some typical defects in lambda sensors.
Usually, the function of the oxygen sensor is tested during the routine exhaust emissions test. Since it is subject to a certain amount of wear, however, it should be checked for perfect function regularly (approx. every 18.750 miles ) – within the context of a regular service, for example.
The following technical information and practical tips were created by HELLA to support professional automotive garages in their daily work. The information presented here on this website should only be used by trained automotive technicians taking the respective safety regulations and country-specific legislation and practice into account.
