We’re pleased to announce the addition of a new Bosch LSU 4.2 broadband oxygen sensor switching test to our PicoScope 7 Automotive software.
Broadband (or wideband) oxygen sensors like the Bosch LSU 4.2 are now widely used across a huge range of modern petrol and diesel vehicles. Ranging from everyday passenger cars to light commercial vehicles, motorcycles and performance vehicles. As emissions regulations have tightened and engine management strategies have become more advanced, broadband oxygen sensors have become a critical part of achieving precise fuel control and cleaner combustion.
For technicians, the growing number of vehicles using these sensors means accurate diagnosis is more important than ever. That’s exactly where this new Guided Test helps.
Supporting confident diagnosis
Whether you’re new to automotive diagnostics or already experienced with oscilloscope testing, this Guided Test provides the structure and confidence you need to perform professional diagnostics. With a dedicated test preset, PicoScope automatically configures the relevant channels for you. From there, the Guided Test gives step-by-step instructions on:
- Connecting to the correct parts of the circuit
- Capturing reliable data under realistic engine operating conditions
- Interpreting typical signal behaviour to confirm correct or faulty operation
The test also explains how the oxygen sensor’s signal responds under various load conditions, including idle, acceleration and deceleration. This allows you to compare what is expected vs what happens in real time.
Business benefits you can rely on
By removing the guesswork from broadband oxygen sensor diagnostics, this Guided Test helps you to increase your first-time fix rates and improve customer trust and satisfaction. You will gain a more accurate, efficient diagnosis, meaning fewer RTWs, reduced parts wastage and improved workshop reputation.
The new test is already available within the PicoScope 7 Automotive Guided Tests. Download the software now from https://www.picoauto.com/downloads
