Wideband Oxygen sensors testing and operation was created by Babalola
Hi 
I have a 2012 Mercedes C class with a 264 petrol engine. It has a P0420 fault code, but the engine runs fine. Can you point me to any material you have for testing the wideband sensors and cats specifically with wideband sensors? I have found a video on YouTube by schrodingers box about wideband sensor operation and testing, which was very helpful. I wondered if anything similar is available by scanner danner and leading on from the operation and testing of the wideband sensor how to test the cat. The video I did find on the P0420 fault code cat testing/A/F  sensors was also very helpful, are the basics the same for a wideband cat vehicle ?

Many thanks in advance

Victor
