Trying out a new obd2 meter and wanted to show some live data meanings and how it can be helpful when troubleshooting. Web the readings from your wideband give you accurate and valuable insight into how your motor is running at any given time, and once you understand how a wideband gauge works it can also be used as a diagnostic aid in identifying mechanical problems and preventing engine damage. An a/f sensor signal increasing from 0 to positive tells the ecu that the combustion contains more oxygen and is therefore considered lean, and to resolve this more fuel has to be added.
