took the waveforms from a skoda octavia with a bad intake leak. i closed of the leak to check for reaction. the lamda sensors look to be reacting correctly but im concerned about the voltage values? same with cam and crank. i was expecting to see the cam switch from 0v to 5v but im seeing battery voltage. any input is great, thanks.Hi,

I am not surprised at all with cam output voltage, try to think outside the box
If the voltage battery feed source is 5 volts you get 5, so if it gets 12 volts then why not to show 12 volts output signal.
By the way Citroen Xsara Picasso 2003 2.0 Liters Diesel engine displays a square 12 volts output signal for the cam sensor.
Cheers and happy scoping
