Lambda sensor readings

Hi does anybody know or how I can find out what the lambda sensor readings should be on a 2.5 v6?
Thanks

Its more the shape you are looking for I think - they are not wide band so just looking to see that its switching lean / rich at a sensible interval when closed loop.

Unless you mean you want to test them with a multi meter? In which case I have no idea how useful that is or what the impedance should be.

Essentially, look at the rich.lean cycle one up to temp.

The actual readings will cycle from quite low <100mA to quite high > 500mA at about 1Hz.
