looking for pointers on the testing of Lambda sensor
Max voltage was about 0.6 Volts, minimum was around 0.2V, this was measured between the output from sensor/input to ECU & earth. (ie the big thick GREEN wire & earth)
I found this link which 'sort' of helps. (I have 3 wires going to the unit, live, earth & signal)
http://www.picoauto.com/applications/lambda-sensor.html
Car was 'warm' oil temperature around 53, water unknown (sensor/display a bit iffy)
I did save the file as a dat file which I canna open, and I should have saved as a CSV which would have given me time base/levels etc.
suffice to say that there is about twelve seconds between the two vertical lines, so it is doing something, but maybe the wrong thing, last year's MoT it was TOO lean, Re-reading the pico-scope info it would appear that it should vary from 0.2 - 0.8V (0.2 is lean, 0.8 is rich) so if mine never gets above 0.6V then this explains last years MoT result.
How do I insert an image?? (I don't use photo bucket etc )
Looks like a new down-pipe?

Re: Testing Lambda output
lambda sensor readings are on the forum somewhere check john turbos posts
but the readings for a NA car are different. fiound out the hard way
