Postby S13AW » Tue Jan 08, 2013 9:07 pm

hello im new to using a pico got mine a few days ago amazed how much this thing can do, but ive come up to a 6 wire lambda sensor and was wondering how i would test it maybe ive missed it on the software or the notes :|

Not much you can do with a 6 wire. On some types there is a wire which shows inverse proportianality to lambda value, Frank Massey expalins that in one of his videos - can't remember which, or where I saw it sorry.
If you have a mind to and equipment to do it you could monitor pump current which is proportional to lambda value.
If its a bosch lsu type, there is a load of info RE: wire diagrams on the net.

You need a low current clamp something like 0 - 450mA to get good trace.

If you are able to measure current take care when looking at the rich / lean values.

There is only a very small change in current too.
