Testing L1H1 sensors
 

So I have 1 L1H1 O2 sensor in my VX, and 2 more on my workbench. Both used, but in cosmetically good shape (for what it's worth). What can I do to test the three sensors and determine which may be in the best shape?

I could have sworn I saw some O2 flowcharts somewhere...

No can't test on bench. There are some resistance test to do but that doesn't mean they are 100% good sell me one. I need one and you'll still have a spare. Thanks. Pm me.

I need one too if you want to make some extra money:)
