O2 voltage must varies with time, cannot stuck at 0.75v

Must use live data mode to check O2 sensor voltage, if it is stuck at 0.75 volt as some of the cheap sensors do, the feedback loop will produce errors, first in the pending code, late will show up as a reported error code!

所有跟帖： 

• 明白。萬用表的讀數其實一直在變，不過普通萬用表反應慢，一開始讀數低，過幾分鍾就會停在比較高的讀數。 -原上草2017- ♂ (0 bytes) () 09/22/2019 postreply 12:09:34

• 可以用示波器來看，不過嫌麻煩，不過有空可能會試試。 -原上草2017- ♂ (0 bytes) () 09/22/2019 postreply 12:10:52
