Hi. I suspected, that my Toyota Echo 2000 runs lean. I tested oxygen sensor and was getting readings 0.2V which is lean mixture. But I was very surprised, because I didn't get "check engine" light when I was doing that. I thought it would come on emmideately sinse I disconnected sensor??? It was disconnected for 10 min. I even ran for
5 min with it disconnected. So, now I know that sensor is ok, byt OBD2 doesn't receive the signal and doesn't corect mixture. What is the problem??? Do I need to go to diller and check the computer??? Any help, please... Thanks.- posted
