o2 sensor replacement
Hey I'm need of knowledge on how my car should react after installing an o2 sensor first off it idles real smooth after hooking it up and putting it in. The code that I pulled (P0037) is now gone. But here is my problem I've been scanning my ECU over the past 24 hours since i put it in. On my my scanner it also has IM monitor status which will tell me whether i'll pass inspection at first four icons flashed where the IM status is (EV=Evaporative System Monitor,2A Secondary Air System Monitor,O= Oxygen Sensor Monitor, and OH= Oxygen Sensor Heater Monitor) after a while of driving O and OH went away by the end of the night EV and 2A remained then today I checked during my lunch break at work and only the icon for O remained and then I shut my car down and scanned again and all four icons were flashing again. I just got home and scanned it a few minutes ago and now it's 2A and EV flashing. What's going on here? Is there anybody there that might possibly know what's going on with that? It is a CanOBD2 Code reader model # 3100a. I have absolutely no clue what that's all about with the flashing icons for those things. Any help at all is graetly appreciated. Thank you very much.
