REplaced my front o2, then i got the code for it again, reset the ecu went away. Replaced my rear o2, got the code again, reset it and haven't driven since, anyone know why that might happen?

 

O2 sensor fuse.

 

hmm didnt know there was one, but i think this code may just go away now, just like the first one did, but i guess i'll check fuses.

 

So you have replaced all 3 o2s?....

 

Just asking... what was the cost of replacing the 02 sensors?

 

~67 a piece from oxygensensors.com i replaced the rear and the front, the "middle" one didnt get replaced yet since i didnt throw a code on it yet. the fuse is okay... so idk whats up, unless its my ecu

 

when I got a code for the front, I just replaced all three and every thing worked out fine... Infact even though I was only getting a code for 1 of 3, I tested all 3 using my multimeter and all of them were not functioning correctly...

 

The rear one is only for emission purposes so I would only replace the front two. Thats what I did.

 

well i've only got one left to replace and we'll see if i do it now or not, i guess with 138,500 miles its about time

 

+1^^^^^^^^^^

 

i got the code and replaced all of my o2 sensors, but still got the code afterwards. checked the fuse, and it was blown. replaced it, and im good. I dunno why you'd still be getting the code. Maybe the ecu is still learning the o2 isnt bad anymore

 

well i do have a technosquare ecu so i think thats the reason
