Hey guys I when i started the 8 up this morning my check engine light came on, so i read the code w/ the AP and its P0037, which from doing a little research looks like the rear O2 sensor.

Any idea on how much this cost to fix or if I can do it myself? any help is greatly appreciated.

 

You could do it yourself. I banged my exhaust hard the other day and *** packed my O2 sensor into my tranny but the light isnt static. If the O2 is dead than you can jack up the passenger side of your car. Crawl under with I think a 20mm or 21mm wrench. Some WD40 and make sure your on that sensor straight. I do not know how much exactly it costs for a new O2. Someone told me it was 100-300 bucks. I could be wrong. I need one too so maybe you can let me know.

 

might be your cat going out too.. just buy a midpipe and mask the code with your ap.

 

This is true. I am going to check with University Mazda on a O2 sensor, but if it does cost more than a $100+ then the midpipe might be the better option. Any known issue with driving the car daily until i fix this? I dont want to make matters worse.

 

not that i know of..
