Got my car scanned at autozone and got p0133. Said oxygen sensor. Cant find 0409 in sticky. Which sensor is this? What are my problems if I dont replace this? My car doesnt seem any different then it did before this code came up. Is anything effected with a bad o2 sensor?
Thanks,
Matt

 

bump... no1 knows?

 

I had this code, it's your left front o2 sensor, and it will affect your gas mileage and acceleration. unless your KS code is also triggered by a bad o2 sensor, then both can affect power and mpg.

 

Wierd my Light went back off... did the o2 sensor fix itself? ... lol

 

It seems like the O2 sensors have a tendancy to do that from what I have gathered on this site.

 

test it again, or go to a auto store and have them pull codes.
