Yes, it's the passenger side rear.. And I thought about getting some MIL's since they are only between 60-70 after I already picked up a new o2 sensor, which was itself $73, and tried to remove my old one, which didn't work..
Yeah, see I just bought a new one and decided to just change it out... And when that didn't work, let me tell you I tried.. Heated up the exhaust, sprayed some PB blaster.. Wouldn't budge. So I didn't want to take it in even if it was going to be like $30 to fix it when I can just get some MIL's and it'll be cheaper that way.
MILs will NOT shut the CEL off if the actual o2 sensor is bad.
They only work on a functioning o2 sensor.
You need to heat it up and remove it so it can be replaced.
