I recently changed my drivers side rear O2 sensor after getting multiple CELs indicating the heater was not working on the sensor (cant recall the specific code). I ended up having to have my mechanic replace the sensor as I could not get it to budge. They ended up having to put a new bung as the top of the old sendsor broke off (and still remains in the exhaust)
Admittedly I used a cheapo sensor as I have had decent luck in the past with other cars. Now I am getting the P1173 code which points at the new sensor as well as I have read PCV hoses. Should I replace the new sensor with a higher quality one such as a bosch (dealer wants $200 +) before tearing into the PCV hoses? Seems to be too much of a coincedence that it would not be the new sensor.
