Ok so I have been trying to get rid of this p0135 code for a while now with no luck. First things first,
installed a brand new delphi 02 sensor upstream. Erased the code with the scanner. 3 days later the same code comes back up.
Bring the car back in and they run diagnostics to check what the problem could be, then they say that the sensor itself may be the issue with the sensor itself getting a reading of 8 ohms (suppose to be 5 ohms)?
Where else could I go from here? Another sensor is going to run like 150$
wtf?!
