The exact error is P0155: O2 Sensor Heater Circuit (Bank 2, Sensor 1)
So I talked to a mechanic and he said that many times its an electrical issue and not actually a faulty sensor. So I checked the fuse box and there were two fuses marked as "O2 Heater" (32 - ENG BAR 4, 33 - ENG BAR 3). 33 has a fuse in it that is fine. 32 has no fuse. I have to assume there has never been a fuse in 32. Should there be one?
The mechanic quoted me $45 for diagnostic and $150 for parts and labor if he has to replace the sensor. Does this seem fair? Anything else I should check for before I take it in?
Thanks much!
