so now the government wants you to have all your dignostics codes cleared for next year inspection. im so sick of the government getting in every aspect of my life. i have a oxygen sensor code that i have to have replaced by next year,$500dollars.can someone tell me what these codes are and what i need to have fixed: P0056ho2s heater control circuit bank 2 sensor 2......P1170 code.....P0160 O2 circuit sensor bank 2....P0159 O2 sensor circuit bank 2 sensor code....are the P0159 and P0160 the same oxygen code....




and are there any cheaper sensors than the dealer>>>> and are they hard to replace?and where are they located?
Ok, first off if you have less then 110k on this truck then you probably had a bad cat that is causing the code cause its got a leak. Good news is if its under 110k you can get a new cat from the dealer. When they replace the cat if the oxygen sensor is frozen in then they will replace those frozen in. Good news though sometimes when all the sensors are frozen in they replace the cats under warrantee and you pay for the sensors. That way you don't come back next week with the same code and something else they have to fix. Be nice to the dealer and you might be surprised they might help you out on quite a bit.
