my check engine light came on and found code P0722 and P0133. no problem to change o2 sensor -probably should be changed . read lot of info about reprogramming and trying to decide.. if i just change the part... will the code still show up? Or should i get the reprogramming before replacing parts?? Also.. if i do not change parts.. thinking i only need reprogramming.... will this do any damage?? If i do change the parts.. will it clear the code?? my car is running fine. will it affect my car inspection?? what advise/info can you share?? has anyone had this problem??thanks
Po722 is a malfunction from the VSS, po133 is an oxygen sensor bank 1 sensor 1Change the ox sensor,and the VSS, and remove the negative battery cable from the battery for 10 minutes, that should clear the codes. You should not need a computer reflash. A reflash is only used as a last resort, To expensive to just have a reflash without having everything checked out first.
