| Re: confused with codes
These codes are not related, the maf sensor would have to be done first as you go by the lower code numbers first, this is not a hard job at all to do, first check the wiring to the sensor and make sure its not abraided or cut, then check the intake airbox for a clean filter, a dirty filter may cause the problem on Deaccelartion. As for the P0443, this is a evap code and it means that something is not working right in the emissions department, but changing the ECM, I don't think you are anywhere near that. In fact most of the diagnostic trees for all codes usually end with 'Replace ECM and Recalibrate' so try those first, I would suggest that you take it to a shop that knows what they are doing in regards to this problem, a dealer for instance, after you get your sticker, buy a Factory service Manual and do some of these yourself, it will amaze you on how much you can then do and it will save you all kinds of money. Good luck |
