Re: What does code 0171 mean?
the majority of the time on this model car the p0171 code is caused by a dirty mass airflow meter but you can see the dirt if you remove it and look up inside of it there are two tiny wires that sense air flow if they get dirty it can cause this code but if you are not shure how to cheak this i would just take it to a shop or a dealer because it can still be a vaccume leak or clogged injectors or 02 sensor problems but most common is the mass air flow sensor
