  1. As i have read all the posts i just want to clarify some things that i think people will have some confusion ,as in my experience in diagnostics i have come across this proble a lot of times , but for the diy mechanic is somewhat confusing, as to cleaning the a/f meter, In new models the airflow meter has 2 main group of sensors incorporated in a single unit , being one the IAT and the other the AIR FLOW METER , the IAT sits on the outside and looks like a big DROP of syrup , cleaning this will make no diference in relation to the code , now if you look closely at the unit ,look deeply inside and you will see 2 little grey (car models will differ in color) zener diode "look alike" sensors These are the actual A/F meter components ,These are the ones to clean if you want to get rid of these problem,
