I have read a number of the posts regarding fault codes P0171 and P0174. The answer is clean and or replace the MAF unit. I have just cleaned mine and will take it for a run tomorrow. If I need to I will order a new MAF.
I have had this code a few times this summer and each time it has followed a fill with a particluar brand that is always cheaper by 10 -12 cents per litre and the stations are on the way to our fishing camp. It is the requisate premium gas and virtually every time the SES light is on within an hour or so after a fillup. On one trip it went out on its own after filling a very empty gas tank at another station. Is this just a coincidence??? Logically funky gas cannot affect the MAF but can it generate the identified codes?
This last time a new code P0734 was present - I take it this is related to the tranny but is a function of the other two codes or a separate indicator of a problem? If it is a separate issue what does the code indicate.
Any help would be appreciated!
