I guess this is one of the things I don't like about my diesel.

P1102 - MAF reading in range, but lower than expected.

With the ScanGuage I could reset the code, but it came right back. But, the van was running fine. So, I stopped at the next Ford dealer and they told me what the code meant.

Then I took the MAF out and noticed some 'whiskers' on the wires. I blew on the MAF and the whiskers went away. About 1/2 day late the code came back. Then I stopped at a NAPA store and got some 'Contact Cleaner' that was listed as safe for plastics. Sprayed the MAF, dried it and put it back. 1500 miles later, no more P1102.
