  1. Last year, I was getting a "lean" code on my 2002 1MZ-FE Highlander. Cleaned the MAF but code came back. I found Toyota Technical Support Bulletin EG-5014, followed the procedure, and found the long term fuel trims for both banks were out of spec. The MAF data (g/sec) was also out of spec per the procedure, indicating a bad sensor. Replaced it and life is good.
