2002 GTS with 205K miles had P0171 CEL, engine too lean, wont pass smog test.
Mass Airflow Sensor looked dirty. Cleaned with carb cleaner, but did not help.
Swapped a MAS from another car, worked beautifully, cleared all codes, passed smog test.
OEM and Denso MAF retail about $220. Will buy a Chinese knock off in eBay for $20 to see how well it works and how long it lasts.

The $20 counterfeit MAF bought on eBay is not working.
The car runs rough, has no power for acceleration, and is doing P0171 SYSTEM TOO LEAN AGAIN.
Damn counterfeiters are making bad sensors with TOYOTA and DENSO part numbers on it.
I will forward the fake info to Toyota, Denso and Law Enforcement so they can deal with fakers...

The MAF sensor bought for $26 on eBay works fine in a Lexus that uses the same sensor.
It did not work in the Celica. The car had no starting acceleration. I got into the intersection when the car failed to move. I was nearly broadsided by incoming traffic. So What can I say?
Put the original MAF back and the Celica runs great again.
Put the $26 MAF sensor in the Lexus, the Lexus runs great. No problems, no check engine light...
Not sure what happened.

Carb cleaner fluid may have lubricating oil, which would screw up the MAF sensor.
MAF sensor should be spray cleaned only with CRC MAF cleaner or residue-free electrical contact cleaners.
