How do you calculate AFR?
When you use an AFR meter connected to an oxygen sensor that is placed in the exhaust stream of a combustion engine, the AFR meter will calculate the AFR for you through a complex set of equations specific to the sensor and the fuel type. The sensor heats up to a certain temperature and detects the amount of oxygen atoms in the air that passes it. As the oxygen levels and temperature of the sensor fluctuate, the AFR meter compensates for these changes and provides the user with an accurate lambda value that, for combustion engines, is multiplied by 14.7 to give the user an Air-Fuel Ratio value.
Which of 2 sensors top or side of airflow box on 2000 Toyota Avalon should be replaced for code p0171?
there is only one sensor on the airbox. its flat on top with 2 Phillips screws holding it in place and a 5 or 6 wire plug. the other thing has vacuum hoses to it and is a switching valve. ask for the mass airflow sensor when you go to buy the part. If you still cant identify it, call the dealer, ask for the price and part number for a MAF sensor, then match that number to the one on the sensor itself. the biggest problem I have with trying to fix a code P0171 with a MAF sensor is you could pay the $90.00 or whatever and have it not fix the problem. make sure its reading too low at idle before replacing it. check it on the data list of a scan tool, it should be between 2.5 and 3.5 gm/sec. if its lower, make sure the air snorkel between the airbox and throttle body is secure and not leaking. if that's ok replace the sensor. if its in range AFR bank 1 needs to be compared to bank 2. if its reading a higher voltage or isn't as lively at say 2500 rpm replace AFR bank 1. (its the first sensor in the exhaust by the firewall NOT THE ONE BY THE RADIATOR!

Where is the Mass Airflow sensor in a 2001 Outback H6?
There isn't one. It uses air intake temp, pressure and exhaust oxygen sensors to measure the AFR
