Question about 2005 Ford Freestyle
P0171 is a lean code,,for bank number 1
p0174 same thing but for bank number 2
P016B - Closed Loop Air/Fuel Ratio Control at Limit - System Too Rich p0176 flex fuel sensor (ouch , they are expensive ) as far as the 2106 code, this is a messy one,, its some sort of internal Ford code that has to do with the throttle body , Ive read numerous forums on this code,, and It usually shows up with others that match ,, yours doesn't seem to coincide with that,, if your in a town with a autozone, they will check your codes for you and have the breakdown of them in each store

System Too Lean (Bank 2)
Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust.
Note: This DTC is very similar to P0171, and in fact your vehicle may show both codes at the same time.
