code (P0174) system too Lean (B2)

p= trouble code system
0= type of code
1= affected subsystem
74= specific code (exact problem)
the reason why your light came on is because it passes 1.5times the emission levels for the car as it was originally certified by the EPA.

my guess would be the 02 senor just bring it to the dealer and have them run a diagnos .. they can track down the (freeze frame Data) is a snap shot of the critical engine operating condition that is stored at the same time a (DTC) is set. From there they can found the problem an fix it.

the reason why your light came on at about 20 miles, is because your car have come to a (Drive cycle) which mean the engine start, operate until it enters closed loops, (closed loop) is when Air to fuel ratio keep it at a stoichiometric balance based on the signal to the (ECM) from 02 sensor/ or other senor and then shut down... is really confusing when it comes to codes just bring it to a dealer...
