What do p0171 code mean

Fuel system - Bank 1 lean.

This is usually due to a dirty MAF sensor heated wires. Remove MAF Sensor and spray the tiny heated wires with carb cleaner or MAF sesnor cleaner. ALso, look for air leaks in the air intake system that is allowing unmtered air to bypass the MAF sensor.
Your oxygen sensor is eprting that not enough fuel is going through the injectors. Look for splits in the convolutes of the big air intake hose. Also, the PCV valve could be bad
My guses is there is an air leak.

Service engine soon light on - codes P0171, P0174, P1131 and P1151 on a 2002 4.6L V8 Does this combination of codes focus on a particular emission component?

Hi, 1151 is an 02 sensor code, 1131 is also 02 sensor code,
0174 lean condition bank 2, and 0171 is lean bank 1. Either this is in need of a whosale of repairs or you have computer issues, From looking at the codes i would first do a complete tune up, Including wires, And inspect for a vacume leak before replacing any 02 sensors..
Take care

it's a oxy sensor code for lean fuel misture. try cleaning sensor first. change fuel filter and add a can of SEAFOAM to tank of PREMIUM gas. *** SEAFOAM 3-5000 miles, andd it should take care of this ethanol gas problem. I hate ethanol gas,

Trouble code P0171, P2195 Ford Focus

Even though your O2 sensor is showing good by your scan, it could be lazy in giving readings. It has less than a 10 second window to give the reading especially if it is a heated O2 sensor. Try a Bosch unit.
