WHAT A LEAN CODE MEANSA lean fuel condition may exist if the engine is sucking in too much air and/or the fuel system is not delivering enough fuel.

This code is not set on four cylinder engines (no bank 2). IF the vehicle is driven long enough, typically both codes will be set.ДЄ P0171 lean code for bank 1 is the cylinder bank on the RIGHT (passenger) side of the engine on Ford vehicles with a V6 or V8 engine and rear-wheel drive.ДЄ P0174 lean code for bank 2 is the cylinder bank on the LEFT (driver) side of the engine on Ford vehicles with a transverse-mounted V6 engine and front-wheel drive. When the Check Engine Light comes on, either one of these codes, or both, may be found when a code reader or scan tool is plugged into the vehicle diagnostic connector. These codes commonly occur on many Ford vehicles, and are set when the powertrain control module (PCM) sees the air/fuel mixture is running too lean (too much air, not enough fuel).
