Hello and welcome to JustAnswer!

P0171 and 172 are both fuel system lean codes. These set when the engine controller is seeing a lean condition and adding fuel to the extent of it's capability and cannot bring it back to center. Low fuel pressure is a common cause or a lean code setting on both sides.

What year and model is the vehicle and what engine do you have?
