Diagnostic trouble code P0171 means System Too Lean (bank 1). That means the car computer noticed the engine is running lean. A lean system means the air-fuel ratio entering the combustion chamber is not what the engine wants. It means there is too much air or too little gas to balance the specified mixture ratio.
One of the most common causes of the P0171 engine code is a fuel system leak. When your fuel system leaks, more air and less fuel will enter the engine's cylinders. This results in your engine running lean because it can't get the necessary amount of fuel. Another problem with the fuel system is clogged fuel injectors.=====Claim your FREE engine code eraser 👉 https://free.nonda.co 👈===== How to Fix P0171 =====Engine Code P0171 Saving Repair...Greetings viewers!

On a good WOT pull the pressure climbed to 1800 - 2125 psi range. When coasting to a stop ( foot off the gas ) the fuel rail pressure briefly dropped to 280-350 psi range then returned to 425-440 range. On a cold start the pressure was 1800-2050 for the first 30 seconds or so.. Hope these number can help you out. J.The P0171 code means that more air than gasoline is detected in the exhaust gases exiting the combustion chamber. If the P0171 is set in along with the P0174 code, it is highly likely that the problem is caused by an intake leak. If there are no intake leaks, the next step is to replace the air filter and clean the Mass Air Flow (MAF) Sensor.
