What causes P0171 and P0174 codes Ford f150?

COMMON CAUSE: A DIRTY MAF SENSOR One of the most common causes of Ford P0171 and P0174 lean codes is a dirty mass airflow (MAF) sensor. As a result, the engine runs lean and sets a P0171 and/or P0174 code (see Ford TSB 98-23-10 for details).

The most common causes of the P0174 code are the following: Vacuum leak due to damaged intake manifold gaskets or punctured vacuum and positive crankcase ventilation (PCV) hoses. Malfunctioning mass airflow (MAF) sensor. Clogged fuel filter.

Can a bad fuel filter cause a P0174 code?

A plugged Fuel Filter or poorly functioning Fuel Pump can set the P0174 code. The computer hears (accurately) from the Oxygen Sensor that the Fuel Mixture is too lean so the computer keeps increasing the amount of fuel being delivered into the combustion chambers.
