Fuel System Too Rich. P0172 is thrown when the oxygen sensors detect that the air-fuel mixture is too rich. A rich fuel mixture contains too much fuel in relation to air. The A/F ratio for ideal combustion is 14.7 parts air to 1 part fuel (14.7:1). With that in mind, either too much fuel or not enough air can cause a vehicle to run rich.The fuel rail pressure sensor keeps the powertrain control module (PCM) aware of the pressure levels in the fuel rail, so that the computer knows how much fuel the engine needs.
