A P0172 code indicates that the fuel system is excessively rich or inadequate air in the engine’s air-fuel mixture. The code appears when there is too much fuel in the exhaust gas flowing from the combustion chamber. The code could imply the following. A vacuum leakage near the engine. The fuel system is operating weak.Nov 21, 2023 · OBD II fault code P0171 is a generic code that is most commonly defined as “System Too Lean- Bank 1”, and is set on gasoline engines when the PCM (Powertrain Control Module) detects that the air/fuel mixture is too lean. In this context, “lean” refers to a condition where there is too much air relative to fuel in the mixture. To keep the engine operating properly, the powertrain control module (PCM) attempts to compensate for the lean state by injecting more gasoline into the mixture in an attempt to maintain the proper 14.7:1 ratio. When these modifications become too large, the Chevrolet P0171 code is activated. What causes P0171 in a Toyota?

The automaker has reached a deal that will have LG pay nearly all...The oxygen sensors are always monitoring how much fuel and air is in the mixture. If there is a vacuum leak, it can cause excess air supply to the engine bay. Then, the O2 sensors will detect a rise in air. Also, broken oxygen sensors can trigger the P0171 code. They can do a false readout, which will trigger a code.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.
