Low Fuel Pressure (possible plugged/dirty fuel filter!) Exhaust Leak between Engine and first Oxygen Sensor. Possible Solutions: A lot of Times, Cleaning the MAF Sensor and Finding/Fixing Vacuum Leaks fixes the Problem.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.2. Enter the VIN in the parts catalog and go to the fuel injector rail parts section. 3. After the injector part number has been identified on the body of the injector, in the description column. For example, part number 12668390 highlighted in the table. To the left is the part number that will need to be order.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.The powertrain control module (PCM) is responsible for monitoring the reading of the air temperature entering the intake. The PCM looks for the 5-volt reading from the IAT sensor. If it comes back higher than that, the P0113 trouble code gets set in the computer. The PCM uses this measurement to adjust the fuel-air ratio.
