The code P0172 indicates that the engine control module (ECM) has detected a rich air-fuel mixture in the engine, meaning there is too much fuel relative to the amount of air. This can be caused by issues such as a malfunctioning fuel injector, a clogged air filter, or a faulty mass air flow (MAF) sensor. Addressing this issue typically involves diagnosing the underlying cause and making necessary repairs to restore the proper air-fuel balance. Ignoring a P0172 code can lead to poor engine performance and increased emissions.

How do you fix code p0172 on a 97 ford f-150?
This is a code for "system too rich Bank 1". To me it sounds like the first step would be to block the evap flow to the engine and see if the po172 code stays cleared! If it does then I'd suspect a valve/solenoid in the evap system isn't staying sealed and causing the engine to run too rich which is also a cause for a po455 dtc! the 1451 dtc points to an issue with the cannister vent solenoid which could be causing all 3 codes.
What does the OBD2 Code PO172 rich on bank 1 and PO174 lean on bank2 suggest on my 1998 silveroda pickup?
If you have not changed the Oxygen sensors I would do that. The O2 sensors ( which are a maintance item) need to be replaced when you have incorrect fuel delivery problems. Mark I had the same codes on my 96 Silverado and it was my fuel pump. Usually your 02 sensors will have a {no activity},{no response} or {heater circuit malfunction} when they are bad.
How do you fix trouble code PO172?
Trouble code P0172 indicates that the engine control module has detected a rich fuel condition in bank 1. To fix this issue, start by checking the fuel system for leaks, inspecting the fuel injectors, and ensuring the fuel pressure is within specifications. Also, examine the mass airflow sensor (MAF) and the oxygen sensors for proper operation, as they can influence the air-fuel mixture. If needed, replace any faulty components and clear the trouble codes to see if the problem reoccurs.
