The P172A fault code refers to a problem with the Auxiliary Transmission Fluid Pump. This code is set by the Engine Control Module (ECM) when the pump is not operating according to the factory specifications. The specific issue indicated by this code is the reverse rotation of the Auxiliary Transmission Fluid Pump.

When this fault code is triggered, it means that the ECM has detected that the pump is not functioning correctly. The pump is responsible for maintaining the proper flow of transmission fluid, which is crucial for the smooth operation of the transmission system. If the pump is rotating in the wrong direction, it can lead to a disruption in the fluid flow and cause issues with the transmission’s performance.

If you encounter the P172A fault code, it is important to have the Auxiliary Transmission Fluid Pump inspected and repaired as soon as possible. Ignoring this issue can lead to further damage to the transmission system and potentially result in costly repairs. It is recommended to consult a qualified mechanic or technician who can diagnose the exact cause of the problem and provide the necessary repairs to resolve the fault code.
