What does it mean when your ECU says p0172?
P0172 indicates that there is too much gasoline being detected in the exhaust gases exiting the combustion chamber. The ECU uses a number of instruments, such as the mass air flow sensor (MAF), oxygen sensors, and manifold absolute pressure (MAP) to monitor the air-fuel ratio of the engine.
What causes the O2 sensor to read p0172?
It is important to complete the entire diagnostic process when diagnosing P0172. Many people will replace the air-fuel sensor or O2 sensor as soon as they get a bad reading, but the root cause is often a dirty or faulty Mass Air Flow (MAF) Sensor or vacuum leak, thus causing the O2 or A/F sensor to read differently to compensate.
How to check p0172 with other bank 1 DTCs?
P0172 with other Bank 1 DTCs – If you note only P0172, maybe concurrent Bank 1 DTCs, such as a cylinder misfire, focus your attention on Bank 1. Fuel Pressure Drop – With the engine running, record fuel pressure, then shut the engine off. Fuel pressure may drop slightly, but should remain stable for at least 10 or 15 minutes.
