What does trouble code p0172 mean on Mazda 3?
A common trouble code with the Mazda 3 is P0172. This code number references a number that is given to you when you plug your car into a OBDII scanner. It’s not the most complicated OBDII trouble code to diagnose. It is also one of the most common. It means that the motor is running with a rich condition.
What is the meaning of the code p0172?
Code P0172 Definition Bank 1 has more fuel then it should or not enough air. What Does P0172 Mean? Combustion engines run most efficiently when they maintain an air-fuel mixture ratio of 14.7 parts air to 1 part fuel.
What causes a car to run out of p0172?
What Is The Cause Of P0172? 1 Dirty or faulty Mass Air Flow (MAF) sensor 2 Faulty oxygen sensor 3 Faulty air-fuel ratio Sensor 4 Leaky fuel injectors allowing too much fuel into the combustion cylinders 5 Worn spark plugs 6 Stuck fuel pressure regulator 7 Faulty coolant temperature sensor 8 Faulty coolant thermostat
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.

What to do if check engine light code p0172 persists?
If check engine light code P0172 persists after you have inspected the air intake system and cleaned the Mass Air Flow (MAF) Sensor, perform a fuel pressure test. If any components in the fuel system are failing, replace them as necessary.
What causes air flow code p0172 and p0175?
The fuel mixture grows rich and eventually, the code sets. An “over reporting” Mass Air Flow Sensor can be a common cause of a code P0172 and P0175. Essentially, this means that the Air Flow Sensor is telling the computer that much more air is entering the engine than actually is.

A common trouble code with the Mazda 3 is P0172. This code number references a number that is given to you when you plug your car into a OBDII scanner. It’s not the most complicated OBDII trouble code to diagnose.
What does p0172 mean on a Chevy Silverado?
It’s not the most complicated OBDII trouble code to diagnose. It is also one of the most common. It means that the motor is running with a rich condition. P0172 is thrown when the oxygen sensors detect that the air fuel mixture is too rich.
What happens if the p0172 code is too rich?
If the the air-fuel ratio is rich enough, a black smog will come out of the exhaust, which is harmful to the environment. What repairs can fix the P0172 code? It is highly recommended to check the condition of the spark plugs and the operation of the coolant temperature sensor. Need help with a P0172 code?
