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 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 does ECM mean on Chevy p0172?
P0172 Chevrolet Meaning. The Engine Control Module (ECM) controls the air/fuel metering system in order to provide the best possible combination of driveability, fuel economy, and emission control. Fuel delivery is controlled differently during Open Loop and Closed Loop.
Why is my p0172 system too rich bank 1?
Check for an exhaust leak before the first oxygen sensor (this is unlikely to cause the problem, but it is possible) P0171 is showing on scanner but not a service light on , then after about 30 miles p0172 go’s active and turns service engine light on . Seems like it’s running fine ,but cannot get anyone to figure out the 172 code rich bank 1 .

What are the repairs that can fix the p0172 code?
What repairs can fix the P0172 code? 1 A repair of a vacuum leak 2 A replacement of a faulty fuel injector, fuel pump, or fuel regulator 3 Replacement of an excessively restricted air filter 4 Replacement of the thermostat or coolant temperature sensor 5 A replacement of the spark plugs 6 A cleaning of the oxygen sensors and mass air flow sensor
What does p0172 GMC stand for in engine code?

When to run the p1128, p1129 code?
P1128, P1129 code – This diagnostic runs when the following condition are met, shortly after engine start up, fuel level above 12%, battery voltage above 11. volts, no active bank 1 fuel injector, ignition coil, or upstream O2 sensor circuit faults.
How to diagnose p1128 Dodge closed loop fueling?
Start by checking the battery charge and terminals, and alternator charging. If the battery and alternator are OK, the Totally Integrated Power Module may be damage. What does this mean? The cost of diagnosing the P1128 DODGE code is 1.0 hour of labor.

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’s the problem with my 2006 Lexus GS300?
The 2006 GS3000 is prone to a complicated fuel trim and oxygen sensor issue, and the repair for this issue is even more complicated. CARspec recommends that, if you’ve got P0301, P0302, P0303, P0304, P0305, P0306 or a rough running engine, you read this first. The issue addressed in this blog centers around the following codes for the 2006 GS300:
Can a stuck fuel pressure regulator cause a rich condition?
Pay special attention to the fuel pressure regulator and the fuel injectors. If the fuel pressure regulator is stuck, it can cause a rich condition due to the high pressure. If the fuel injectors are faulty, they could leak fuel into the cylinders rather than delivering the precise amount needed for the air-fuel ratio.

What happens if your DTC p0172 goes into limp home mode?
Depending on the nature of the failure, DTC P0172 may or may not be accompanied by drivability issues. At the very least, you will experience poor fuel economy, because, with the ECU in “limp-home mode,” it is no longer looking at HO 2 S and AFR sensors for feedback.
