SOURCE: Want to know what PO172 System too rich bank 1

it means your cars computer is pumping too muchgas into your motor because it thinks the engine is either running lean possibly due to faulty o2 sensors or that the coolant temp sensor is giving false readings and the ecm thinks the car is still too cold.

SOURCE: 2002 6 cylinder 3.o engine Ford Ranger. Cold start

Changed the air filter lately? Possibly defective O2 sensors, but I doubt it. If air filter and intake are clear, I'd check barometric pressure sensor and mass air flow sensors. Get a Haynes or Chilton's for $25 at Pep Boys for instructions on testing these componenets

What should i do about my car engine light is on they check the code and show po175 and po172


It means there is too much fuel in the air/fuel mix going into the engine. You can drive to a repair shop without too much trouble. A lean mix is much more dangerous, but you will use a ton of fuel and not get much power if the mix is too rich.

The real problem is why is the computer putting to much fuel in the mix. Maybe the carburetor is bad, maybe the computer or one of the sensors is shot. Either way, get a good mechanic to figure out what is wrong.

I have a 1997 1500 with a 5.0 Im getting codes po143 po172 po175 and po300. Im not sure what the cause could be.


Code 300 is for a random miss.
172 and 175 are for the same problem - 172 is for a rich fuel mixture bank one and 175 is for the fuel mixture too rich on bank two.
Code 143 is for a rich mixture for sensor number 3.
All of the codes could be connected to a leaking injector or other fuel problem. Very seldom are all of the O2 sensors faulty at the same time.

V6 tracker po172 and po175


The codes are for the O2 sensors telling the computer the fuel mixture is too rich. One code for each side of the engine.
When this happens, the computer tries to turn down the injectors which makes the engine run too lean.
Since you have a code for both sides, I doubt the sensors are faulty. You probably have a real problem with the fuel mixture.
You would need to check fuel pressure and look for fuel leaks into the cylinders.

PO172 AND PO175 CODES


These codes mean system too rich, meaning too much fuel while running, I would check the vacuum lines and then clean the Mass Air Flow sensor (MAF), it should be located in line with the air intake tube from the air filter. Be careful not to damage the sensors internal components (use electrical cleaner or brake cleaner), and make sure it is dry before re-installation. Hope this helps, let me know.

Obd II po172 code on ford explorer


P0172 is a fuel system always rich code, on most explorers I have found the Mass Air Flow sensor is the root cause of the problem.
