- Replacing one or more oxygen sensors.
- Replacing the mass air flow sensor.
- Repairing a vacuum leak.
How do you fix a fuel mixture imbalance?
Rehabilitate the leakages in the engine exhaust. Carefully adjust the faults in the mass air flow or manifold air pressure sensor. The blocked fuel filter should be restored to working order. Adjust the flawed fuel pump.
What does too rich bank 1 Code mean?
This ensures the engine generates the most amount of power possible with the least amount of fuel. If the engine control unit detects the bank 1 cylinder is “too rich,” it means it has too much fuel and not enough in oxygen. The symptoms of trouble code P0172 are usually the same symptoms of an engine running rich.
What causes a fuel system too rich code?
A saturated carbon canister due to packing the fuel tank. Faulty O2 sensor (but O2 sensors more commonly fail by reading lean, not rich). A clogged air filter can cause code P0172. What are the Common Symptoms of the P0172 Code?
What does Bank 1 mean in engine code?
The “Bank 1” portion of this code indicates that the problem is concentrated on the side of the engine that includes the #1 cylinder. Since inline four cylinders only have one bank, the one bank they do have is considered bank 1.
What does it mean when your engine is too rich?
The ECU has the ability to slightly adjust the air-fuel ratio if it is rich. However, if the margin of compensation is too large, then a P0172 code will likely set. The term “rich” in this case means that there is too much gasoline and not enough oxygen detected in the air-fuel ratio of the engine.
