How much does it cost to fix a P0172 code?
Usually, replacing the sensor should not cost you more than $60.00. However, if the problem was left for a longer time frame, you might introduce them into the catalytic converter, which can cost you easily up to $3000 if not more in more modern vehicles.
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 mean on a fuel system?
When the error code shows fuel system too rich, this means the computer pulls back more and more fuel, which will be called long term fuel trim in the long run. Ideally, this should be around 1% to 2%. When P0172 is set, the means the fuel trim is somewhere around -15% or even as low as -30% compensated.

How can I fix code p0171?
To fix the P0171 code, you need to check and repair vacuum leaks, repair low fuel pressure, or replace any faulty sensor that can cause a lean mixture on bank 1. What causes P0171 code? The most common causes of the P0171 code are vacuum or intake leaks, low fuel pressure, faulty PCV valve, or a faulty MAF sensor.
What causes trouble code p0172?
A Thermostat stuck in the open position can mechanically cause a code P0172, especially in cold climates. The engine won’t warm up, preventing it from going into “closed loop” fuel control. Ignition misfires, like mechanical misfires, cause puffs of oxygen to keep hitting the Oxygen Sensors.
