Ford Error Code P0171 is an error code that is associated with the fuel system. The code is triggered when the fuel system does not have enough oxygen to run the engine properly. This can be caused by a number of factors, including a clogged air filter, a faulty oxygen sensor, or a problem with the fuel injection system.
If you experience this error code, there are a few things you can do to troubleshoot the problem. First, check the air filter to make sure it is not clogged. If it is, clean or replace it. Next, check the oxygen sensor to make sure it is not faulty. If it is, replace it. Finally, check the fuel injection system to make sure it is working properly. If it is not, have it repaired.
If you are unable to fix the problem yourself, take your vehicle to a qualified mechanic for further diagnosis and repair.

How do you fix code P0171?
A code P0171 may mean that one or more of your engine’s cylinders are not firing properly. In order to fix code P0171, you may need to clean the MAF sensor, replace the fuel filter, and/or replace the spark plugs.
How much does it cost to fix P0171 code?
The P0171 code is a problem with the car’s air-fuel ratio. It can be caused by a number of things, including a faulty oxygen sensor or a vacuum leak. The code will usually trigger a “check engine” light, and the car’s performance may also be affected.
There is no one-size-fits-all answer to the question of how much it costs to fix the P0171 code. The cost will depend on the specific cause of the code and the extent of the necessary repairs. However, it is generally a relatively expensive repair, and may cost several hundred dollars.
If you are experiencing problems with your car and the P0171 code is triggering the “check engine” light, it is important to take it to a qualified mechanic for diagnosis and repairs. Trying to fix the code yourself can be risky and may end up costing more in the long run.
What does P0171 bank 1 system Too Lean Mean?
P0171 bank 1 system too lean means that the fuel mixture is too lean (too much air, not enough fuel) in the first bank of cylinders. This code is set when the computer detects that the fuel mixture is too lean for more than 5 seconds.
Possible causes of a P0171 code include a vacuum leak, a bad MAF sensor, a bad fuel pump, a plugged fuel filter, or a faulty ignition coil.
If your car has a P0171 code, you should have it checked out by a qualified technician as soon as possible.
Can you drive with P0171 code?
Can you drive with P0171 code?
This is a question that a lot of people may have when they see the P0171 code. The P0171 code is a code that is set when the engine has a lean condition. This code is set when the air/fuel mixture is too lean. When this code is set, it will cause the engine to run rough and it will also cause the engine to stall.
So, can you drive with the P0171 code?
Well, it depends on the severity of the code. If the code is severe, then you will not be able to drive the vehicle. If the code is not severe, then you may be able to drive the vehicle, but you will need to have the code checked and cleared.
What could cause a P0171 code?
A P0171 code is indicative of a lean condition on the vehicle. This code is set when the fuel mixture is too lean for too long. There are a few things that could cause this code to set.
One possibility is a vacuum leak. If there is a leak in the vacuum system, it can cause the engine to run lean. A leak in the intake manifold gasket, the vacuum hose, or the PCV valve can all cause a vacuum leak.
Another possibility is a dirty air filter. A dirty air filter can restrict airflow and cause the engine to run lean.
A defective oxygen sensor can also cause a lean condition and set a P0171 code.
If the engine is running too lean, it can cause damage to the engine. It’s important to address the cause of the lean condition as soon as possible to avoid any damage.
Can a dirty air filter cause a P0171 code?
Can a dirty air filter cause a P0171 code?
A dirty air filter can cause a P0171 code. A P0171 code is a code that is set when the engine is running too lean. A dirty air filter can cause the engine to run too lean because it can restrict the air flow into the engine. When the air flow into the engine is restricted, the engine is not able to get enough air to the cylinders, which causes the engine to run too lean.
Can a bad O2 sensor cause a P0171 code?
A P0171 code is often caused by a bad oxygen sensor. The oxygen sensor is responsible for reading the amount of oxygen in the exhaust system. If it is not working correctly, it can cause the engine to run too rich or too lean. This can cause a variety of problems, including a P0171 code.
If you are experiencing problems with your engine and you think a bad oxygen sensor may be the cause, you should have the sensor checked by a qualified technician. If the sensor is found to be bad, it will need to be replaced.
