Decoding the P0174 Code in Your Ford: Causes and Solutions
After buying your Ford, you may eventually get a trouble code reading of P0174. This is a code that indicates your engine is running lean.
To help you diagnose and repair this issue, in this article, we will discuss the causes and solutions of a P0174 code in your Ford.

This way, you can be sure that the parts and tools used in the repair process are of high quality and also reliable.
What's the Meaning of the P0174 Code in Your Ford?
The P0174 code stands for a “System Too Lean (Bank 2)” error. Bank 2 refers to the side of the engine that doesn't contain cylinder 1.
This means there is an imbalance in the air/fuel ratio, and too much air is entering the combustion chambers, which causes your engine to run lean.
Most Common Causes of a P0174 Code in Your Ford
The most common causes of a P0174 code on your Ford are:
Poor air/fuel Mixture
When the air/fuel ratio is too lean, it can cause a P0174 code. This means there's not enough fuel to balance with the air entering the combustion chambers. Normally, this can be caused by a faulty fuel injector, a vacuum leak, or a malfunctioning oxygen sensor.
Intake Manifold Gasket Problems
Over time, an intake manifold gasket that has degraded can lead to air leaks. This causes the car engine to run lean and triggers the P0174 code.
Vacuum Leak
A vacuum leak can allow air to enter the intake manifold, making the engine lean. Such a leak can be due to a broken hose or a faulty gasket.
Faulty Mass Air Flow Sensor
A faulty MAF sensor can also cause an air/fuel ratio imbalance, resulting in a P0174 code.
Fuel Pressure Regulator Failure
If the fuel pressure regulator is too low or restrictive, it can cause an imbalance in the air/fuel ratio, resulting in a P0174 code.
Best Solutions for Fixing a P0174 Code on Your Ford
The solutions to a P0174 code on your Ford will depend on the cause of the problem. But here are some standard solutions:
1. Check and Replace any Faulty or Degraded Parts
Make sure to check the intake manifold gasket, fuel injectors, oxygen sensor, and mass air flow sensor for any faults.
2. Diagnose Vacuum Leaks
Check all hoses, including vacuum hoses and connections going into the intake manifold, for any signs of a leak.
3. Replace the Fuel Pressure Regulator
This component is responsible for maintaining the proper fuel pressure in the system. If it's damaged or not functioning correctly, replace it with one compatible with your Ford model.
4. Use an OBD-II Scanner
With the help of an OBD-II scanner, you can read and reset the code from your Ford's ECU system. This scanner can also help you identify any other underlying issues with your engine.

Frequently Asked Questions
What is the P0174 code?
The P0174 code stands for a "System Too Lean (Bank 2)" error. Bank 2 refers to the side of the engine that doesn't contain cylinder 1. This means there is an imbalance in the air/fuel ratio, and too much air is entering the combustion chambers, which causes your engine to run lean.
What are the most common causes of a P0174 code?
The most common causes of a P0174 code on your Ford are poor air/fuel mixture, intake manifold gasket problems, vacuum leaks, faulty mass air flow sensor, and fuel pressure regulator failure.
What are the best solutions for fixing a P0174 code?
The solutions to a P0174 code on your Ford will depend on the cause of the problem, but some standard solutions include checking and replacing any faulty or degraded parts, diagnosing vacuum leaks, replacing the fuel pressure regulator, and using an OBD-II scanner.
How much does it cost to repair the P0174 code?
The repair cost depends on the problem's cause and severity. Contact a qualified technician at Goodhood for an accurate quote.
What's the oxygen sensor?
The oxygen sensor is a device that measures the amount of oxygen in your exhaust and sends it to your Ford's ECU, which then adjusts the air/fuel ratio accordingly. This helps maintain optimal engine performance and fuel efficiency. An issue with this sensor can cause your Ford to run lean, resulting in a P0174 code.
What's the MAF sensor?
The mass airflow (MAF) sensor is a device that measures the amount of air entering your engine and sends it to your Ford's ECU. This helps the ECU calculate the proper fuel injection for optimal performance. A faulty MAF sensor can cause an imbalance in the air/fuel ratio, resulting in a P0174 code.
What do I do if the code returns after replacing the MAF sensor?
If the code returns after replacing the MAF sensor, it's likely due to a vacuum leak somewhere in your Ford. Check all hoses and connections going into the intake manifold gasket for any signs of a leak. If there is no leak, then the issue may be with the fuel injectors or oxygen sensors. Contact a qualified technician to properly diagnose and repair your vehicle.
How often should I check my fuel system?
It's recommended to check your fuel system once every 8,000-10,000 miles. If you encounter any issues with the fuel system, contact a qualified technician at Goodhood to properly diagnose and repair your vehicle. This way, you can be sure that the parts and tools used in the repair process are of high quality and also reliable.
Does the fuel pressure regulator affect the P0174 code?
Yes, if the fuel pressure regulator is too low or restrictive, it can cause an imbalance in the air/fuel ratio, resulting in a P0174 code. So, if you encounter this issue, make sure to check and replace your fuel pressure regulator.
