The electrical current needed is regulated from an electrical ignition switch. The control switch can pull the diaphragm down, allowing the fuel to rush into the carburetor, or pull the diaphragm up, causing pressure to push the fuel out.Įlectric fuel pumps send a positive electrical current through the fuel lines causing enough force to send fuel to the engine. The camshaft operates a switch on the fuel pump that uses a diaphragm situated inside the carburetor. Mechanical fuel pumps are outside of the fuel tank. The fuel mixes with air inside the carburetor, the liquid is then pumped into the engine. Mechanical fuel pumps move fuel from the fuel tank to the engine under low pressure through the carburetor. Engines require a constant fuel supply, and the fuel pump is the system used to provide it. Thank you.Car engines are intriguing machines assembled with several systems built to deliver optimal performance.

Air Filter– While it’s not the most common reason to throw the P0175 code, a clogged air filter certainly can cause the code to throw.If the fuel pressure is off, atomization doesn’t happen properly and the optimal air/fuel mixture isn’t achieved. Fuel Pump/Fuel Filter– Today’s modern fuel injected motors need a lot of fuel pressure to atomize the gas properly.Bad Fuel Injectors– If you have one or more fuel injectors that have gone bad that can certainly cause the air/fuel mixture to go bad.If it has gone bad, the air fuel mixture will be off and the P0175 code will show. Mass Air Flow Sensor– The mass air flow sensor calculates the volume of air entering the engine.This will cause the Expedition to run rich. The computer will still adjust the air/fuel mixture to compensate. When the oxygen sensor is bad, it can cause a false reading and trigger the code. O2 Sensor– The P0175 codes is thrown when the oxygen sensor(s) do not register the right amount of oxygen in the exhaust.

Here’s a great YouTube video on how to find a vacuum leak. Take a look around and see if you can find the vacuum leak. Vacuum Leaks– With the Ford Expedition, one of the most common cause for the P0175 code to be thrown is a vacuum leak.Here are the most common causes of P0175:

This youtube video is a great resource for diagnosing the P0175 trouble code in your Expedition.

Fouled Spark Plugs– The spark plugs can foul if the engine runs very rich for a long enough period of time.

Exhaust Smell/Color– Depending on how rich the motor is running, there could be some exhaust odor or discoloration.

Idle Issues– With the air/fuel mixture altered, the vehicle can idle erratically as the computer compensates to keep the engine running.

Misfire– If the air fuel mixture has gotten too far from factory specs, this can cause the Expedition to misfire.

Mileage- may or may not suffer depending on how much the air fuel mixture has changed.

Here are the typical symptoms that something is wrong when you have code P0175. For most people the first sign that anything is wrong at all is the service engine soon light coming on. There aren’t usually any drivability issues associated with P0175. Typically the code will be triggered by a rich condition in the engine. The P0175 code on a Ford Expedition will often be thrown if the fuel injection system is not operating properly. This would be the opposite of a lean condition, which’ll throw P0174. Bank 2 refers to the rich condition being detected on the side of the engine with cylinder two.Ī rich condition indicates that the air fuel mixture has too much fuel or not enough air. P0175 is thrown when the oxygen sensors detect that the air fuel mixture is too rich. It means that the motor is running with a rich condition. It’s not the most complicated OBDII trouble code to diagnose. This code number references a number that is given to you when you plug a vehicle into an OBDII scanner. A common trouble code with the Ford Expedition is P0175.
