Replacement Guide: 2005 Expedition Fuel Tank Pressure Sensor

If you're looking to replace the fuel tank pressure sensor on your 2005 Ford Expedition, you're in the right place. This is a job that can be done at home, but it's important to know what you're doing. The fuel tank pressure sensor is located in the Evap line above the fuel tank, and it may be necessary to drop the tank to gain access to the sensor. However, some people have reported being able to replace the sensor without dropping the tank, so it's worth exploring your options before you begin.

The sensor is in the EVAP line above the fuel tank

To replace the fuel tank pressure sensor on a 2005 Expedition, you will need to access the sensor, which is located in the EVAP line above the fuel tank. This will require dropping or lowering the tank to gain access to the sensor. Here is a step-by-step guide on how to do it:

First, make sure you have the necessary tools and safety equipment, such as a jack, safety gloves, and eye protection. Place the vehicle on a flat, level surface and engage the parking brake. Loosen and remove any bolts or straps holding the fuel tank in place. Carefully lower the tank using a jack or lift, ensuring you do not damage any nearby components. Once you have enough clearance, locate the fuel tank pressure sensor in the EVAP line above the tank. Disconnect the sensor's wire connector and remove it from the fuel pump assembly. Install the new sensor, reconnect the wire, and secure it in place. Finally, raise the fuel tank back into position and reattach any bolts or straps. Ensure everything is securely connected and the area is clean before closing up.

It is important to note that working with automotive electronics and fuel systems can be dangerous, so if you are uncomfortable with any part of the process, it is best to consult a professional repair shop or a mechanic. Additionally, having a second person to assist you during the process can be helpful.

Before beginning the replacement, it is recommended to consult a repair manual or seek advice from a mechanic to ensure you have the correct tools and safety procedures in place. Additionally, some people have suggested removing the spare tire to provide more room to work.

The tank must be dropped to access the sensor

The fuel tank pressure sensor on a 2005 Expedition is located on top of the fuel pump module, which is mounted on top of or inside the fuel tank. To access the sensor, you will need to drop the fuel tank. Here's a step-by-step guide on how to do this:

Before beginning, make sure you have the necessary tools and safety equipment, including gloves and eye protection. It is also recommended to work in a well-ventilated area to avoid inhaling fumes.

• Park your vehicle on a level surface and engage the parking brake. Place wheel chocks around the wheels for added safety.
• Remove the fuel tank cap to relieve any pressure inside the tank.
• Locate the fuel tank and identify the straps or brackets holding it in place. You will need to loosen or remove these to lower the tank.
• Place a drain pan or container under the fuel tank to catch any residual fuel.
• Disconnect the fuel lines and electrical connections to the fuel pump. Be careful not to spill fuel and ensure that there are no open flames or sparks nearby.
• Carefully lower the fuel tank using a jack or hoist. Lower it just enough to access the fuel pump module and sensor.
• Once the tank is lowered, locate the fuel pump module and the sensor on top of it.
• Disconnect the electrical connector from the sensor.
• Remove the sensor by turning it counterclockwise or as per the manufacturer's instructions.
• Install the new sensor by aligning it with the fuel pump module and turning it clockwise to lock it into place.
• Reconnect the electrical connector to the new sensor.
• Carefully raise the fuel tank back into position and secure it with the straps or brackets.
• Reattach the fuel lines and electrical connections to the fuel pump.
• Tighten all connections and check for any leaks.
• Close the fuel tank cap and start the engine to test the new sensor.

It is important to work cautiously when handling fuel and electrical components. If you are unsure or uncomfortable with any part of the process, it is recommended to consult a professional mechanic.

The FTP sensor is moulded into the plastic vapour hoses

The Fuel Tank Pressure (FTP) sensor is located in different places depending on the make and model of the vehicle. In some cases, the FTP sensor is moulded into the plastic vapour hoses. If this is the case, you will need to locate the vapour hose connected to the FTP sensor. This hose can usually be found near the charcoal canister assembly or the fuel tank.

Once you have located the vapour hose, you can proceed to disconnect it from the FTP sensor. This is typically done by pressing the release tab and gently pulling the hose apart. Be sure to note how the hose is positioned and connected for proper reinstallation.

When you are ready to install the new FTP sensor, attach it to the mounting location and ensure it is properly aligned. Secure the sensor with any retaining hardware, following the torque specifications provided by the vehicle manufacturer.

Finally, reconnect the vapour hose to the new FTP sensor by aligning it correctly and pushing it together until you hear a click, indicating that it is securely in place.

It is important to note that working on fuel system components can be dangerous, and it is always best to consult a qualified mechanic or seek professional assistance if you are unsure about any part of the process.

The sensor is located at the top of the tank

The fuel tank pressure sensor is located at the top of the tank. It is part of the fuel pump assembly and is mounted on top of the tank or inside the tank. It is part of the evaporative emissions system (commonly referred to as "EVAP") and reads pressure in the fuel system to detect evaporative leaks, such as a loose or faulty gas cap.

To replace the fuel tank pressure sensor, you will need to disconnect the wire, remove the sensor from the top of the fuel pump, install the new sensor, and reconnect the wire. In some cases, it may be necessary to lower the tank to access the sensor. However, in other cases, it may be possible to access the sensor without lowering the tank by removing the spare tire and using ramps to get additional clearance.

It is important to note that the process of replacing the fuel tank pressure sensor may vary depending on the specific make and model of your vehicle. Always refer to your vehicle's repair manual or seek advice from a qualified mechanic if you are unsure about the procedure.

Additionally, the fuel tank pressure sensor is connected to the engine computer, and when the sensor detects a leak, or if the sensor itself fails, it illuminates the "check engine" light. Mechanics can read a trouble code to trace it to a leak in the evaporative emissions system or the sensor.

The sensor is at the back of the tank

To replace the fuel tank pressure sensor on a 2005 Ford Expedition, you will need to locate the sensor, which is at the back of the tank.

First, you will need to remove the spare tire and place your vehicle on ramps or jack stands to gain access to the underside of the vehicle. Once you have located the sensor at the back of the tank, you can disconnect the wire connector and remove the sensor by turning it a quarter turn to the right. Install the new sensor by plugging in the wire connector and turning it a quarter turn to the left to lock it in place.

In some cases, you may need to lower the fuel tank to access the sensor. This can be done by following the procedure outlined in the repair manual or by seeking assistance from a mechanic or auto repair shop.

It is important to note that working on fuel system components can be dangerous, so it is recommended to exercise caution and refer to the appropriate repair manuals or seek professional help if you are unsure about any steps.
