Replacing The Fuel Tank Pressure Sensor In A 2005 Expedition

The fuel tank pressure sensor in a Ford Expedition is located in the Evap line above the fuel tank. The tank must be dropped to access the sensor. The sensor is moulded into the plastic vapour hoses attached to the fuel tank. The replacement procedure involves disconnecting the wire, removing the sensor from the top of the fuel pump, installing the new sensor, and reconnecting the wire.

The sensor is in the evaporative emission (EVAP) line above the fuel tank

The fuel tank pressure sensor is an essential component of the evaporative emission (EVAP) system in your 2005 Expedition. This system plays a crucial role in preventing fuel vapours from escaping into the atmosphere, reducing both pollution and fuel evaporation from the engine and fuel tank.

The sensor is located in the EVAP line above the fuel tank. To access it, you'll need to remove the spare tire and, possibly, lower the tank. It's a relatively small component, so you may have enough room to reach it without dropping the tank, but some models may require lowering the tank even just a little bit. It's also recommended to remove the drive shaft to give yourself more room to work.

Once you have access to the sensor, the replacement process is straightforward. First, disconnect the wire connector from the old sensor. Then, give the sensor a quarter turn to the right and lift it out. Now, you can plug the connector into your new sensor, place it, and turn it a quarter turn to the left to lock it in place.

After securing the new sensor, you can reconnect the wire and raise the tank, if you lowered it. Don't forget to reattach the spare tire as well.

The fuel tank must be dropped to access the sensor

The fuel tank pressure sensor in a 2005 Ford Expedition is located on top of the fuel pump module, which is mounted on top of or inside the fuel tank. This means that, to access the sensor, the fuel tank must be lowered.

There are a few ways to go about this. One method is to use a garage with a lift and jack to lower the tank. Another option is to drive the vehicle onto ramps to gain access to the underside of the car. The tank can then be lowered using tie-downs.

Once the tank is lowered, the sensor can be disconnected and removed. The process involves disconnecting the wire, turning the sensor, and lifting it out. The new sensor can then be installed, turned to lock it in place, and the wire can be reconnected.

It is important to note that working with automotive electronics and fuel systems can be dangerous. Therefore, it is recommended to leave this task to a professional mechanic to lessen the chances of damage or malfunction.

The FTP sensor is moulded into the plastic vapour hoses attached to the fuel tank

The fuel tank pressure (FTP) sensor on a 2005 Ford Expedition is moulded into the plastic vapour hoses attached to the fuel tank. This means that the sensor is not a separate, removable unit, and cannot be replaced on its own. Instead, the entire evaporative hose component must be replaced as a single unit, along with the FTP sensor.

To access the sensor, the fuel tank will need to be removed from the vehicle. This can be done by first removing the gas tank shroud and loosening the front and rear gas tank straps, leaving one full nut. This will allow the tank to be lowered enough to access the sensor and hoses. It is important to note that there is no fuel in these lines, only vapour, so there is no need to drain the tank.

When replacing the FTP sensor, it is recommended to purchase a new line/sensor assembly, as this will come with a plastic shroud that covers the sensor and protects it from contamination. The new shroud is an admission of poor design by Ford, as it indicates that they are aware of the issue of oil contamination causing sensor failure.

The process of replacing the FTP sensor involves disconnecting the electrical connector and vapour hoses from the sensor, and then attaching the new sensor and hoses. It is important to ensure that the hoses are connected to the proper ports, as reversing them can cause issues. Additionally, it is recommended to practice disconnecting and reconnecting the connectors on a workbench to familiarise yourself with the process before attempting it on the vehicle.

Overall, replacing the FTP sensor on a 2005 Ford Expedition is a relatively straightforward process that can be completed in a few hours. However, it is important to take precautions and follow the proper steps to ensure a successful repair.

Disconnect the wire, remove the sensor from the top of the fuel pump, install the new sensor, and reconnect the wire

To replace the fuel tank pressure sensor on a 2005 expedition, follow these steps:

First, disconnect the wire from the sensor. This should only require a quarter turn to the right. Then, remove the sensor from the top of the fuel pump. Depending on your vehicle, you may need to lower the tank or remove the drive shaft to access the sensor. In some cases, it may be possible to access the sensor by removing the spare tire and using ramps to get additional clearance.

Next, install the new sensor. Ensure that the O-ring is lubricated with a small amount of Vaseline to make the installation easier. Finally, reconnect the wire to the new sensor and turn it a quarter turn to the left to lock it in place.

It is important to note that working with fuel can be dangerous, so always take the necessary precautions and consider seeking professional assistance if you are uncomfortable with any part of the process.

The sensor is located at the front or back of the tank

The fuel tank pressure sensor is located above the fuel tank. It is built into the fuel pump assembly, which is located at the front or back of the tank.

To replace the sensor, you will need to disconnect the wire connector and remove the old sensor by turning it a quarter turn to the right. You can then install the new sensor and turn it a quarter turn to the left to lock it in place. Finally, reconnect the wire.

In some cases, you may need to lower the fuel tank to access the sensor. This can be done by following the procedure for dropping the tank, which is available in various repair manuals and forums. However, in some cases, it may be possible to access the sensor without lowering the tank. For example, by removing the spare tire and using ramps to raise the vehicle, you may be able to gain enough clearance to reach the sensor.
