It is important to consult a mechanic or a Toyota dealer with your Vehicle Identification Number (VIN) to get specific information about your Corolla model.

The fuel tank pressure sensor is located on top of the fuel tank

The fuel tank pressure sensor is an integral part of your car's evaporative emissions system, also known as EVAP. This system is designed to keep all gasoline vapors within your car's fuel system after fuelling up at the gas station. The sensor monitors the pressure, both positive and negative, inside the fuel tank. This pressure monitoring helps to identify leaks in the fuel system, alert you to a defective gas cap, signal the engine computer that the EVAP system is operating properly, regulate fuel consumption, and maintain compliance with emissions regulations.

If you suspect that your fuel tank pressure sensor is faulty, you should get it checked out by a mechanic. A bad sensor will trigger the check engine light, and while this could be due to a variety of issues, it is best to be safe and get it inspected. Some signs that your fuel system has a pressure problem include increased fuel consumption, a loss of power and acceleration, black smoke coming out of the tailpipe, gasoline dripping from the tailpipe, and a rough-running engine.

It is important to note that the fuel tank pressure sensor cannot be repaired if it has gone bad; it must be replaced. This job is best left to a professional repair shop due to the dangers of working with automotive electronics and fuel systems.

It's part of the fuel pump assembly

The fuel tank pressure sensor in a Corolla is part of the fuel pump assembly. It is usually located on or near the fuel tank, often near the charcoal canister assembly or the fuel pump. In some cases, it may be in a remote location.

The sensor is responsible for measuring the vapor pressure in the evaporative emission control system. It uses a silicon chip with a calibrated reference pressure on one side, while the other side is exposed to the vapor pressure. This chip is sensitive to small changes in pressure, and as the vapor pressure increases, the voltage signal to the ECM also increases.

When the sensor is mounted directly on the fuel pump assembly, no hoses are required. However, for remote locations, the VPS may have one or two hoses connected to it. It is important to ensure that these hoses are connected to the proper ports, as reversing them can lead to issues.

To access the fuel tank pressure sensor in a Corolla, you may need to remove the rear seat and the plate that covers the fuel pump assembly. The procedure may vary slightly depending on the model year of your Corolla.

It's under the rear seat

The fuel tank pressure sensor in a Toyota Corolla is located under the rear seat. To access it, you need to remove the rear seat and then the plate that covers the fuel pump assembly. Depending on the model year of your Corolla, you may need to remove screws or bolts to take off the plate. Once you have removed the plate, you will see the fuel tank pressure sensor on top of the fuel pump assembly unit.

It is important to note that the location of the fuel tank pressure sensor may vary depending on the model year of your Toyota Corolla. For example, for the 2003-2005 models, the fuel tank pressure sensor is located on the fuel tank, near the charcoal canister assembly. In contrast, for the 2014 model, the sensor is accessed by removing the rear seat and exposing the gas tank. Therefore, it is always a good idea to consult a mechanic or the vehicle's repair manual for specific instructions and diagrams for your particular model.

The fuel tank pressure sensor is an integral part of your car's evaporative emissions system, also known as EVAP. This system is designed to keep all gasoline vapours within your car's fuel system after fuelling up at the gas station. The sensor monitors both positive and negative pressure inside your fuel tank, helping to identify leaks in the fuel system, alert you to a defective gas cap, and signal the engine computer that the EVAP system is operating properly.

If you suspect an issue with your fuel tank pressure sensor, several signs can indicate a problem. These include an illuminated check engine light, increased fuel consumption, a loss of power and acceleration, black smoke coming from the tailpipe, gasoline dripping from the tailpipe, and a rough-running engine. If you notice any of these symptoms, it is essential to have your vehicle checked by a qualified mechanic as soon as possible.
