The fuel tank pressure sensor in a Chevrolet Silverado 1500 plays a crucial role in reducing the vehicle's environmental impact. It detects the pressure inside the fuel tank, helping to identify leaks and reduce fuel vapour emissions. While the sensor is designed to last, it may eventually need to be replaced. This can be done by carefully troubleshooting the issue, acquiring a replacement sensor, and installing it by removing all connectors, cleaning the surface, and connecting the new sensor. The cost of the replacement sensor varies depending on the brand and retailer, ranging from $46.99 to $13502903.
What You'll Learn
The fuel tank pressure sensor helps control fuel vapour emissions
The fuel tank pressure sensor is an integral part of the evaporative emissions system (EVAP) in modern vehicles. It plays a crucial role in reducing the environmental impact of cars by minimising fuel vapour emissions and preventing fuel wastage.
The sensor is strategically mounted on top or inside the fuel tank to monitor pressure and detect leaks in the fuel system. This includes leaks from the gas cap or anywhere else in the system, including the lines. By doing so, the sensor helps contain fuel vapours within the EVAP system, preventing their escape into the atmosphere.
When the sensor detects a leak or if it malfunctions, it alerts the driver by illuminating the "check engine" light. This warning sign is triggered because the sensor is connected to the vehicle's engine control unit (ECU). Mechanics can then use a scanner to read the trouble code and pinpoint the issue, whether it's a leak in the evaporative emissions system or a faulty sensor.
The fuel tank pressure sensor is not just an environmental safeguard but also a safety measure. Fuel vapours escaping from unsealed fuel tanks can lead to air pollution through chemical reactions and even pose a combustion risk due to static electricity. To address this, regulations worldwide mandated the use of sealed fuel tanks and fuel tank pressure sensors.
In summary, the fuel tank pressure sensor is a critical component in modern vehicles, helping to control fuel vapour emissions, ensuring environmental compliance, and enhancing safety by minimising the escape of combustible fuel vapours.

The sensor constantly reads pressure in the fuel tank
The fuel tank pressure sensor plays a crucial role in reducing the environmental impact of vehicles. It does so by detecting the pressure inside the fuel tank, which helps identify leaks in the system, including the gas cap and lines. This sensor is connected to the vehicle's ECU and illuminates the check engine light when it detects a problem.
The sensor constantly reads the pressure in the fuel tank to ensure the tank is sealed and to provide fuel-related data to the ECU. This data includes information about fuel usage, which helps the ECU dictate the fuel supply to the vehicle. An issue with the fuel tank pressure sensor can lead to incorrect calculations by the ECU, resulting in a lean air-fuel mixture and affecting the vehicle's ability to start up or run smoothly.
If the sensor reports unexpected pressures, the check engine light will be illuminated, indicating a potential problem with the EVAP system. This system is designed to collect vaporized fuel and use it for combustion, reducing the environmental impact of fuel vapors.
While a faulty fuel tank pressure sensor is not an emergency, it can cause complications such as reduced fuel efficiency and trouble starting the vehicle. It is recommended to scan error codes regularly and seek professional assistance for EVAP system issues due to the risk of fire and the potential complexity of diagnosis.

The sensor can be replaced without disconnecting the fuel/EVAP lines
If you want to replace the fuel tank pressure sensor on your Chevy Silverado 1500 without disconnecting the fuel/EVAP lines, you can do so by lowering the tank. This can be done by using a floor jack to support the tank and lower it, without having to disconnect any hoses.
The amount you can lower the tank will depend on the hoses and other items attached to the fuel tank, as well as the filler neck, which will prevent it from dropping too far. However, the filler neck should still flex enough to allow for some lowering of the tank. According to one user, the tank can be lowered by about 4 inches without disconnecting any hoses, which was enough to easily remove and replace the fuel tank pressure sensor. Another user commented that the tank can be lowered by at least 6 inches without disconnecting the fuel/EVAP lines and electrical connections.
Before attempting any repairs, it is important to ensure you have the correct parts for your vehicle and take the necessary safety precautions.

The sensor can be purchased for as little as $46.99
The fuel tank pressure sensor in your Chevrolet Silverado 1500 plays a crucial role in reducing your vehicle's environmental impact. By detecting the pressure inside the tank, it can identify leaks and prevent fuel vapour from escaping into the atmosphere. Unfortunately, reports indicate that almost every model year of the Chevrolet Silverado, up until 2019, has experienced issues with fuel tank pressure sensor failure.
When the sensor malfunctions, it can cause various problems, including reduced fuel efficiency and trouble starting your truck. In some cases, it may even lead to stalling. While this issue is not an emergency, it is essential to address it promptly to avoid further complications and ensure optimal performance.
The good news is that replacing the fuel tank pressure sensor is a straightforward process, and you have a range of options to choose from. The sensor can be purchased for as little as $46.99, with prices varying depending on the brand and retailer. Some popular choices include the ACDelco EVAP Fuel Tank Pressure Sensor, the Santech EVAP Fuel Tank Pressure Sensor, and the Duralast EVAP Fuel Tank Pressure Sensor, all of which are available at various online and in-store retailers. These sensors offer limited lifetime warranties and are designed to fit your Chevrolet Silverado 1500, ensuring you get back on the road safely.
Once you have purchased the replacement sensor, you can either install it yourself or seek the assistance of a professional technician. If you choose to tackle the task yourself, make sure to take the necessary precautions, especially when working with fuel, as there is a risk of fire. Always disconnect the battery before beginning any repairs.
