How does the fuel tank pressure sensor work?

The sensor constantly reads pressure in the fuel tank, and is essential in testing the evaporative emissions (EVAP) system for leaks. The vehicle's computer expects a certain range of pressure in the fuel tank at any given time. If the sensor reports pressures that are unexpected, the computer will turn on the check engine light.

What are the symptoms related to a bad fuel tank pressure sensor?

The check engine light will illuminate any time there is an EVAP problem. Also, in some models, there may be a popping sound accompanying the check engine light, as the leak detection pump continuously attempts to pressurize the fuel tank.

Can I drive with a fuel tank pressure sensor problem?

A vehicle with an EVAP system issue can be driven, but may get lower fuel mileage and run roughly. Also, a vehicle with an EVAP system issue won't pass standardized state or federal emission testing. 

How often do fuel tank pressure sensors need to be replaced?

EVAP system issues happen at some point to almost every vehicle. While the fuel tank pressure sensor doesn't commonly go bad, it will tell you when you have a problem with parts that fail more often, such as the gas cap. The gas cap is the number one reason EVAP failures are recorded.
