Can you drive with a bad fuel pressure sensor?

As the problem with your fuel rail pressure sensor gets worse, you’re going to begin to find that it will become more difficult to drive your car around due to the issue. Once you reach this point, you should not continue to drive your car around with a bad fuel rail pressure sensor in it.

Where is the fuel sensor located?

The fuel tank pressure sensor is part of the fuel pump assembly and is mounted on top of the tank or inside the tank. It’s 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.
