What happens when the fuel tank pressure sensor goes bad?
Over time a faulty fuel tank pressure sensor will cause low fuel efficiency, trouble starting the vehicle and/or stalling, and eventually keep the vehicle from starting.
Where is the EVAP fuel tank pressure sensor?
Unfortunately, the fuel tank pressure sensor is located inside your fuel tank or on top of the fuel tank near the hanger assembly that holds the fuel pump in the fuel tank itself.
Can I drive my car with a bad fuel pressure sensor?
Engine stalling might occur as the fuel rail pressure sensor goes from bad to worse. You will be driving and then suddenly, your engine will stall. This will make driving extremely difficult (and dangerous) and it should motivate you to do something about it.
Can you bypass a fuel tank pressure sensor?
You can plug and bypass the pressure sensor, but you will definitely have a check engine light on after the repair. The pressure sensor is there to determine that the fuel tank isn’t releasing fuel vapors in turn poluting the atmosphere (whoopdy doo.) You will be okay without it.
How much does it cost to replace a fuel pressure sensor?
Over time, this sensor may start to malfunction, and we’re going to tell you what to expect from a replacement service. This pressure sensor can cost you anywhere from $260-$320 to change out. The labor should be between $200 and $250, while parts will only cost about $70.
How long does it take to change a fuel tank pressure sensor?
Depending on the vehicle, it may only take a few minutes to replace the sensor but there is typically a one hour minimum. If you have some mechanical experience, replacing the fuel rail pressure sensor is a good DIY candidate.
Where is the pressure sensor on a fuel tank?
Placed atop or inside of your fuel tank is a component called the fuel tank pressure sensor. Let’s take a look at what your fuel tank pressure sensor is and what it does, signs that it has gone bad, and how to fix it. What is a fuel tank pressure sensor?

If you don’t have an automotive scanner you’ll have to lower the tank and pull the connector off the pressure sensor and test it with a voltmeter. If the voltage reading is either zero or five then it’s possible that you have a wiring problem.
