What are the Signs of a Bad Fuel Tank Pressure Sensor? The fuel tank pressure sensor is a small device that monitors and regulates the air pressure inside your fuel tank. It’s located on the side of the gas tank, right next to the filler neck and under a plastic cover. This sensor can fail without any warning signs but often there’s at least one symptom before it stops working completely, which is why it’s important to keep an eye out for these red flags:
One of the most common versions of this part is the gas tank pressure sensor.
- One of the most common versions of this part is the gas tank pressure sensor. The fuel vapor canister, purge valve, and charcoal canister all use them as well. These components are used to monitor and regulate the car’s fuel tank pressure. If they’re not functioning properly, you may experience some problems with your vehicle’s performance.
Some other names for this component include fuel vapor canister, purge valve, and charcoal canister.
You may also see this component listed as a fuel vapor canister, purge valve or charcoal canister. The function of these components is similar and they are all part of your fuel system.
If a problem with any one of these components occurs, it could cause your Check Engine Light to come on and you should have your vehicle inspected by a professional technician order to determine the cause and repair options for your car’s check engine light problem.
The fuel tank pressure sensor monitors and regulates the air pressure inside your fuel tank.
The fuel tank pressure sensor monitors and regulates the air pressure inside your fuel tank. It also connects to an electronic control unit (ECU) that monitors the fuel tank pressure. The ECU controls several other components of your vehicle, including:
- The engine’s timing
- The engine’s ignition system
The ECU uses data from the sensors in your car to keep track of everything going on with it. In addition to monitoring the air pressure inside your fuel tank, this sensor also measures how many times your car has been started since its last oil change, among other things.
Because a small amount of air is allowed to escape from the fuel tank all the time, you will notice a decrease in mileage over time.

Signs that your fuel tank pressure sensor may be going bad include gas smell or smell of unburnt fuel from your exhaust pipe, poor engine performance and poor handling while turning or changing speed.
The following are signs that your fuel tank pressure sensor may be going bad:
- Gas smell or smell of unburnt fuel from your exhaust pipe.
- Poor engine performance.
- Poor handling while turning or changing speed.
A vehicle’s gas tank is constantly under pressure, especially when warmed up and driven around.
The fuel tank pressure sensor on your vehicle is responsible for monitoring and regulating air pressure inside your gas tank. It does this by allowing air to escape from the tank through a vent port when it has reached an appropriate level of pressure. When you turn on the ignition, power is sent to the fuel pump, which pressurizes fuel from its storage tank into the car’s engine through its own hoses and lines. If there is too much or too little air in the system at any given time, it can cause serious problems with performance and efficiency.
This is because air needs to be able to escape every so often because more air needs to be allowed in to take its place.
- This is because air needs to be able to escape every so often because more air needs to be allowed in to take its place.
- If you are noticing a decrease in fuel efficiency and your vehicle takes longer than normal for it’s “check engine” light to come on, this could be an indication of a bad fuel tank pressure sensor.
This constant fluctuation of air pressure means that there needs to be something monitoring and regulating it at all times.
The fuel tank pressure sensor is a part that monitors and regulates the air pressure inside your fuel tank, making sure it stays within a certain range. This constant fluctuation of air pressure means that there needs to be something monitoring and regulating it at all times.
When you put gas into your car, some goes down into the engine and some goes up into the fuel tank where it sits until you need it again. The fuel pump pushes this gas up through pipes until all of it has been used by your engine or spilled onto the ground, leaving only water vapor behind in its place (that’s why steam comes out of tailpipes).
Keep on top of your fuel tank pressure sensor by knowing what signs to watch out for so you don’t end up stranded with an empty gas tank.
If you’re concerned that the fuel tank pressure sensor may be going bad, there are a few signs to look out for. The first is a gas smell or smell of unburnt fuel from your exhaust pipe. This can indicate a faulty fuel pump, which is powered by the engine’s crankshaft and sends gas to the engine’s cylinders. A faulty fuel pump can also cause poor engine performance and poor handling when turning or changing speed.
Additionally, fuel tank pressure sensors are small devices that monitor the contents of your fuel tank. If these sensors fail, they can cause a number of problems ranging from excessive fuel consumption to the Check Engine Light. In this article, we’ll explore how a bad fuel tank pressure sensor works, how it affects your vehicle’s performance and what you can do if you suspect yours is failing.
Check Engine Light
One of the first signs of a bad fuel tank pressure sensor is that your check engine light will come on. The check engine light may be accompanied by other warnings, such as a low fuel warning light or red brake lights. The check engine light may go off again after a while, but if it comes back on often, you should visit a mechanic to have it checked out further. Read Also: Best Way to Check Brake Fluid
Vehicle Hesitates or Sputters
- Vehicle hesitates or sputters.
- Vehicle may not accelerate.
- Vehicle may stall.
- Idle speed is too high or too low.
Gas Smell in the Cabin
There are a few signs a fuel tank pressure sensor is bad. One of them is gas smell in the cabin. If you notice that your car smells like gasoline when it’s parked, no driving has occurred and all windows are rolled up, then there’s likely a problem with the fuel tank pressure sensor.
The odor may be more prominent when you’re driving because it leaks from engine compartment into the passenger compartment due to movement of other parts during operation.
Difficulty Starting the Engine
Difficulty starting the car is another sign that the fuel tank pressure sensor is bad. If the sensor is faulty, it may not be transmitting any information to your car’s computer. When this happens, your vehicle won’t learn how much fuel you have left in your tank and will assume there is less than there actually is. This will cause it not start properly or even at all when you need it most!
Excessive Fuel Consumption
- Running rich
Running lean
- Excessive Fuel Consumption
The fuel tank pressure sensor can fail over time.
The fuel tank pressure sensor is an important part of your car’s fuel system. It measures the amount of air in the tank and sends that data to your car’s computer, which uses it to calculate how much fuel you need to add when refueling. The sensor is also responsible for keeping tabs on how full your tank is. If you have a low-fuel light come on while driving, this means that either the sensor itself has failed or there is a problem with its wiring harness or connector.
If your car’s “check engine” light comes on due to an error code related to the fuel system, chances are good that it could be caused by a bad pressure sensor or other related component in this area — but don’t assume so! There are several other common culprits:
Conclusion
If your fuel tank pressure sensor starts to go bad, you might notice a decrease in mileage over time or an increase in gas smell. Pay attention to these signs so that you can get it checked out as soon as possible. The sooner that you do this work, the less likely it’ll be expensive or even impossible to fix! If you notice any of the symptoms listed above, contact a certified mechanic to inspect your vehicle and make sure it’s safe to drive.
