Symptoms of a bad fuel tank pressure sensor; a bad fuel tank pressure sensor can cause a wide range of issues, including stalling, poor acceleration and hesitation. The fuel tank pressure sensor is responsible for measuring the amount of air in the gas tank so that it can determine when it needs to add more fuel. This article takes a look at some common symptoms that indicate your vehicle may have a bad fuel tank pressure sensor.
Engine Misfire or Hesitation
When your fuel tank pressure sensor is bad, it can cause an engine misfire. If you experience a hesitation in the engine or a car that stalls at low RPMs, this is likely a sign that your fuel tank pressure sensor needs to be checked.
Loss of Power and Acceleration
If you experience loss of power, acceleration and/or the check engine light stays on, it may be due to a bad fuel tank pressure sensor. A missing or faulty sensor will cause the computer to keep your car in “limp home mode”, which will result in decreased fuel economy and poor performance. If your vehicle is experiencing any of these symptoms, have it checked out by a professional mechanic as soon as possible. Related Article: What are the Signs of a Bad Fuel Tank Pressure Sensor?
Check Engine Light Stays On
If you experience the check engine light staying on, it can be a warning sign that your fuel tank pressure sensor is bad. This warning light will not always mean there is an issue with your car’s engine, but it is important to take note of it as it may indicate something more serious. The check engine light can come on for a variety of reasons including:
- Bad Gas Cap
- Worn Brake Pads
- Low Tire Pressure
- Bad Fuel Tank Pressure Sensor
Increased Fuel Consumption
If the fuel tank pressure sensor is bad, it can cause your vehicle to burn more fuel than normal. This is because if your car’s computer does not know how much fuel is left in the tank, it will make up for this by adding more gas as needed. This results in increased engine RPMs and increased gas consumption.
A bad fuel tank pressure sensor can cause a wide range of issues.
A bad fuel tank pressure sensor can cause a wide range of issues. It can lead to the check engine light being illuminated, which indicates that there is a problem with your vehicle. It also could result in engine misfire. This means that there is an issue with how well your engine ignites the air and fuel mixture when you start it up, which leads to an increase in fuel consumption and loss of power as well.
When this happens, it’s important to get your car checked out by a mechanic right away so they can diagnose what exactly is causing these problems and make sure they’re fixed before things get any worse!
In general, fuel tank pressure sensors are an important sensor in a vehicle. The use of this sensor ensures the vehicle’s fuel injection system that the pressure in the tank is constant and correct. Fuel tank pressure sensors fail over time and must be replaced to ensure your vehicle runs properly. Although a bad fuel tank pressure sensor may not affect how your vehicle drives, if left unaddressed, it could cause other problems.

In order to determine whether or not you have a faulty fuel tank pressure sensor, there are some simple tests you can perform on it yourself. You should check for voltage at its terminals when you start up your car and also after it has been running for a few minutes. If there is no voltage present at this point then chances are good that one or more of its components has failed internally due to oxidation buildups over time; however keep in mind that sometimes these components will actually work intermittently (i..e they will sometimes report normal readings while others show failure).
Here are some of the symptoms of a bad or failing fuel tank pressure sensor:
- Check engine light is on.
- Engine idle speed fluctuates.
- Fuel economy is not as good as it used to be.
- Vehicle hesitates while accelerating, especially when you come to a stop and try to accelerate again.
- Check Engine Light is on
The check engine light is the most common symptom of a bad fuel tank pressure sensor. If your car has this light on, don’t just ignore it. This warning light is there for a reason: if ignored, your car will soon be facing more serious issues that may require expensive repairs. The easiest way to turn off this warning light is by resetting the computer; but ideally you should make sure it’s turned off before driving again so that you can get checked out when you arrive at your destination (or before).
If this happens repeatedly and consistently every time you drive, there may be something wrong with other parts of your car—such as its wiring or battery—that are causing problems with how well they function together as one unit.
- Fluctuation of the Engine Idle Speed
- Fluctuation of the Engine Idle Speed
If your car’s engine idle speed is fluctuating, it may be due to a bad fuel tank pressure sensor. The fuel tank pressure sensor is responsible for ensuring that the engine is receiving sufficient fuel from the tank to keep running when it runs out of gas, which means that if this sensor isn’t working correctly and failing to provide enough fuel to keep your car alive at an acceptable speed, then you shouldn’t be surprised if your car starts slowing down while driving on long stretches of road or highway.
- Fuel Economy is not as Good as Before
If your fuel tank pressure sensor is failing, it can have a negative impact on the economy of your vehicle. If you notice that your car seems to be using more gas than usual—or if you’re simply not seeing the same level of economy that you did before—it may be worth checking out this component.
If the fuel tank pressure sensor is bad, replacing it should help to improve your mileage back up to where it was before.
- Vehicle Hesitates while Accelerating
If you’re having trouble accelerating, it could be because of a faulty fuel tank pressure sensor. This particular sensor is responsible for monitoring the amount of pressure in the fuel tank. If this sensor malfunctions, it can cause your vehicle to hesitate when accelerating and cause the check engine light to come on. You may also notice that your gas mileage has decreased and that your vehicle’s idle speed fluctuation is higher than usual.
A quick and inexpensive fix for a bad fuel tank pressure sensor is to replace it with a new one from your local auto parts store. If your check engine light comes on, get it checked out right away before you have more serious issues later on down the road
The check engine light can be a warning sign of a serious problem, but it can also indicate minor issues that are easily fixed. If you have not already done so, we recommend taking your car to a mechanic for diagnosis and repair.

You may also notice poor vehicle performance including decreased gas mileage and increased driving and idling time as well as hesitation when accelerating from slow speeds or turning corners at high speeds.
Conclusion
If you suspect that your fuel tank pressure sensor is bad, it’s a good idea to have it checked out by a professional. A skilled mechanic will be able to diagnose the problem quickly and accurately so you can get back on the road in no time at all.
