Common Bad Fuel Pressure Sensor Symptoms
Source: | Author:pmo0bc605 | Published time: 2019-12-09 | 1556 Views | Share:

If there is something wrong with your fuel pressure sensor, then there are some easily recognizable symptoms that will become apparent to you. Below are the top 5 symptoms for you to watch out for in case the fuel pressure sensor of your vehicle goes bad.


1) Warning Light

If you see the engine warning light illuminate on your dashboard, then it could be a sign that your fuel pressure sensor is bad.

Sometimes the engine control unit will sense a problem with the signal from the fuel rail sensor. Then it will activate the check engine light to let you know there is some kind of problem that is related to the engine.

Of course, there are a plethora of other reasons for why the engine light would turn on besides having a bad fuel pressure sensor.


2) Low Power

If you step on the gas pedal and notice a decrease in your acceleration power, then it could be due to the fuel pressure sensor.

If the sensor is bad, then it will interfere with the air and fuel ratio. This will cause power to be lost from your car as you’re driving.

3) Start Trouble

If you try to start your vehicle’s engine and it consistently gives you problems, then your fuel pressure sensor is probably not sending a good signal to the engine’s computer.

At first, the engine will eventually start after a few tries. But then, it will get to a point when it doesn’t start at all.


4) Stalling

Sometimes you might get a surprise and have your vehicle stall as you’re driving it. If you previously had trouble starting your car but then got the engine to turn on, you may experience stalling as you’re driving later on.

But even if it is the first time you stalled, it could still be due to a bad fuel pressure sensor.


5) Bad Fuel Efficiency

With a bad fuel pressure sensor, the engine will not receive the proper amount of fuel for its internal combustion process. Because of this, the engine won’t release the right amount of energy for the rest of the car’s components to function properly.

To make matters worse, you could end up burning too much fuel and then have to pay more for fuel at the gas station.
