Is there a problem with the fuel tank pressure sensor?
Sidebar: The diagnostic steps above cover the most common problems. However, in rare cases you could have a real fuel tank pressure problem. A malfunctioning vent valve or a defective pump that supplies the pressure to the tank for the test can also fail.
What is the Check Engine Light code on a gas tank pressure sensor?
This fuel tank pressure sensor article covers a boatload of General Motors cars and trucks. These automobiles will set a check engine light code in the P0440 range. However, when the sensor itself causes a problem, P0452 or a P0453 set for the fuel tank pressure reads low or high respectively.
What should fuel pressure be on 2002 Vortec 6000 6.0L?
I have also checked my fuel pump voltage and was wondering if anyone knows the proper voltage for a one plug fuel pump for a 2002 2500hd 6.0L? Key on/engine off the fuel pressure should be 55-62 psi. Try the key off and on several times to see if it goes up. After the pump stops (key still on) the fuel pressure may vary, then stabilize.
What should the voltage be on a fuel tank sensor?
The voltage should never read zero or 5 V. Instead the reading should be somewhere in between those high and low points. The voltage should also change when the engine is first started. If you do find a fixed voltage reading between zero and 5 V you most likely have a defective sensor.
What should the fuel pressure be on a Chevy Silverado?
If you want to save some bucks on this purchase take a look at my recommendations here: Where To Buy A Fuel Pressure Test Gauge. FUEL PRESSURE SPECIFICATION: The fuel pressure specification for the 1999-2006 4.8L, 5.3L, 6.0L Chevrolet Silverado (Suburban, Tahoe) and GMC Sierra (Yukon, Yukon XL) is 55 to 62 PSI. Flex fuel engines: 48-54 PSI.
Is the MAP sensor on a Chevy Silverado?
The MAP sensor, on the 1999-2006 V8 Chevrolet Silverado (Suburban, Tahoe) and GMC Sierra (Yukon, Yukon XL), is not an expensive engine management component. The following links will help you to comparison shop and hopefully save you a few bucks on its purchase (AC-Delco is the original equipment manufacturer):
Is the fuel tank pressure sensor a 5 volt sensor?
Here are the facts about the fuel tank pressure sensor: 1) The fuel tank pressure sensor is a 0 to 5 volt sensor. 2) You should NOT see a stuck on 0 or 5 volt signal value, using a scanner or volt meter. It has to be somewhere in between. 3) If sensor’s stuck at 0 volts, then the 5 volt wire is broken.

What do I do if my gas gauge is not working?
In most cases, to gain access to the fuel tank sending unit mount / fuel pump mounting hole, you’ll need to drop the gas tank down. Be sure to do this when there is either minimal gas in the vehicle, or it’s been siphoned out.
What happens if you put in gas tank to ruin engine?
The vehicle will run at first but will halt altogether when there will be no trace of fuel in the tank. If you leave it too long inside the fuel system, it will corrode and cause rust to several engine components because it contains chlorine – a highly corrosive oxidizer. What Happens If You Fill Up a Car with Bleach? – YouTube
What does a pressure sensor on a fuel tank do?
As you can guess from the name, the fuel tank pressure sensor reads pressure in your fuel system. By doing this it helps you detect if you have any leaks, especially ones that are caused by evaporation. That’s why it’s part of the evaporative emission system.
In most cases, to gain access to the fuel tank sending unit mount / fuel pump mounting hole, you’ll need to drop the gas tank down. Be sure to do this when there is either minimal gas in the vehicle, or it’s been siphoned out.

Can a bad fuel pressure sensor cause a car to stall?
But even if it is the first time you stalled, it could still be due to a bad fuel pressure sensor. 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.
How long does it take to replace a fuel 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. Note: Do not confuse the fuel rail pressure sensor with the fuel tank pressure sensor.
Where is the fuel rail pressure sensor located?
If you have some mechanical experience, replacing the fuel rail pressure sensor is a good DIY candidate. Note: Do not confuse the fuel rail pressure sensor with the fuel tank pressure sensor. The later is located inside or next to the fuel tank and requires a lot more time to replace.
How to test and replace a fuel level sensor?
How to test and replace a fuel level sensor. Because it’s an in-tank fuel pump, the hardest job is removing the fuel pump from the vehicle. Doing this test can help you pinpoint why the fuel gauge is not working. If this sensor is indeed working on your vehicle, then check the fuel gauge itself. This specific vehicle is a 2010 Subaru Impreza.
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. Note: Do not confuse the fuel rail pressure sensor with the fuel tank pressure sensor.
Why is my fuel pressure sensor not working?
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.
What does a fuel rail pressure sensor do?
The fuel rail pressure sensor is responsible for analyzing the pressure of the fuel that is inside the rail of the fuel pump assembly. This sensor is an electronic device which calculates the fuel pressure and then sends this information to the PCM (powertrain control module). The PCM is the main computer of a vehicle.
