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.
How can you tell if your fuel pressure sensor is bad?
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.
How does the PCM work with the fuel pressure sensor?
With the information that the PCM receives from the fuel pressure sensor, it will know the exact amount of fuel to give the engine. That way, the engine doesn’t receive too much or too little fuel. Instead, it receives just enough fuel to operate properly while lowering evaporative emissions.

What to do if your fuel tank pressure sensor is not working?
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.
Can a sensor be replaced with a trouble code?
Remember that most trouble codes refer to a specific circuit and replacing the sensor without confirming it is bad, may not solve the problem.
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.
What happens if your fuel tank pressure sensor is bad?
If the sensor itself is bad, there’s really only one thing that will happen. The check engine light will come on. Anytime this light comes on, you should get it checked out; a faulty sensor might not be so bad, but there are many other, more serious things that can trigger this light. It’s best to be safe.
What happens when a no code sensor failure is detected?
As for engine performance, a type “A” or one-trip failure, such as a severe ignition misfire, will immediately turn the malfunction indicator light (MIL) on and store a P0300-series trouble code. On the other hand, a type “B” two-trip code or pending trouble code won’t turn on the MIL until a second trip confirms a sensor failure.
Can a check engine light code be troublesome?
Oxygen Sensors, otherwise referred to as O2 Sensors, and their related check engine light codes, can be troublesome at the very best! Today we discuss the design and function of these sensors, and some of the pitfalls encountered during the diagnosis of their related fault codes.
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 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.
Why does my pressure sensor keep setting p0452?
Although the pressure sensor is often the cause of a P0452 or P0453 there are other possible causes. Breaks in the signal wire or the ground connection will also cause these two codes to set. So lets talk about verifying if this part needs replacing.

How does the fuel tank pressure sensor work?
An excessively low voltage from the sensor is sent to Engine Control Module (ECM). The fuel tank pressure sensor responds to changes in fuel tank pressure. Vacuum is consider negative pressure.
What is the SAE code for fuel level sensor?
Note: Although code P0463 is a generic code specified by the Society of Automotive Engineers (SAE), the code’s definition may be different depending on the vehicle manufacturer. Also referred to as a sending unit, the fuel level sensor is mounted in the fuel tank.
Where is the p051 code on a fuel tank?
How to Fix the P051 Code The EVAP Pressure Sensor, also known as a Fuel Tank Pressure (FTP) Sensor is a device that measures air pressure or vacuum in the evaporative emission (EVAP) system. This sensor is typically found on top of or inside of the fuel tank. Fuel vapors are stored inside the EVAP canister.
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.
This sensor is usually located near the middle of the fuel rail and is linked to the engine control unit (ECU), which is the central computer of a vehicle. It shouldn’t be confused with the fuel tank pressure sensor which is located inside or on top of the fuel tank. So what happens when the fuel rail pressure sensor goes bad and how will you know?
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? As its name suggests, this part is a pressure sensor for your fuel tank.
What are the symptoms of a bad fuel tank sensor?
If your fuel system does have a pressure problem, you’ll see these signs: Your check engine warning light comes on. Your fuel consumption increases noticeably. A loss of power and acceleration. Hard starting.
What happens when your fuel rail pressure sensor goes bad?
When your fuel rail pressure sensor goes bad, the “Check Engine” warning light may illuminate on your dashboard. This light activates whenever the engine control unit detects an issue within the vehicle that affects the engine in some way.
What kind of pressure sensor does a diesel engine use?
A fuel rail pressure sensor (commonly known as a fuel pressure sensor) is used in many diesel and some gasoline engines.
