How to remove pressure sensor from fuel tank?
Disconnect the fuel vapor tube assembly-to-Evaporative Emission (EVAP) canister quick connect coupling. For additional information, refer to Section 310-00. Disconnect the fuel vapor tube assembly-to-fuel tank quick connect coupling. For additional information, refer to Section 310-00.
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.
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 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.
Where is the fuel tank pressure sensor located?
The fuel tank pressure sensor is located on top of the fuel tank assembly. There should be an access plate located in the rear of the vehicle under the carpeting. Remove and you should be able to see the top of fuel tank assembly. The sensor has a hose and an electrical connector and a nut that you remove to pull out the sensor. Hope this helps.
Can a bad fuel tank pressure sensor be repaired?
Your fuel tank pressure sensor cannot be repaired if it has gone bad. It must be replaced. Given the dangers of working with automotive electronics and fuel systems, it’s best for most people to leave this job to a professional repair shop.
What should the voltage be on the fuel tank sensor?
When the air pressure in the fuel tank is equal to the outside air pressure, such as when the fuel fill cap is removed, the output voltage of the sensor will measure 1.3 to 1.7 volts. When the air pressure in the tank is 4.5 inches H2O (1.25 kPa), the sensor output voltage should measure 0.5 + 0.2 volts.
How much does a fuel tank sensor replacement cost?
Know what price you should pay to get your vehicle fixed. The average cost for a fuel tank pressure sensor replacement is between $399 and $480. Labor costs are estimated between $305 and $386 while parts are priced at $94. Estimate does not include taxes and fees.

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.
When do I change the voltage on the pressure sensor?
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. 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.
How much does it cost to replace a fuel rail sensor?
We recommend Parts Geek or Advance Auto Parts for the best prices and selection. The cost of replacing a fuel rail pressure sensor depends on the make and model of your vehicle. However, on average, you can expect to pay anywhere from $130 to $210 for a replacement job like this.
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 much does it cost to replace a fuel pump sensor?
The parts, on average, can cost $80 to $400, while labor, seeing it’s a relatively quick repair, can cost $80 to $250. In most cases, a technician will want to replace the fuel pump as this part often needs to be removed in order to replace the level sensor. At AutoZone, for instance, the top-selling fuel level sensors retail for $80 to $350.
What happens if fuel pressure sensor is faulty?
Not only that, if the fuel pressure sensor is faulty, it may output too little information to the ECU, which in turn may increase the amount of fuel being fed into the engine. As a result, you lose fuel and have to fill your car’s tank more frequently.
How much pressure in the fuel tank?
Fuel tanks are normally pressurized to approximately 3 pounds per square inch. If breather fitting (located on intake manifold) is restricted, there is potential for full turboboost pressure to reach fuel tanks when under load.
Where is th fuel tank pressure sensor located?
The Fuel Tank Pressure Sensor is located at the top of the fuel tank, mounted to the top of the fuel pump assembly. There is an “access door” inside the trunk. Remove the rear compartment floor trim.
