yes the pressure sensor in mounted in a rubber grommet on the top of the fuel tank. it could be the sensor but the only way to know for sure is have the dealer do a evaporative emissions fuel tank pressure test, they have the special tools to do this, outside shops do not. Have u tried a new gas cap, they can leak and cause the problem, in fact that is very common.

Hi. the fuel pressure sensor is part of the fuel pump assembly. You will have to remove the fuel pump to replace this. I would go ahead and replace the fuel pump while you are there.You will have to Pull the strainer off the fuel pump and discard it. remove the retaining clip for the fuel pressure regulator so that you can remove the fuel pressure regulator. Disconnect the electrical connections for the fuel pumps and the fuel level sensor. Remove the retaining clip for the fuel level sensor and remove the fuel level sensor by squeezing the locking tangs. the sensor is incorporated in this area.

Please rate and god bless.

fuel pump check valve doesn't cause pressure loss, just hard starting cold, the check valve is part of the fuel pump, so to replace the valve u must replace the pump. do not use anything but the orig style pump, here is the part number from THE OE PUMP MAKER AT www.rockauto.com
DELPHI Part # FE0071 PRICE $124.99

You have a problem in the fuel pump relay circuit for sure then. I'm betting the relay, but it could be that dropping resistor.

What does code PO453 mean


the evaporative emission system (EVAP) control system pressure sensor has sent high voltage to the ecm or engine control module and triggered this code either the purge valve located under the car by the gas tank has gone bad, or the charcoal canister has become gas soaked and is pressurizing from gas fumes, or the sensor or wires have shorted , there is also a secondary valve located und the cover of the intake that should also be checked for shorts that can trigger this code but usually it is the one under the car that goes out 9 out of 10 times it is from fuel being burped into the evap canister or charcoal canister from the gas tank which is caused from overfilling the tank or mid day heat of 90 or better with a full tank

P0452 means fuel tank pressure sensor circuit low pressure. Possible symptoms:
- Fuel Tank Pressure Sensor harness is open or shorted
- Fuel Tank Pressure Sensor circuit poor electrical connection
- Faulty Fuel Tank Pressure Sensor
The code 0305 means cylinder 5 misfire detected. Possible symptoms:
- Faulty spark plug 5
- Clogged or faulty fuel injector 5
- Faulty ignition coil 5
- Fuel injector 5 harness is open or shorted
- Fuel injector 5 circuit poor electrical connection
- Ignition coil 5 harness is open or shorted
- Ignition coil 5 circuit poor electrical connection

P0453 evap emission control system pressure PRVS sensor high


i would make sure that all the connections at the fuel tank pressure sensor are good also check for bent lines that may be restricting fuel , even the return line and vapor return line.
these trucks do have a lot of wiring problems for the fuel tank pump. check the ground for the pump, it goes to frame. if you need to add another ground wire and splice it in.

If the truck was running good before the tank drop then double check everything . also you may have a bad sensor. with your scan tool you could , if the scan tool can. test sensor by add air to tank,make sure to clip the vent line and check readings when adding air to tank and then release the air and watch the readings if they do not go up and down then replace the sensor.

Have 04 mercury grand marquis check engine light is on for code po452 had that fixed and light still on


Well ---PO 452 is still FTP Sensor Circuit Low Voltage Detected
new sensor or not



If the sensor reads less than .22volts with key on /engine off --you get a hard fault (code)


Check Sensor Connector


Sensor with no pressure or vacuum in tank is 2.4 to 2.8 volts
Key On/Eng Off On scan tool PIDS


You just need a shop with a data base & proper test procedure
or a different tech or different dealer.

Whats the possible causes of a P0452 code on a 2001 Chevrolet impala?


Here is the definition of the code.

P0452 CHEVROLET Description The fuel tank pressure sensor responds to changes in fuel tank pressure. Vacuum is consider negative pressure. The information supplied by the fuel tank pressure sensor to the Engine Control Module (ECM) is used in order to detect vacuum decay or an excessive vacuum during the EVAP diagnostic routine.


The fuel tank pressure sensor signal voltage to VCM varies from a minimum of about 0.1 volts with pressure in the fuel tnk to greater than 4.0 volts with high vacuum in fuel tank.

Your fuel level sensor is on the side of your fuel pump inside the gas tank. The pump will need to be removed and the sensor straightened out... Since excess fuel is pumped back into the tank from the fuel pressure regulator, (as well as emission return and vacuum) they probably messed something up there as well and gave you emission errors.

Unless is was the one doing the testing I can not say that it will fix the problem. I would check the fuel pressure, the fact you have a rich code (P0172) means you may have excessive fuel pressure and the sensor is reading that.I assume this is a four or six cylinder and you have only one bank of cylinders. Check the fuel pressure before you do any parts replacing.

Could be a wiring issue, fuel cap got left off, fuel pressure sensor again or loose connection to the sensor and one of the other Evap hoses. Also might try changing the fuel cap. Look at the underside of the fuel cap and if there are cracks in the sealing rubber, replace the cap.
