On a Buick, it is located on top of the fuel tank. It is set into the module that contains the fuel pump assembly. If you have an access panel under the rear seat or inside the trunk area, whereby you can get to and change the fuel pump assembly, you should be able to remove the access panel and see the sensor where it sits in the fuel pump module or housing.

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.

SOURCE: I would like to know were the fuel tank pressure sensor

The sensor is located on top of the fuel pump. It should be black in color. You have an access plate in the trunk to get to the fuel pump without dropping the tank.

SOURCE: 2005 Lincoln Town Car suffering from low fuel

The ford spec listed in the ford engine control manual is:

General Specifications Item Specification Fuel tank capacity 71.9L (19 gal) Fuel Pressure Hot restart 448-482 kPa (65-70 psi) Key ON Engine OFF (KOEO) 140-415 kPa (20-60 psi) Key ON Engine Running (KOER) 170-280 kPa (25-40 psi)

Are you measuring the fuel pressure with a mechanical gauge or are you using a scan tool . If with a mechanical gauge, does the gauge have an air purge? What symptoms does the vehicle present. If running rough you could have a fuel injector leaking. Are you measuring the fuel pressure with the key on engine off? If so, did you cycle the key a few times? Good luck

How do i change a fuel tank pressure sensor on a cadillac cts 2006 3.6 L?


The pressure sensor is a part if the fuel pump assembley. If you drop the fuel tank you will see a small black box on the top of the fuel pump assy thats the pressure sensor. You should be able to just pop it out of the rubber gromet and install the new one. You may need the help of a flat blade screwdriver to pry it out.

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

Where is the location on oil pressure sensor on 05 cts 3.6


The sensor/sender is easily replaced. It is located on the horizontal surface of the "V" of the block at the rear of the intake manifold on the driver's side. R&R requires a deep-socket about 1 1/16" or so.

05 Cadillac will not start after spinning out on interstate.


there is an oil pressure switch that shuts the fuel off if the key is on and the engine has no pressure. the switch is useally located near the oil filter on the block, this is not a common problem so it is unlikely it is your cause of no fuel pressure.
