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.

Where is the fuel tank pressure sensor located on a 2005 cts

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.

I'm trying to change the fuel pressure regulater valve on my 2004cts cadilac.I checked the fuel rail not there. Someone told me It is on top the gas tank.Please help me locate it.

What engine does yours have ? 3.6 L engine the regulator is inside the fuel tank !
2.6 an 3.2L is on the fuel rail !
5.7L inside fuel tank !
The fuel pressure regulator attaches to the fuel return pipe on the fuel sender assembly. The fuel pressure regulator is a diaphragm-operated relief valve. A software bias compensates the injector on-time because the fuel pressure regulator is not referenced to manifold vacuum. The injector pulse width varies with the signal from the mass air flow (MAF)/intake air temperature (IAT) sensor.
With the engine running at idle, the system fuel pressure at the pressure test connection should be between 380-410 kPa (55-60 psi). With the system pressurized and the pump OFF the pressure should stabilize and hold. If the pressure regulator supplies a fuel pressure which is too low or too high, a driveability condition will result.
You would have to change The modular fuel pump sender assembly !
Now what makes you think you need to have it changed ?

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

Why does my 2006 Cadillac CTS power engine down when I press the gas to pass other vehicles or try to excelerate?

Try shifting down to 2nd gear and see what it does. Put top grade full in it with extra cleaner. Check air intake filter and clean sensor. Has the fuel filter been changed ?
If this don't do it , check out the electric computer transmission set.

How do i replace fuel pump on a 2006 CTS Cadlly

You must remove the fuel tank from the vehicle to get to the fuel tank module. Your vehicle is equipped with two fuel tank modules that are connected by a tube inside the fuel tank. The primary module is the one on the left side and it is the one that contains the fuel pump.

Have you scanned your computer system to verify that there is not a problem with the security system or the fuel pump circuits? Did you actually check for fuel pressure at the fuel rail? I'm only asking because dropping a fuel tank and replacing a fuel tank module is not easy or cheap....A BIG investment if you are not absolutely certain that this will fix your problem.

CTS check engine light code P0451

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.
