DTC P0452 Fuel Tank Pressure Sensor Circuit Low Voltage The fuel tank pressure sensor is located on top of the fuel tank. Circuit Description The fuel tank pressure sensor measures the pressure (or vacuum) in the fuel tank. The powertrain control module (PCM) provides the sensor with a reference voltage, a signal circuit, and a ground. The sensor returns a signal voltage to the PCM relative to the pressure in the fuel tank. The PCM should see a signal voltage increase as the pressure in the tank decreases (more vacuum). As the pressure in the tank increases (less vacuum), the PCM should see a signal voltage decrease. The PCM uses the sensor signal to test the integrity of the EVAP system. If the PCM detects a signal voltage that is too low, DTC P0452 will set. Your best bet , take your vehicle to a qualified repair shop.

Fuel Air Sensor at the exhaust manifold and Catalytic converter and the O2 Sensor after that Cat.

You have a plugged condensate line. Crawl under the dash and look for a rubber tube coming out of the heater box and going thru the floor. Lay old towels under the area and pull the hose off. You'll get a flood of water. Then use a pipe cleaner and water to clear the drain hose and flush. Reinstall and you should be good to go.

Check all of your fuses. You probably blew the accessory fuse.

Hi Jason Not much info to go on from your question. The simplest way to disconnect a Car Battery is by using a special battery terminal switch. This is a brass bar that attaches directly to the battery terminal and all the connecting wires go on the other end. The Knob on the middle is turned to isolate the battery. Hope this Helps. http://www.ebay.com.au/itm/141964353616?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT http://www.ebay.com.au/itm/Auto-Car-Motorcycle-Cut-Off-Switch-Side-Post-Battery-Master-Disconnect-Isolator-/391121153851?hash=item5b10a32f3b:g:iSMAAOSwLVZVtfhG

Check battery voltage should be around 13 volts if not charge it.

The security, antitheft or lock picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well. http://www.diy-gm-security.com/ g" alt="26123942-n0ruldykmagyusv0wgntwhg0-2-0.jpg">

Heater or mode door actuator bad , possibly ! You can look on youtube for videos showing how to change . It can be easy or very hard to replace . You could have it checked for DTC's diagnostic trouble codes stored in the heater control head . dealer only !

Check to see if you have not turned that feature off - normal feature. If not, then the door switches are bogus.

They are sometimes located in the glove box on the left side or in a console. I’m happy to help further over the phone at https://www.6ya.com/expert/david_66a56a0239b6ab32

How do I replace a power window motor on my 2000 Cadillac ? https://www.youtube.com/watch?v=S2qsjXrzmgA Hope this helps. Deville window regulator

Pull up the carpet and pad in the trunk to see if there is an access cover. If not then you'll have to drop the tank.

Do basic troubleshooting. Spark at plugs? Fuel pressure correct?

Hey Phill, I did find a good online diagrams at autozone library, (its all free,) just log in and list your car and go to repair help, its the same as I have 2000,there is a lot to it but AZ gives you all the details, I hope this helps you ,if it does please let me know by checking box below (helpful). thanks Woody

when you lean it forward to lift it up bring it up as high as it will go then give it a hard forcefull hit upwards ,that should work it worked on my 99.eldo

under the dash on driver side

if you have the north star motor it on drivers side tward front grill, you will find a belt cover you need to remove an you'll need a special tool most auto parts stores will rent it to you for a small fee ,it likes a large socket ,if you have the new one you'll see how it fits in socket, using a rachet with socket place over water pump and turn a 1/2 turn to left and it's out ,replace in reverse ,take care not to disturb new o ring seal ,and don't use silicone to seal it , BUT general motors strongly suggest you do use some type of motor sealant , now for the bad news =these motors are very bad with over heating issues that have plaged the north star for years , if you drain antifreeze make sure you use air purge valves to remove any air from motor (purge valve looks like a brake bleeder screw ) or it will continue to over heat, im guessing that's why your doing this , if over heating is a problem take the time to go over all aspects of the cooling system =belts, flushing motor, cooling fans working correctly ,coolant filled, well I REALLhope this helps you ,good luck with it . Woody

follow the upper radiator hose to motor next to waterpump ,im guessing you have the north star motor.

Google your codes & read up Stop using it before you ruin the exhaust converter & have it fixed
