2002 Pontiac Grand Prix - Answered Questions & Fixed issues

You can't do that. Without power steering you won't be able to turn the steering wheel. In the old days, it used to be power 'assisted' steering, but now the steering pump does all the work. You would fail at turning the first corner.??Get a friend to drive you to the junk yard.??..

Help here. It is a job best left to a specialist. https://www.google.com/search?q=2002+Pontiac+Grand+Prix+shift+solenoid+location ..

First replace the light switch. It controls all the lights you said don't work. The key chime is a small white switch on top of the ignition You have to remove the steering column bezel to get to it. They stick.

You should have the computer scanned at a transmission shop or a dealership. If you get a code P1811, that is the 'max adapt long shift' code. That means that the Electronic Pressure Control solenoid may be going bad. Normal wear and tear on the clutch material can also cause this code. Basically, it means that the transaxle is taking longer than 0.65 seconds to shift, and the computer commands maximum line pressure to avoid burning out the clutches. I have had good success with installing a shift kit on several of these transaxles (4T65e) to remedy this problem with no further issues. Visit www.transgo.com and look for distributors in your area. The shift kit you need is the SK 4T65e shift kit. The kit comes with very good instructions. It is not a difficult job. If you can drop the pan and change your own fluid, you can install this kit.

try googling for the diagram

a problem axle will vibrate worse the faster you go but the vibration will be there up or down so for the moment I will set that aside. if it is vibrating during acceleration but stops when the accelerator is released, it indicates and engine /transmission management problem first I would run the fault codes as the problem could be from a faulty cam position sensor servo/solenoid that has the cam too far advanced for the engine rpms and power setting next it could be a problem with injector control or fuel flow/ pressure have the fuel pressure tested at rpms to ensure that the pressure regulator is operational what you describe occurs from misfiring or the like so go to an accredited service center for a proper diagnosis and quote back to the axle --it could be a problem wheel bearing failing or needing adjustment so keep that in the back of your mind if nothing shows up in the fault codes or diagnosis from a shop with experience

The valves on the 3800 series 2 engine are not adjustable.

Easy way to tell if it is the key, is the security light on? If so, you should be able to leave the key in the ON position for 15 minutes or so and get the car to relearn the key. If not, I suggest making sure that there is sufficient fuel pressure at the fuel rail and make sure that the fuel injectors are metering.

I think they are M14 x 2.0 x 49 mm thread for the bracket mounting bolt.

You will need to either disconnect the battery for about a minute or reset with a scan tool or code reader.

OBD port connector ? Under the steering column area left or right of the column .

My personal suggestion would be to go for these repair catalogs from www.reliable-store.com instead. much better info on all vehicles, complete details, and they also have live assistance feature

Bad ignition switch

Sounds like a wheel bearing and or the brake pads are totally gone which is most likely. Change the pads.

Is the security light lit on the instrument cluster ? Anti-theft system problem ? DTC P0131 Heated oxygen sensors (HO2S) are used for fuel control and post catalyst monitoring. Each HO2S compares the oxygen content of the surrounding air with the oxygen content of the exhaust stream. When the vehicle is first started the powertrain control module (PCM) operates in an Open Loop mode, ignoring the HO2S signal voltage when calculating the air-to-fuel ratio. The PCM supplies the HO2S with a reference, or bias, voltage of about 450 mV. The HO2S generates a voltage within a range of 0- 1,000 mV that fluctuates above and below bias voltage once in Closed Loop. A high HO2S voltage output indicates a rich fuel mixture. A low HO2S voltage output indicates a lean mixture. Heating elements inside the HO2S minimize the time required for the sensors to reach operating temperature, and to provide an accurate voltage signal. This DTC will set if the HO2S 1 voltage remains below a calibrated amount for an excessive amount of time. Each HO2S 1 has the following circuits: • HO2S 1 high signal • HO2S 1 low reference • HO2S 1 heater ignition voltage • HO2S 1 heater low control • Low reference loop

Check spark, check fuel delivery to engine. Check OBD2 fault codes.

You need to replace the radiator thermostat and water temperature sensor and flash out old coolant.

You probably have a problem with one or both of the front brakes - probably a wheel bearing shot and ABS sensor failed or disconnected. I would take to a brake shop immediately, and not attempt a long run with the car.

Fuel pump.

could be the mechanism is jammed up i would advise you go to a local mechanic and have it looked at .
