    It's worth a try. Turn the key to on, but don't start the engine for three minutes then turn the key off. Next, start the engine.

    Try this whenever the battery is totally disconnected or the electronic throttle is been flapped manually.

    For the windows, roll down the drivers window, then roll it up, when it hits the top keep holding the button for more than 3 seconds. You may have to do the passenger window as well. Good luck.

    There were some posts where guys recommended removing the CPS clean the face and reinstall. Is seems the metal particles from the engine collect on the face of the CPS causing it to not do its job. If the wait is long for the part, consider trying that. Good Luck.

    I have a link to where you can get them at..... Advanced Auto Parts has them, there about 80 bucks +/-. You can order them online if you can get them in the stores.....

    JGABRIELSON...thanks for the advice...im going to give the f1 &f6 thing a shot. as for the part, i already have it ordered and it should be here by wednesday... "so they say"

    SAMMYZ...i will try cleaning the CPS and reinstalling it, but do you think it tested bad at the dealership because it was dirty?

    Re: CTS problems...

    The theory was that the build-up on the face of the sensor was causing the problem so some guys thought just cleanining it may work, but others said, if you're going though the trouble of removing it, you might as well replace it. I don't think anyone ever tested the theory. If mine ever fails again, I'm going to try and clean it. Good luck with the codes, mine never sent a code.

    Re: CTS problems...

    well i have gotten my CPS in...and got the instructions for it...needless to say, this makes no sense whatsoever. i have found two different instructions on this, and i realize they are probably mislabeled and should be marked for different engine sizes. but has anybody changed out a CPS on a 3.2L engine? if so, could you please assist me in this project that seems to be kicking my A$$, and before i give in to the sorry ass dealership who is going to charge me another ungodly amount just to look at the car before they change out the small part and ad labor onto that amount...thanks for all the help

    Re: CTS problems...

    It's hard but not impossible to do it yourself. You will need a Torx socket, (not bit) and some string. The CPS is near the oil filter, under the car. Do a search on CPS for detail instructions and pictures. It takes about an hour. Don't bother trying to route the wire exactly like the original. I just zip tied mine away from the heat of the engine. The connector is in the back of the engine and you have to lay on the engine to get back there to see it. Pull the old wire through with the string attached so you can pull the wire through.

    thanks everybody for your advice on the problem and how to change it...
