Thread: Fuel gauge nightmare

Damn, my 2000 GT does the same. I have a buddy who is a master tech and he said I could use his brand new bad ass cpu reader to find out where the problem is. When I find out, I will share my info with you all too.

The CPU reader will likely tell you you are getting codes to several sensors, but DO NOT start swapping sensors willy nilly, just because you see a code with its name in it. The sensor or sensors could be fine, and the problem could be something else associated with it, like a lack of voltage to it. THINK about WHY you are getting codes all of a sudden on several things. Is there a common root cause? Then get hold of and electrical diagram and trace things out, see whats common to the sensors in question. You may also by doing a google search on the sensor name, come up with how tos on checking the sensor itself with a multimeter either in or out of the car. If I just blindly replaced every sensor that threw a code on the problem I just went through, I would be out well over a hundred bucks (even more if a shop was doing the work, and they , unfortunately also tend be sensor swap happy), and still have my problem will all new sensors. The total material cost to fix my problem, because I checked the cheap stuff (wiring) first, ended up being less than a penny for several inches of black plastic electrical tape. I actually spent most of my time solving this problem by researching what the codes I was seeing meant, looking at the wiring diagram to see how they could be related, and thinking about what might be causing them all to be thrown together. Actual time between first popping the hood to fix things, and finding the source (the pinched wire on the TPS), after I did all the thinking part of the job, was less than ten minutes. I'm not saying all of these types of fixes are that easy, but THINKING rather than just REACTING to a badass CPU reader display is the way to go.
