#63 of 71 Fuel Gauge Issue by shopdog97 Sep 08, 2009 (11:00 am)
My son's 96 GV now has an issue with the fuel gauge. Sometime is doesn't register correctly when he fills up, and other times according to him, it takes it's good old time to get up to the full mark. He also said that the low fuel indicator chime will go off even when there is plenty of fuel in the tank. I'm inclined to believe that the trouble is with the sending unit in the tank, and not the gauge itself. How can I be sure? If anyone knows a test proceedure for this problem, I'd really appreciate it.Thanks!

Replying to: shopdog97 (Sep 08, 2009 11:00 am) My van did that with one tank full, but never before or after. I tend to agree with you without further verification though. I suspect the sending unit. I am not, however, sure of the testing procedure. There are three wires that go to the tank - one is the negative, one is the 12V, and the third, I imagine, is for the sending unit.

Replying to: xwesx (Sep 08, 2009 11:03 am) Thanks for the info, xwesx. A friend has a service manual for this van, and we'll look in there to see if there's a test proceedure for this issue. I'll be sure to check the wiring going into the tank to see if maybe there's a problem there. I'm not looking forward to having to drop the tank if it turns out to be the sending unit, and I may try and convince my son to just live with it since he and his family really don't travel that far. If there is ever an issue with the fuel pump, that would be the time to address the sending unit should the need arise. Thanks again!

Replying to: shopdog97 (Sep 12, 2009 3:49 pm) Back in the old days, the sending unit was a simple potentiometer (variable resistor) connected to a float. As the fuel level in the tank changed, so did the float position, and, since it was connected to the pot, so did the output voltage from the pot. The output voltage drove the fuel gauge directly.   I am not sure if today's vehicles use that same, simple concept or something more complex, maybe involving the ECU.   You son's symptoms could be explained by a float that was sticking.

Replying to: srs_49 (Sep 12, 2009 4:20 pm) The sending unit setup in my '98 DGC looked to be that exact setup. I replaced the fuel pump just a few weeks ago, and I certainly hope you do not need to drop the tank over a fuel gauge.... Replies to this message: srs_49 (Sep 13, 2009 1:36 pm)

Replying to: xwesx (Sep 12, 2009 9:38 pm) I've never had to replace the sending unit, but I think they're accessible from the outside - either under the vehicle or through an inspection port that you can get to by removing the rear seats (this being on a standard sedan).   Then again, you can have your son just ignore the gas gauge and just fill it up based on miles driven, say every 200 miles if you want to be conservative.
#70 of 71 96 grand voyager speedometer issue by aaronwatson Oct 09, 2009 (8:54 pm)
Hi, we recently purchased a 96 grand voyager in Michigan. It has done a lot of miles and we just drove it to vancouver. It has recently started to on occasion lose some power and the speedometer simultaniously. The speedo will flicker up and down or sit on 0 and it loses some power as well sometimes when this happens.   Any input would be greatly appreciated.

Replying to: aaronwatson (Oct 09, 2009 8:54 pm) It is mostly likely either a faulty speed sensor or a bad connection to the speed sensor.
