Saturns do not use a speedometer cable to control the gauges on the cluster. It uses the magnetic pickup located in the vehicle speed sensor, mounted in the back side of the transmission. The computer then sends signals to the dashboard to operate the gauges electronically
It usually means that there is something wrong with the fuel gauge itself. It's like when the speedometer is out, just get i checked by the car manufacturer
check if the back of the spedomoter is pluged in th the gauge if not plug in
To remove the speedometer from a Toyota FJ40, first, ensure the vehicle is off and the key is removed. Carefully pry off the speedometer gauge's bezel using a trim tool to avoid damage. Once exposed, disconnect the speedometer cable by unscrewing it from the back of the gauge. Finally, remove any screws or clips securing the speedometer to the dashboard to complete the removal.
Gauges that fluctuate back and forth could indicate a problem with the sensor or the gauge itself. It could be caused by a faulty connection, a malfunctioning sensor, or an electrical issue. It is important to have it checked by a mechanic to diagnose and fix the underlying problem.
change the little box on the back of the gauge cluster should be white
Disconnect speedometer cable from back of speedometer gauge by twisting the threaded collar to unscrew. Then just slide the old cable out of cable housing and insert new one. If cable is broken you may need to disconnect cable from transmission tail shaft to remove part of the cable. Cable must be inserted into the gauge end of the cable housing.
There are light bulbs in the back of the gauges they can burn out
Unplug the coolant temp sensor and check what the gauge says...If it falls to cold, then the sensor is at fault. If it stays, then the gauge is either faulty or the contact points on the back of the gauges need to be cleaned...

with a full tank of gas the gauge will drop to "E" then after a few seconds it will jump back to correct reading.
There is a voltage regulator 4 the guages in back of the dash.there is another name 4 it but I'm not sure of it.One of your Parts experts will know the name of it :->AnswerI have a 1990 Astro, the coolant gauge and speedometer lights stopped working, i took it apart and noticed the bad design of the electrical harness. This plugs into the back of the dash and disconnects or shorts somehow. I'm thinking from gravity and vibration. It wasnt obvious it was loose, I plugged it back in and it worked for a couple of hundred miles, then not. Meanwhile I used a flashlight for the speedometer. My van overheated on the freeway and I would have known sooner had my gauge worked.My fault, their bad design.
