2005 envoy gas gauge is always on empty even when i fill up


Common problem is for the tiny stepper motor to go out in the back of the guage. Can buy off of E-bay, very cheap.

2006 ENVOY fuel guage reads empty after fill up. What is the cause and how to rectify?


Usually I find there are two common causes for this problem. If the gauge goes to empty after a fill up but then starts to work and be fairly accurate as the fuel level in the tank drops then it's often the fuel level sending unit which is attached to the fuel pump module inside the tank. I have seen some guages go bad also [actually the servo motor that runs the gauge] but usually the gauge will stick in one spot and rarely move or go to either end of the scale and stick there. A good shop should be able to determine the cause of your problem pretty quickly. Hope this helps and good luck!

My gas gauge goes to empty and miles until empty shows "---". This only last a few minutes and returns to normal.


The fuel level sensor is bad and will need to be replaced. The tank will have to come down to replace the sender.

2007 GMC Envoy - Gas gauge showing empty and check engine light


This is a safety feature that the vehicle brings. You need to reset the E.C.U on dealership or it will keep doing it to you. It was probably caused by one single time that you did not closed the fuel cap correctly. Good luck

My gas gauge was working fine...went to fill it up and it goes to completely empty to 1/4 tank to full then back to empty. What do I do?


you are going to need to get the gas gage sending unit replaced to fix this problem, the sending unit is located inside the fuel tank.

Gas guage-oxygen sensor?


The oxygen sensor has nothing to do with the fuel gauge. There are two possibilities for the gas gauge error, first it could be the in-tank gas level sensor or it could be a defective stepper motor which drives the gauge. A professional scan tool can determine the fuel level being sent by the in-tank sensor, if that disagrees with the gauge, then the stepper motor needs replacing.

Fuel gauge problems


Remove the sender wire from the fuel tank and short it to ground (metal part of tank).

If the fuel gauge goes to full then your sender unit is faulty and replace it.If not ,please come back to me .

Please leave positive feedback if you feel I have helped you.

Thank you

2006 GMC Envoy XL gas gauge reads empty after filling, then slowly moves up after driving but will continue to lose pressure until it reads empty and the light is on, then the check engine light came...


Sending unit. Its all one unit including fuel pump, float, ect. The check engine light is because of the high or low resistance in the unit. Let me know if you have already fixed.. You have to drop the tank to get to it also.
