Elgin Black Posted April 27, 2018 Report Share Posted April 27, 2018 Has anyone seen the code P2068 on a check engine light? Mine through the code yesterday. Looked it up and it has to do with the fuel gauge. I filled the tank and the gauge still shows 1/2 full. Quote Link to comment Share on other sites More sharing options...

GM vehicles do things like this if you do ??? Quote Link to comment Share on other sites More sharing options...
Elgin Black Posted April 28, 2018 Author Report Share Posted April 28, 2018 The engine was not running and the key was off. At first the Check Engine light would come on when the gauge hit 1/2 full. I was able to clear the code , but it round come back. Now the highest it will read is half a tank. Sounds like the tank will have to be dropped and the sensor and or the fuel pump replaced. I’m hearing it is a unit. Quote Link to comment Share on other sites More sharing options...
