Here is an example of an impossible fuel gauge reading. The left side is stuck at seven and the right side is below 1.4 hovering between one and zero right now.
That means I have less than a gallon of gas come to find a gas station right away.
The reason this is impossible is that when working properly the right side tank will stay at 014 until the left tank goes to 000. My left tank sensor is dirty or bent or something it never reads below 7L. I noticed something was afoot when my DTE stopped dropping one day about 37 mile to empty; I drove about 20 miles and it never changed.
I'm not sure if i refurbished mine or wife's left side sender but it's not a difficult task so apparently i have a job to do.
