Command Link issues

[wlewis11]

On my CL (Plus, I believe), the large rectangular one, my fuel and trim bar graphs don't work. The fuel flow and fuel used readouts work fine and are accurate. I assume my in-tank fuel sender is bad. Am I correct? As for the trim bar graph, I recalibrated it by setting it at 0% when motor (F250) was all the way down. Is there a trim sender that might be bad? If so, where is it located?

The trim sender often gets stuck in the down position, and needs to be worked by hand to get it freed up, with some WD-40 type of stuff. Followed by periodic repeated attention.

So that might be your problem there.
Raise the motor all the way up, squat down behind it and look on the insides of the mounting bracket

Thanks for the info!

just because the arm moves does not mean the sender moved.
pay close attention to the screw.
if the screw moves with the arm it should work.
if the arm moves and the screw does not the sender is toast.

Rodbolt17, you are correct. Trim Sender arm was stuck in down position. I worked it and lubed it and seems to be working now, although bar graph display even though fully illuminated, blinks and is orange rather than the usual blue. Even though apparently independent of fuel tank sender, I wonder that a will change after replacing tank sender? Speaking of fuel tank sender, local dealer told me how to test it, and yes it is bad.
