What I would do, if a Friday night and one not dedicated to getting myself too dirty for date night: Get my multimeter and some clip leads. Clip them to the connector in the little box to measure the sensor resistance. Use my foot to jostle the gray sheathed cable to the diff and maybe wiggle it from up above where it goes into the plate over the fuel tank sender.

If the trouble showed up, then I'd plan some down and dirty work with the wiring to the sensor.





If not, then I'd plan some sunny day work to find the pins in the long dual row plug and socket up near the driver's left toes where the harness joins. Might be wrong, but that's how I would plan it.

Progression of engineering education: a good planner needs to know at least a little bit about a great variety of topics, and engineers often succeed by specializing, so we planners like to say that over time, planners learn less and less about more and more until eventually they know nothing about everything. Engineers learn more and more about less and less until they eventually know everything about nothing.
