280 ω

According to the amount of fuel in the tank, the resistance should be somewhere between the specified values for "tank full" and "tank empty".

  • ‒ If the resistance is 0 ωor ∞ ω, this means there is a short circuit or an open circuit in the wiring in the tank.

Note:

In order to test the resistance for "tank full" and "tank empty", remove the sender -G and move the float all the way to its top or bottom position .
