The fuel guage of my crv 2010 is not working
i went to the mechanic to change the sparks
they connected the to their firmware
the connecting plug has 3 wires and now 1 of them is not connected and i dont know if that is the cause of the fuel gauge not responding to fuel levels.
I don't know, but if that is the OBD-II connector, there should be no wires attached to the front of it. The fuel gauge in the dash is all part of the whole instrument panel assembly attached by a common harness. Not unless there is some sort of aftermarket thing installed in the CR-V, in which case, sticking wires into the OBD-II connector is a very sloppy way of installing something.
