Hi guys,
98 TJ. My gas gauge sometimes gives low readings. Early on I had a general problem with the gauges and airbag light. I did the procedure recommended here of slightly bending all the contacts. It worked fine and the gauges never went dead again and the airbag light never comes on. I do continue to have an occasional problem with the gas gauge. It will either read a half tank when I'm full or empty when I'm below half. No amount of smacking the dash will clear it. I have driven forward and reverse doing 'brake checks' in an attempt to jostle the tank sender. Nothing like that clears it. However, simply turning the ignition key off and back on will almost always clear it up. I know about the gauge test trick, but its hard to catch it in a failed condition because turning the key on and off fixes it. Its almost like there is a relay or something electromechanical feeding that circuit that makes better contact after getting the key turned off and on. Can't see anything obvious in the wiring diagrams. Any ideas? Its not a big problem, maybe once a week it will act up. Thanks -Nick- posted
