my speedometer and oil pressure gauge not working any ideas what might cause this?
my oil pressure gauge stopped working and my speedometer works sometimes.changed oil sending unit .when i remove battery cable (hot) to reset everything speedometer works for a little while maybe a day or two then messes up again but the oil pressure gauge still shows maximum pressure reading.
Check the fuses to the instrument panel. Probably a 15amp.
check electrical speedometer wiring for a short circuit, check your vehicle speed sensor, check your ECM..
