Temperature Gauge Resistance Test
Remove instrument cluster. Using ohmmeter, check gauge resistance across appropriate terminals. See Figure. Ensure ignition switch is in OFF position and harness connector is unplugged from instrument cluster. See TEMPERATURE GAUGE RESISTANCE SPECIFICATIONS table. Replace gauge if not within specification. If gauge is within specification, repair open or short circuit in wiring harness.
