Temperature Gauge Resistance Test
Turn ignition switch to OFF position. Remove instrument cluster. Using ohmmeter, check gauge resistance between appropriate terminals on back of instrument cluster. See TEMPERATURE GAUGE RESISTANCE SPECIFICATIONS table. See Fig 1-Fig 6 . If resistance is not as specified, replace temperature gauge. If resistance is as specified, repair open or short circuit in wiring harness.
