Engine Coolant Temperature Gauge Resistance

Turn ignition off. Remove instrument cluster. Using ohmmeter, check gauge resistance between appropriate terminals on back of instrument cluster. See ENGINE COOLANT TEMPERATURE GAUGE RESISTANCE table. See Fig 1-Fig 4 . If resistance is not as specified, replace temperature gauge. If resistance is as specified, repair open or short circuit in wiring harness.
