ECT Gauge Resistance Test
- Remove instrument cluster. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Disconnect instrument cluster harness connectors. Go to next step.
- Using an ohmmeter, check ECT gauge resistance across appropriate terminals. See ECT GAUGE RESISTANCE SPECIFICATIONS table. See Fig 1 . If resistance is not as specified, replace ECT gauge. If resistance is as specified, ECT gauge is operating properly at this time.
