Test H: Engine Coolant Temperature Gauge Inaccurate/Inoperative

  1. If instrument panel cluster diagnostic system check has been performed, go to next step. If instrument panel cluster diagnostic system check has not been performed, go to INSTRUMENT PANEL CLUSTER DIAGNOSTIC SYSTEM CHECK  under SELF-DIAGNOSTIC SYSTEM.
  2. Turn ignition switch to OFF position. Connect scan tool to Data Link Connector (DLC). DLC is located under left side of instrument panel. Turn ignition switch to RUN position. Using scan tool, perform COOLANT GAUGE SWEEP TEST. If temperature gauge does not move up and down as commanded, go to next step. If temperature gauge moves up and down as commanded, concern may be intermittent. For aid in diagnosing intermittent problems, see PROBLEM DIAGNOSIS  under INTERMITTENTS.
