Temperature Gauge
- If temperature gauge needle does not move at all, check for blown fuse or loose wire harness connector. If fuel gauge is inoperative also, inspect voltage regulator for malfunction.
- Disconnect sending unit wire. Connect a resistor between wire and ground. Use the RESISTANCES FOR TEMPERATURE GAUGE TESTING table to compare gauge reading. Change resistance and recheck. If gauge readings are as shown in tables, replace sending unit. If not, repair wiring or replace gauge.
