Temperature Gauge & Sending Unit: Justy

  1. Turn ignition switch to ACC position. If temperature gauge does not indicate below COLD, replace temperature gauge. If temperature gauge indicates below COLD, turn on ignition. Check fuse. Replace if blown.
  2. If fuse is okay, check for battery voltage between ground and Yellow/Green wire terminal of instrument cluster right connector. If battery voltage is not present, check wiring harness between fuse and instrument cluster.
  3. If battery voltage is present, disconnect temperature gauge sending unit connector. Connect an 18.5-ohm resistor between temperature gauge sending unit connector and ground. If temperature gauge indicates 240°F (115°C), replace sending unit. If temperature gauge does not indicate 240°F (115°C), replace temperature gauge.
