Temperature Gauge

  1. Turn ignition off. If gauge needle does not drop below "C", replace it. Turn ignition on and check fuel gauge operation. If fuel gauge does not work check fuse and wiring to terminal 21 on back of instrument cluster.
  2. Unplug temperature sending unit wire at sending unit. Connect a 52 ohm resistor between wire and ground. Temperature gauge should indicate about 190° F (86° C). If so, replace sending unit. If not, check for 7 volts at sending unit wire.
  3. If voltage, is present, replace temperature gauge. If no voltage is present at sending unit wire, check for 7 volts at terminal 8 of 12-pin connector on instrument cluster (Yellow/Green wire). If voltage is present, repair wiring to sending unit. If no voltage, replace temperature gauge.
