TEMPERATURE GAUGE INDICATION DIAGNOSIS CHART

CONDITION POSSIBLE CAUSES CORRECTION
TEMPERATURE GAUGE READING IS INCONSISTENT (FLUCTUATES, CYCLES OR IS ERRATIC).
  1. Normal reaction to fan and/or thermostat cycle (Figure ), Examples B and C. During cold weather operation with the heater blower in the high position, the gauge reading may drop slightly (Figure ), Example D. Fluctuation is also influenced by outside temperature and heavy loads (Figure ), Example E.
  2. Gauge reading rises when vehicle is brought to a stop after heavy use (engine still running) (Figure ), Example F.
  3. Gauge reading high after restarting a warmed-up (hot) engine.
  4. Temperature gauge or engine coolant temperature sensor defective or shorted. Also, corroded or loose wiring in the electrical circuit.
  1. A normal condition: No correction is necessary.
  2. A normal condition. No correction is necessary. Gauge reading should return to normal range (Figure ), Example A, after vehicle is driven.
  3. A normal condition. No correction is necessary. The gauge should return to normal range (Figure ), Example A, after a few minutes of engine operation.
  4. Check operation of gauge or engine coolant temperature sensor and repair, if necessary.
