Temperature Gauge: Description and Operation
Engine coolant temperature gauge
-
When the ignition key is at the "ON" position, the engine coolant temperature gauge is activated.
-
When the engine coolant temperature is high, the unit's resistance is low and current flow in the circuit is high, so the gauge's indicator indicates in
the "H" area.
-
When the engine coolant temperature is low, the unit's resistance is high and current flow in the circuit is low, so the gauge's indicator indicates in
the "C"area.
