Villager V6-181 3.0L SOHC VIN 1 EFI (1997)
Temperature Sensor (Gauge): Description and Operation
With Analog Instrument Cluster
Description
Variations in current flow to the coolant temperature gauge occur at the water temperature indicator sender unit. When coolant temperature is low, the
resistance value of the water temperature indicator sender unit is high and very little current flows through the circuit. As the coolant temperature
increases, the resistance level drops, allowing more current flow.
