Temperature Gauge: Description and Operation
Coolant Temperature Gauge 47C
The temperature gauge displays the temperature of the engine coolant.
When the ignition switch is in the Drive position, 12 V is supplied to pin 2 of the temperature gauge from pin 22 of EDU 210. Engine coolant
temperature sensor 45 is connected to the EDU which, after processing the information, sends a signal of 1-9 V to pin 7 of the tank/temperature unit.
1 V = min. temperature.
9 V = max. temperature.
Temperature gauge 47C, fuel gauge 47A, instrument lighting lamps 18, and indicator lamp 47I are connected to ground via pin 5.
