9000 CSE L4-2290cc 2.3L DOHC Turbo EFI (1995)
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.
Instrument Lighting 18
Backlighting of the instruments is controlled by rheostat 16 (lighting for controls) via pin 6.
Indicator lamp 47I
The indicator lamp for the right-hand direction indicators is controlled by flasher relay 23 via pin 4.
