WATER TEMPERATURE GAUGENJEL0042S01The water temperature gauge indicates the engine coolant temperature. The reading on the gauge is based
on the resistance of the thermal transmitter.
As the temperature of the coolant increases, the resistance of the thermal transmitter decreases. A variable
ground is supplied to terminal 19 (with tachometer) or 34 (without tachometer) of the combination meter for
the water temperature gauge. The needle on the gauge moves from ªCº to ªHº.
TACHOMETERNJEL0042S02The tachometer indicates engine speed in revolutions per minute (rpm).
The tachometer is regulated by a signal
+from terminal 32 (Gasoline engine models) or 439 (Diesel engine models) of the ECM
+to combination meter terminal 21 for the tachometer.
FUEL GAUGENJEL0042S03The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by a variable ground signal supplied
+from body grounds B9, B21 and B308
+through terminal 1 (Gasoline engine models) or 3 (Diesel engine models) of the fuel level sensor unit and
+through terminal 4 (Gasoline engine models) or 1 (Diesel engine models) of the fuel level sensor unit
+to combination meter terminal 20 (with tachometer) or 35 (without tachometer) for the fuel gauge.
SPEEDOMETERNJEL0042S04The combination meter provides a voltage signal to the vehicle speed sensor for the speedometer.
The voltage is supplied
+from combination meter terminal 23 (with tachometer) or 37 (without tachometer) for the speedometer
+to terminal 1 of the vehicle speed sensor.
The speedometer converts the voltage into the vehicle speed displayed.
