Neon L4-2.0L DOHC (1996)
Temperature Gauge: Description and Operation
CIRCUIT OPERATION
The temperature gauge is connected to the engine coolant temperature sensor on the G20 circuit. The engine coolant temperature sensor for the
gauge is a combination unit. One side of the unit is used for the Powertrain Control Module (PCM) and the other side for the cluster. The sending
unit is case grounded to the engine.
The logic driven gauge moves in response to the measured resistance of the engine coolant temperature sending unit.
