Temperature Gauge: Description and Operation
CIRCUIT OPERATION
Engine Coolant Temperature Gauge
The engine coolant temperature gauge consists of two intersecting coils wound around a permanent magnet rotor. When voltage from the CB-11 fuse is
applied to the coils, a magnetic field is generated. This causes the rotor to rotate and the gauge needle to move. The magnetic field is controlled by the
sender(2.2L)/ ECT sensor through the ECM or PCM (3.2L). As the resistance in the sender/sensor varies, current through the gauge coils changes. The
gauge needle moves according to the changing magnetic field.
