Temperature Gauge: Description and Operation
How the Circuit Works
The indicator lights are controlled by different conditions in their associated systems. Refer to each associated system to see its entire schematic.
Engine Coolant Temperature Gauge
The engine coolant temperature gauge has two intersecting coils wound around a permanent magnet rotor. Voltage applied to the coils, through fuse 9 (in
driver's under-dash fuse/relay box), generates a magnetic field. The magnetic field, controlled by the ECM or PCM causes the rotor to rotate and the
gauge needle to move. As the ECM or PCM varies the current, current through the gauge coils changes, moving the gauge needle toward the coil with
the strongest magnetic field.
