Coupe GT L5-2226cc 2.22L SOHC (KX) (1986)
Coolant Temperature Sensor/Switch (For Computer): Description and Operation
Fig. 28 Coolant Temperature Sensor
The coolant temperature sensor, Fig. 28, is a negative temperature coefficient resistor (resistance increases as the temperature decreases). It is located in
the cylinder head next to the #1 spark plug. The resistance signal is used by the control unit to advance the ignition timing when the engine is cold and
the manifold pressure is below 1.0 bar (0 in. vacuum). The temp sensor signal is also used to correct the fuel mixture for various temperature conditions.
