8-6.9. Cylinder Head Temperature (CHT) Sensor
Each control channel in the ECU has an independent Cylinder Head Temperature (CHT)
Sensor inputs. The CHT Sensor uses a bayonet style mounting system wherein an adapter
is threaded into the cylinder head and a spring-loaded locking ring on the sensor secures
the attachment. The sensing element in each sensor is a thermistor, which changes
resistance with temperature in a linear, repeatable manner. Measuring the resistance of
the sensor allows an accurate determination to be made of temperature at the sensor tip.
