• The CHT sensor is Installed to the cylinder head.
• The CHT sensor is a thermistor device in which
resistance changes with the temperature.
• The CHT sensor provides engine cylinder head
temperature information, and the signal is used
by the PCM to estimate the engine coolant
temperature.
• The CHT sensor is a thermistor type sensor in
which the resistance changes according to the
cylinder head temperature.
• The resistance decreases if the cylinder head
temperature increases, and conversely increases
if the cylinder head temperature decreases.
