Intake Air Temperature Sensor
The intake air temperature sensor (A) detects the
temperature of the intake air after it has passed the
turbocharger. The sensor portion that detects the
temperature contains a thermistor (1). The thermistor
(1), which has an electrical resistance that changes with
temperature, is used to detect the intake air temperature.
Coolant Temperature Sensor
The coolant temperature sensor (B) is installed near
the thermostat and detects the engine coolant
temperature. This sensor is a thermistor (1) type.
Fuel Temperature Sensor
The fuel temperature sensor (C) is installed on the
fuel intake side of supply pump and utilizes the
characteristics of a thermistor (1) in which the electric
resistance changes with the temperature in order to
detect the fuel temperature.

Intake Air Pressure Sensor
This sensor is a semiconductor type sensor.
measures intake air pressure utilizing the piezoelectric
effect that when the pressure on the silicon element in
the sensor changes, its electrical resistance changes.
