INLET PRESSURE TEMPERATURE SENSOR

The intake air pressure and temperature sensors include:
intake air pressure and intake air temperature sensors.
The pin diagram is shown at【A】in the left fi gure.
1: Inlet pressure signal output OUTPUT SIGNAL
2: Supply voltage SUPPLY VOLTAGE
3: Thermistor NTC
3: Sensor ground GROUND
The core of the intake air temperature sensor is the
thermistor that reacts quickly to temperature.
The intake pressure sensor passes through the air
pressure channel on the throttle body and the main
throttle body.
The channels are connected together to detect the
absolute pressure of the intake air.When the pressure
in the main channel changes, the output voltage of the
pressure chip will also change accordingly.Through the
corresponding relationship between the output voltage
and the absolute pressure of the main channel, the
ECU can obtain the absolute pressure value of the main
channel at this time.
!
When disassembling the intake air pressure and
temperature sensor, to ensure that there is no
condensed water on the pressure sensitive element, it
is forbidden to use high-pressure gas to impinge on the
vacuum element during the maintenance process.
