is the intake manifold air pressure; it provides a voltage varies as the intake air pressure. This
sensor is installed on the
Throttle Body Assembly.
3.5.5.2 Appearance
3.5.5.3 Operating Environment
This device is intended for use in inlet manifold for sensing air temperature and pressure
which shall withstand such an under hood environment.
●
Pressure Range: 20~102kPa
●
Temperature Range: -40~105°C
●
Relative Humidity: 0 to 100% RH.
●
Typical Voltage: The sensor circuit operates with a DC voltage reference of 5 ± 0.1 VDC.
3.5.5.4 Sample Cleaning
When necessary the samples may be cleaned in isopropyl alcohol or gasoline for one minute
with mating connectors in place and then air-dried.
3.5.6 Oxygen Sensor
3.5.6.1 Description and Working Principle
This sensor is a device for monitoring the residual oxygen in the exhaust of an internal
combustion engine. It is the feedback element for engine closed loop control.
