8) Manifold absolute pressure sensor : MAP
The manifold boost pressure(MAP,
PthP) sensor detects the absolute air
and fuel pressure within the engine
manifold.
Information from this sensor, along
with air charge temperature
information is used to calculate
density of the mass charge being
delivered to each cylinder.
9) Humidity sensor
Humidity sensor detect atmospheric
pressure to determine the air density
using to control of engine control
module.
10) UEGO sensor
The Universal Exhaust Gas Oxygen
(UEGO) sensor is the key part of the
engine control system.
It measure the oxygen content in the
exhaust gas stream, and feed back
this information to the engine control
module(ECM) to control the fuel/air
quantity to the engine.
