ENGINE FUEL AND EMISSION CONTROL SYSTEM 6C-43
Intake manifold air temperature and pressure
sensor
This device is made up of a temperature sensor and a pressure
one (1).
It’s placed on intake manifold, and measuresover feeding air
pressure and temperature.
Both values, dire used by the control unit to measure the air flow
introduced in cilinders and therefore the fuel ammount sent to
injectors.
Resistance valves in fuction of temperature:
