GENERAL DESCRIPTION
E944F092
The amount of intake air flow must be inputted to PCM in order to determine the fuel injection quantity. MAPS(Manifold
Absolute Pressure) calculates the amount of air indirectly as measuring the pressure inside of intake manifold. This
mechanism is also called Speed-Density Type.
MAPS transfers analog output signal which is proportional to the change of intake manifold pressure, then, with this signal
and RPM, PCM calculates the amount of intake air flow.
MAPS is mounted on surge tank to measure the pressure inside of intake manifold, and it consists of a piezo electric
element and hybrid IC which amplifies output signal from the element. A piezo electric element is a sort of a diaphragm
using piezo electric effect. One side of the diaphragm is surrounded with vacuum chamber while intake pressure is applied
to the other side. Thus, signals are outputted by the transformation of diagphragm according to the change of pressure
inside of intake manifold.
DTC DESCRIPTION
EDFAE6EB
Checking output signals of MAPS every 60 sec. under detecting condition, if an output signal is above 4.5V for more than
2 sec., PCM sets P1106.
