Manifold Absolute Pressure Sensor (MAPS) is a speed-density
type sensor and is installed on the surge tank. It senses absolute
pressure of the surge tank and transfers the analog signal proportional
to the pressure to the ECM. By using this signal, the ECM calculates the
intake air quantity and engine speed.
The MAPS consists of a piezo-electric element and a hybrid IC
amplifying the element output signal. The element is silicon diaphragm
type and adapts pressure sensitive variable resistor effect of
semi-conductor. Because 100% vacuum and the manifold pressure apply to
both sides of the sensor respectively, this sensor can output analog
signal by using the silicon variation proportional to pressure change.

SRS Care
The SRS is virtually maintenancefree and so there are no parts you can safely
service by yourself. If the SRS air bag warning light does not illuminate, when
you turn the ignition on, or continuou ...
