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.

Fan speed control
The ignition switch must be in the ON position for fan operation.
The fan speed control knob allows you to control the fan speed of the air flowing
from the ventilation system. To change the fan ...

Tire wear
1.
Measure the tread depth of the tires.
Tread depth [limit] : 1.6 mm (0.063 in.)
2.
If the remaining tread (A) depth is less than the limit, replace the tire.
