Description and operation
Description

Manifold Absolute Pressure Sensor (MAPS) is a speed-density type sensor 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. This silicon diaphragm type element has pressure sensitive variable resistor effect of semi-conductor. One side of silicon diaphragm is 100% vacuum and manifold pressure is applied on the other side. Hence, output is gained from the silicon variation in proportion to the pressure change.

Removal
1.

Switch "OFF" the ignition and disconnect the negative (-) battery terminal.

2.

Remove the engine cover.

(Refer to Engine Mechanical System - "Engine Cover")

3.

Disconnect the manifold absolute pressure sensor connector (A).

4.

Remove the installation bolts (B), and then remove the sensor from the intake manifold.

Installation
  

Install the component to the specified torques.

Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.

Insert the sensor in the installation hole and be careful not to damage it.

1.

Install in the reverse order of removal.
