Description
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.
Other information:
Inspection
1.
Turn the ignition switch OFF.
2.
Disconnect the temperature control actuator connector.
3.
Verify that the temperature control actuator operates to the cool position
when connecting 12V to terminal 3 and grounding terminal 7.
Replacement
1.
Disconnect the negative (-) battery terminal.
2.
