Purpose
The power MOS FET controls the blower motor rotation speed.
Function
The power MOS FET controls the supply voltage to the blower motor based on the gate voltage sent from the climate control unit, and adjusts the fan rotation speed (airflow volume).
Construction
The power MOS FET is installed to the A/C unit.
A transistor-type power MOS FET has been adopted and it is equipped with three electrodes, a source, a gate, and a drain.
Operation
The resistance between terminals B and A (between drain and source) changes according to the voltage (gate voltage) applied to terminal E (gate).
When the gate voltage increases, the resistance between terminals B and A decreases, allowing the current to flow easily. Therefore, the blower motor rotation speed increases.
When the gate voltage decreases, the resistance between terminals B and A increases, making current flow difficult. Therefore, the blower motor rotation speed decreases.
Fail-safe
Function not equipped.
Camshaft Position (CMP) Sensor
Purpose/Function
Detects the camshaft speed as basic information for mainly determining the
fuel injection timing and ignition timing.
Detects the camshaft speed and inputs it to the PCM as a CMP signal.
Construction
Intake CMP sensor
Installed on the cylinder head.

Fuel Pump Unit Removal/Installation
WARNING:
Fuel is very flammable liquid. If fuel spills or leaks from the pressurized
fuel system, it will cause serious injury or death and facility breakage. Fuel
can also irritate skin and eyes. To prevent this, always complete the “Fuel
