Signal WaveformFig.1) Duty control [EEGR Motor (-)] at deceleration or idleFig.2) Duty control [EEGR Motor (+)] at acceleration
Inspection[Motor]1.Turn the ignition switch OFF.2.Disconnect the EEGR valve connector.3.Check that the EEGR valve is stuck by foreign material. 4.Measure resistance between motor 1 and 3 control terminals of the motor.
DescriptionThe evaporator temperature sensor will detect the evaporator core temperature and interrupt compressor relay power in order to prevent evaporator from freezing by excessive cooling. The evaporator temperature sensor has the Negative Temperature Coefficient (NTC).
Description The photo sensor is located at the center of the defrost nozzles.The photo sensor contains a photovoltaic (sensitive to sunlight) diode. The solar radiation received by its light receiving portion, generates an electromotive force in proportion to the amount of radiation received which is transferred to the automatic temperature control
