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.
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
Diagnosis With GDS1.The heating, ventilation and air conditioning can be quickly diagnosed failed parts with vehicle diagnostic system (GDS).※ The diagnostic system (GDS) provides the following information.(1) Self diagnosis : Checking the failure code (DTC) and display.
