COMPRESSOR BYPASS SOLENOID VALVE INSPECTION [SKYACTIV-D 2.2]

id0113z7265500


Resistance inspection

1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2.  Remove the compressor bypass solenoid valve. (See COMPRESSOR BYPASS SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

3.  Measure the resistance between the compressor bypass solenoid valve terminals A and B.

Compressor bypass solenoid valve resistance (specification)
28—32 ohms [20 °C {68 °F}]
•  If not within the specification, replace the compressor bypass solenoid valve. (See COMPRESSOR BYPASS SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)


Airflow Inspection

1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2.  Remove the compressor bypass solenoid valve. (See COMPRESSOR BYPASS SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

3.  Inspect airflow between the ports under the following conditions.
