INTAKE SHUTTER SOLENOID VALVE INSPECTION
A6E401613937201
Note
• Perform the following inspection only when directed.
• The inspection includes both intake shutter solenoid valve (half) and intake shutter solenoid valve (full).
1. Inspect airflow between the ports under the following conditions.
• If not as specified, replace the intake shutter solenoid valve.
• If as specified, carry out the “Circuit Open/Short Inspection”.
Intake Shutter Solenoid Valve (Half) Circuit Open/
Short Inspection
1. Disconnect the PCM connector. (See F2–64 PCM
REMOVAL/INSTALLATION.)
2. Inspect the following wiring harness for an open
or short circuit (continuity check).
Open circuit
• If there is no continuity, the circuit is open. Repair
or replace the harness.
— Intake shutter solenoid valve (half) terminal A
(harness-side) and PCM control relay
terminal C (harness-side)
— Intake shutter solenoid valve (half) terminal B
(harness-side) and PCM terminal 74
Short circuit
• If there is continuity, the circuit is shorted. Repair or replace the harness.
— Intake shutter solenoid valve (half) terminal A (harness-side) and GND
— Intake shutter solenoid valve (half) terminal B (harness-side) and power supply
Intake Shutter Solenoid Valve (Full) Circuit Open/Short Inspection
1. Disconnect the PCM connector. (See F2–64 PCM REMOVAL/INSTALLATION.)
2. Inspect the following wiring harness for an open
or short circuit (continuity check).
Open circuit
• If there is no continuity, the circuit is open. Repair
or replace the harness.
— Intake shutter solenoid valve (full) terminal A
(harness-side) and PCM control relay
terminal C (harness-side)
— Intake shutter solenoid valve (full) terminal B
(harness-side) and PCM terminal 100
Short circuit
• If there is continuity, the circuit is shorted. Repair or replace the harness.
— Intake shutter solenoid valve (full) terminal A (harness-side) and GND
— Intake shutter solenoid valve (full) terminal B (harness-side) and power supply
