INTAKE SHUTTER SOLENOID VALVE INSPECTION [MZR-CD (RF Turbo)]

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 PCM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)

2. Inspect the following wiring harness for open or short (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 PCM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)

2. Inspect the following wiring harness for open or short (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
