BME011318745W01

1. Remove the variable tumble control solenoid valve. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L3].)

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

  • If not as specified, replace the variable tumble control solenoid valve.
  • If as specified, carry out the "Circuit Open/Short Inspection".

## Circuit Open/Short Inspection

1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [L3].)

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.
  - Variable tumble control solenoid valve terminal B (harness-side) and PCM terminal 4T
  - Variable tumble control solenoid valve terminal A (harness-side) and main relay terminal C (harness-side)

### Short circuit

  • If there is continuity, the circuit is shorted. Repair or replace the harness.
  - Variable tumble control solenoid valve terminal B (harness-side) and body GND
  - Variable tumble control solenoid valve terminal A (harness-side) and power supply
