BME011618741W03

  Note

  • Perform the following inspection only when directed.

1. Remove the EGR control solenoid valve.

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

  • If not as specified, replace the EGR 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 [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.
  - EGR control solenoid valve terminal A (harness-side) and PCM control relay terminal C (harness-side)
  - EGR control solenoid valve terminal B (harness-side) and PCM terminal 77

### Short circuit

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