EGR SOLENOID VALVE (VACUUM) INSPECTION [MZR-CD (RF Turbo)]

BME011618740203

  Note

  • Perform the following inspection only when directed.

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

  • If not as specified, replace the EGR solenoid valve (vacuum).
  • 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 solenoid valve (vacuum) terminal A (harness-side) and PCM control relay terminal C (harness-side)
  - EGR solenoid valve (vacuum) terminal B (harness-side) and PCM terminal 99

## Short circuit

• If there is continuity, the circuit is shorted. Repair or replace the harness.

  - EGR solenoid valve (vacuum) terminal B (harness-side) and GND
  - EGR solenoid valve (vacuum) terminal B (harness-side) and power supply
