BME011618741W01
-
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 A (harness-side) and GND
-
- EGR solenoid valve (vacuum) terminal B (harness-side) and power supply
