EGR SOLENOID VALVE (VACUUM) INSPECTION
A6E401618741201
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. 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
