2.  Monitor the following signals using the PID/data monitor.

•  EGR solenoid

•  Mass air flow (MAF)

3.  Using the “SEGRP” simulation function, verify that the mass intake airflow amount changes.

•  If the mass airflow amount does not change, inspect the following:

―  EGR solenoid valve

―  Wiring harness and connector open circuit (main relay—EGR solenoid valve—PCM)

―  Vacuum hose disconnection or damage

4.  Clear all DTCs stored in the PCM referring to the “AFTER REPAIR PROCEDURE”.
