NOTE:
Perform the following procedure only when directed.
1. Remove the purge solenoid valve without disconnecting the evaporative hose. (See PURGE SOLENOID VALVE REMOVAL/INSTALLATION [LF].)
2. Verify that the airflow is as indicated in the table.
If as specified in the table, perform the “Circuit Open/Short Inspection”.
If not as specified in the table, inspect the purge solenoid valve. (See PURGE SOLENOID VALVE REMOVAL/INSTALLATION [LF].)
Measured condition
Continuity between A—B
When voltage is not applied between terminals A and B
No airflow
When voltage is applied between terminals A and B
Airflow detected
1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [LF].)
2. Inspect the following wiring harnesses for open or short circuit (continuity check).
Open circuit
If there is no continuity, there is an open circuit. Repair or replace the wiring harness.
Purge solenoid valve terminal A and PCM terminal 2C
Purge solenoid valve terminal B and main relay
Short circuit
If there is continuity, there is a short circuit. Repair or replace the wiring harness.
Purge solenoid valve terminal A and power supply
Purge solenoid valve terminal A and body ground
Purge solenoid valve terminal B and body ground
