.
- Put a finger to the purge solenoid valve and verify that there is vacuum applied with engine at idle and warmed up.
- If there is no vacuum, inspect the following:
- Wiring harness and connectors (Main relay-Purge solenoid valve terminal B-PCM terminal 2S)
- Purge solenoid valve (stuck close) (See PURGE SOLENOID VALVE INSPECTION
.)
- MAF, APP1, APP2, TP REL and LOAD PIDs (See PCM INSPECTION
.)
