SYMPTOM
MIL comes on during vehicle operation.
POSSIBLE CAUSE
Due to variations in the purge control solenoid valve spring, the valve wears unevenly and intermittently sticks. This may
result in setting DTC P0441 (Evaporative Emission (EVAP) System Purge Flow Malfunction).
CORRECTIVE ACTION
Replace the purge control solenoid valve, then do an EVAP system function test with the i-HDS.
