What does this code mean?
The EVAP system detects excessive purge behavior; the exact test may infer flow from tank pressure or vacuum response rather than measure vapor flow directly. It is distinct from a small-leak code. A purge valve is a possible investigation point, but the cited manufacturer sequence does not treat the code alone as a confirmed valve failure.
Sources and interpretation [1]
A code identifies a detected condition, not a part that must automatically be replaced.
Before replacing a part
Retain the suffix and inspect the applicable EVAP test sequence. Separate debris contamination, valve sealing and leak-detection faults using the prescribed tests. Do not apply another manufacturer's vacuum threshold or infer that every case needs a purge valve.

Can I keep driving?
A code alone cannot establish whether driving is safe. A flashing malfunction light, severe shaking, overheating, oil-pressure warning or loss of braking or steering needs prompt attention. Stop in a safe place and seek assistance when control or engine safety is affected. Follow the vehicle handbook.
