Can a faulty purge valve cause the check engine light CEL to stay on in Changan Karvaan?

A failing o r stuck purge valve often triggers EVAP-related error codes. Are Karvaan owners noticing consistent CEL alerts even after clearing codes, possibly due to unresolved valve problems?

Yes. A malfunctioning purge valve will:

Trigger EVAP-related fault codes like P0441, P0446, P0455

Cause the CEL to stay on, especially if the valve is stuck o r leaking

Sometimes, even after clearing the code, the light returns if the underlying issue isn’t resolved
