2002 hyundai accent error po441, po442

Question

i see this error code for nissan but not for hyundai. does that apply to hyundai too?

Answer 1

P0441 is for low purge volume and the P0442 is for a small leak in the evap system. These are related and many times it's the purge control valve. You may have to have a smoke test done to locate the actual leak in the system since it can be as small as a pin hole created by a needle.
