My check engine light is on so I ran a scan with my personal car code reader & got code p0496. I called chevrolet & they told me its p0442. Which is correct?


p0496 is evap emission is high purge flow fault, p0442 is emission control system( small leak) the meaning is about the same. check for a bad gas cap first. sometimes this will set a check engine light. loosen cap and see if this is the problem. if it is. usually if you turn cap only a little the light will go out. but if bad enough just change cap.

I have a 2003 Kia Spectra and the check engine light came on this morning, I took it to VIP and they ran the machine that tells you the code, but they won't tell you what the code means, you have to figure...


A code P0442 most likely means one or more of the following has happened:
  • A loose or improperly affixed gas cap
  • A non-conforming gas cap (i.e. not factory/original brand)
  • A small leak/hole in a fuel vapor hose/tube
  • Other small leak in EVAP system
  • Faulty vent o-ring seal
  • In other words, you PROBABLY have a vaccume leak. :-)
