If this is an ELANTRA (you did not give enough information), it is on the top of the Fuel Tank and needs to be replaced. This is a very common problem.

But check your electrical wires and hoses from the Fuel Tank and Canister but the most common issue is the Purge Valve on top of the Fuel Tank

Check engine light up


This DTC tests for undesired intake manifold vacuum flow to the evaporative emission (EVAP) system. The control module seals the EVAP system by commanding the EVAP canister purge valve Closed and the EVAP canister vent valve Closed. The control module monitors the fuel tank pressure (FTP) sensor to determine if a vacuum is being drawn on the EVAP system. If vacuum in the EVAP system is more than a predetermined value within a predetermined time, this DTC sets.

What does check engine light code po496 mean?

DTC P0496 is defined as Evaporative Emission (EVAP) System Flow During Non-Purge.

If the Evap purge valve does not seal properly, fuel vapors could enter the engine at an undesired timing causing drivability concerns. The control module tests for this by commanding the EVAP purge valve OFF closed and vent valve ON closed, sealing the system, and monitoring the FTP for an increase in vacuum. If the control module detects that Evap system vacuum increases above a calibrated value, DTC P0496 will be set.

The first step would be to simply clean the valve and see if that helps. The purge valve will be an inexpensive part so I'd usually just replace it instead of trying to test it to thoroughly.

Hope this helps and just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer. Thank you for using FixYa.
