CEL PO496

Hi,

My check engine light came on and the code is PO496. Does anyone know what this is and why it came on? Thanks

CEL P0496 (EVAP System Flow During Non-Purge) normally means gas cap isn't on correctly.

I checked that one, do you think that because I had my car modded that it could be that.

I would say drive the car around and see if the computer resets itself. Did you recently mod your car?

Yeah about 2 weeks ago. Just wanted to make sure I wasn't doing any damage, but the tuner said he will fix it if it doesn't fix itself.
