Lol oh yea. They'll do that slick stuff too😄 wait so how do u clear the code? I couldn't find the reset button on mine. & actually a service tech called me this morning, said bring it2 the shop, they'll see if I need a cap or whatever & take care of it 4me, since I just got the car Sunday ya know? I think they said if anything goes wrong within 30 days ,they'll fix it. So I'm good anyway. He said dont worry. & my oil change/tranny change, all the specs were done at the same time (1,000miles ago) so everything seems official so far-I have no idea if that is considered a warranty item or not.
Where I live, we have to go for an emissions test/inspection every two years. I always purchase a new gas cap right before the test. They are around $5 on rockauto.com
For me... its not worth the hassle of failing the test, going to get a new cap and waiting in line for a re-test.
I know on my versa, you have to turn the cap until you hear one click. Other gas caps instruct you to turn it until you hear 3 clicks.
You may want to ask if you have an OE gas cap or an aftermarket gas cap??
My girlfriend didn't close her cap completely on her Dodge and it threw a P0457 code. I just closed it properly, cleared the code and ran a drive cycle.. all good. Now she insists on me filling her car with gas (when it needs it). I think she left it loose on purpose as she hates pumping gas.
