2006 sentra 1.8L How to locate and repair code P2101

Question

car starts good for 3 or 4 days then fails to start after sitting for 8 t0 12 hours. Turns over but sounds like not getting any air. After cranking a lot of times it will eventually start. The fuel tank air vent seems to be plugged and takes forever to put fuel in, keeps spitting back. Can these problems be related and how to fix. Thanks Dw

Answer 1

P2101 and P2119 are related to the throttle body, I think the throttle plate is going to be stuck closed.

Try to clean the throttle body first most likely it is dirty (if the throttle body has not gone bad yet.)

you will have to do an idle air relearn after the car starts up (after cleaning the throttle body or replacing it)
