I have a 2011 Nissan versa S hatchback 4cyl 1.8l and it's throwing code P0507. I took it to a mechanic in which they inspected and crossed out that it's not an air leak. They replaced my throttle body and I replaced the PCV valve based off of their recommendation. When I changed the PCV valve with an after market part the check engine light went off until the end of the day when I parked my car on a hill in an incline the light came right back on. I purchased a Nissan PCV valve to replace the after market one because I figured the car was rejecting the after market part and that it wasnt compatible for my Versa's performance. I switched out the valve, relearned the system and boom light off, RPM's normal again, and smooth cruising until I got home and parked on a hill in an incline again. I'm stumped. I've changed out my air filters a month ago. I don't know what else could be causing this code to keep reappearing.
