Was wondering if anyone ever had this and how to fix. My CEL came on a few days ago. ran the scan and got this code. please let me know. thanks
 
Sounds like you have a problem with your evap pressure sensor or somewhere in the evap system. I would cech for broken evap hoses,plugged vsv solenoid or a stuck open vsv sensor.
 
I got this code last week as well. Had a buddy reset it with the OBD tool. It came back on two days later and went away by itself a day later. Came back on this morning but went away by the time I got to work. If it goes on and goes off by itself, it's probably just the gas cap. Just have to loosen it and retighten until it clicks a few times. Seems to be a common issue with Infiniti's and Nissan's from the articles I've read.
 
thanks guys. yeah it went away after a few days. its been off since i posted the thread. hoping its just the gas cap.
