SES Code P0452
 

O'Reilly had a ton of possible causes listed, how do I go about fixing this?

Truck still drives fine.

Here is a link to the trouble code which will walk you through the process of trouble shooting the code from start to finish and should identify the problem:
P0452 - Evaporative Emission Control System Pressure Sensor Low Input

As well as a link that will show you the threads where others have posted about this same code --> Search for "P0452"

Thanks for those. I read them over and looked through the search results, and honestly, a lot of it went over my head. I am pretty mechanically inclined but I have limited access to tools and only know the location of major parts in an engine bay.

Is there a common problem that causes this code? Or since I don't have many tools, should I just break down and take it somewhere to fix?

Also, is this something that needs to be fixed ASAP? I'm starting a new job next Wednesday, and moving between now and then, so if I could use the truck until after then it would be awesome.

Thanks!

driving around today, light went off for about 2 hours. Turned it on after a brief stop and it came back on. Any reason that would happen?
