evap description
hey all. new to the site and new yota owner. could someone give me a little evap help. as a gm mechanic i'm familiar with how they all generally work but need a little extra info for the yota. i've got a 2002 tacoma xtra cab and a 4cyl. i have dtc 440 and 441 and sometimes it throws in a 446. my questions are... two valves on the left fender well, one has the evap port (purge valve) what is the other? and were is the pressure sensor located? on the tank? i see on the purge valve says 12v. when i turn it on w/ scan tool, reading volts w/dvom it goes from about 2.5 to 5v. is that the norm. i'm using matco determinator scanner. thanks.
