Howdy guys, recently began to get the p0401 code on my 1999 toyota camry (4 cylinder standard), and I'm already over inspection so I need to get this fixed quickly. Anyway I went through the diagnostics set out in Haynes manual and my egr valve holds vacuum, modulator seems to be fine. So I pinpointed it down to the vsv, got the car on blocks and for the life of me can barely see it, never mind unbolt it and get it out. Is there a special trick? There seems to be one bolt I could get off but I don't see any others. This is my first in depth repair like this so any help would be greatly appreciated! Theres not much for 4 cylinder tutorials on the web. Also my brake light has been on for the past 3 months even though brake fluid level is almost at max and emergency brake is down, any ideas?
