2008 Toyota Corolla Q&A
2008 Toyota Corolla Question: what happoens when the charcoal cannister needs to be changed and is not?
The charcoal cannister was probably the problem in the first place. Vapor recovery systems errors are diff. to diagnose and find the cause without a "smoke test". The cap may or may not have been a problem. At least the true issue has probably shown up now. - csubak30
