Thanks for the PDF, I went through the step by step instructions on how to diagnose this proplem and found a loose vac line I must have missed. Thanks, hopefully this will work.

Code 441 and 446

My 2000 GS400 started throwing codes 441 and 446 a couple days ago. I tried a new gas cap, but the code returned. Finally found one of the vacuum lines to the valve by the dipstick (if I get too technical, just let me know, ha ha) had come off, near the driver shock tower. The line did not fit tightly, and maybe the vent pressure in the gas tank caused it to blow off.
