Hey guys does anyone have any specific places to look re this error code other than what is described at https://www.clublexus.com/forums/rx-...questions.html

I recently replaced idle air control valve & rear o2 sensor & the little sensor that reads air intake just up from air filter. All codes cleared for a couple months, then this one came up. I don't see any loose vacuum hoses (could be missing one obviously, as there is so much clutter under hood) and gas cap seal appears to be ok

Any other ideas ie: a "usual culprit"? Thx for any ideas u can pitch!

If you do a search you may find that I have posted about this code before, but I'm not absolutely certain. I do recall that several years ago I had a code that led me to the charcoal cannister in the evaporative control system, at the back of the RX. I replaced one of the vacuum control valves, and some rotten vacuum hoses. However, the vacuum control valve only pertained to 99 and perhaps '00 RX; the system was changed thereafter. Also, I had to get the valve from Toyota - Lexus would not sell it separately from the entire cannister assembly.
