Hi all,

I got a P0446 engine code a few days ago and after removing the engine cover figured it out pretty quick. A hose snapped in half (pictured). I took the hose to AutoZone but they told me I’d need to order the part from Lexus. Problem is I can’t find the part number. Anyone able to help me with a part number or a serviceable replacement? Thanks!

Edit: spoke with a local Lexus dealer and looks like part number is 2382950100. Posting in case anyone in the future needs :-)

 

Unless someone knows the part number, you'll probably need to pour through the parts diagrams on any of the Lexus OEM parts websites or go to a dealer to get their help. I replaced a bunch of vacuum lines on my 300 and it was a pain because the OEM parts diagrams are so poor and you can't really just use generic vacuum lines because the OEM ones are molded to shape.

 

Here take a look and find your part number:
