I can't believe that either a) a topic on this does not exist, or b) that I couldn't find it. Searched here and trailvoy.
Anyway, 2007 Trailblazer with LL8. 103,500 miles. In Denver where it just got down to 10-20° F.
Never had any issues up until this point. Now getting P0418. I can also here the pump or valve making way more noise than normal for the first ~30 seconds after startup.
I think the more popular code is P0410??? I only get P0418. Also, after clearing it comes right back. No more than 1 drive cycle required.
Any ideas? Clean or replace the silver thing on the passenger side of the motor? Sorry I haven't kept up. I owned a 2002 TB a while back and since then my energy has been spent on my 2008 AWD SS. Way more simple motor. Haha.
Any help is appreciated!
