Question
358429
I think I am following all the posts correctly, can someone confirm?
P0446:
Most likely cause is a clogged evap vent:
Order AC Delco p/n: 214-2082
Purchase ~10' of 5/8" bulk radiator hose
Replace vent solenoid and relocate filter box.
P0449:
Most likely caused by a malfunctioning Evaporative Emission Canister PURGE solenoid.
AC Delco p/n: 214-1680
R&R part.
P0449 - How can I test the purge solenoid to confirm that it is the cause?
Edit to add: I was able to crawl under my truck after getting home from work. It appears as the filter box is already located above the transmission as described in the P0446 TSB.
(My apologies in advance for posting yet another P0446/P0449 thread...)
