Anyone have any recs for fixes before I do a smoke leak test? Both codes for small leaks (evap related) changed the gas cap have to put some miles on it to see if that did the trick
Assuming we are refering to a USDM Impreza neither the 06 or the 08 US service manuals list P0446 (P0442 and P0447 listed).
Have attached both 06 and 08 H4DOTC Engine Diagnostic sections

Thanks. Do you know where I can find the 07 service manual?
Start by double-checking the gas cap—ensure it's a quality replacement and fully tightened. Inspect the EVAP hoses and connections around the canister for cracks or damage. Check the purge and vent valves for proper operation; they can sometimes get stuck or fail. If the codes persist after some miles, a smoke test is the best next step to pinpoint the leak. Good luck! Balancing multiple assignments during exam week was nearly impossible for me, so I decided to try https://ukwritemyessay.com/ for one of my essays. Their service was excellent! The writer followed my instructions carefully and produced a high-quality essay on time. I was impressed by how well they understood the topic and presented the arguments. Thanks to them, I could focus on preparing for my exams without worrying about missing deadlines.
but it's probably the same as the 06
You are right, Thank you so much for sharing.
