Hello leakyseals,
I read your solution on the P0440, P0441 and P0446 code. My car is a 2002 Toyota Camry LE 2.4L with 106k miles on it. These three codes came on the same time for mine with P0420. I will be grabbing an OEM gas cap tomorrow to see if it fixes the issue. However, worst case scenario that it doesn't work, how would I proceed to check if the problem is from vacuum switching valve? Should I use an OHM meter and test it? Would it just be the vsv that needs to be checked or should I also check something else? Thank you leakyseals. I hope to hear from you soon.
