P0442 Check engine light code - Evap leak?
Anyone have p0442 code before with the VSC light and TRAC light on? I used to have P0446, P0455, P0441, and P2418; but I changed the pressure sending valve on the charcoal canister. Now I have P0442 and I replaced the gas cap like most have suggested and the code is still there. The car is 2005 Lexus LX470 with 166k miles.

p0442 is a code for a small evap leak. This could be a seal on the cap. Check for rust around the filler neck or a non OEM cap can cause this. Also, the purge valve can stick and not close completely during its self-test and set a p0442 code.
