As explained to me and on my 05 Tundra, the P2445 code is mostly seen with a P0418 code and is caused by deteriorating air pump vanes. I found and installed a SAIS Bypass Kits from http://www.hewitt-tech.com and it saved me a $3500 repair that Toyota wanted to replace the system. I had to also get the pump replacement pack but they saved me a TON of money and were easy to install!

Hi, my son's truck, 07 Toyota Tacoma access cab, has both these codes too. Is this something he can fix himself or do you recommend just taking it to the mechanic? He's 20yrs old & has done his own oil changes/filters & changed his alternator, but he's not a "mechanic". Any info is greatly appreciated!
