Other Fuel System Fuel Injection System Problems of Toyota 4Runner

Driving last week and check engine light along with traction control light came on. Hooked my ob2 scanner to port but came up with no codes. Drove it a few more days and eventually lights went out. Fast forward a week and lights came back on. Same routine with the ob2 but this time the code p2443 came up. Googled it and " secondary air injection system switching valve stuck closed bank 2". Found out there is a huge history with this problem not only with my 4runner but with tacomas, tundras and sequoias. With certain years of tundras and sequioas, Toyota has paid for this fix. Why not the 4runners and tacomas??same problem!! this whole thing is a big sham . It will cost about $2000 plus for this issue to be fixed. Where I come from, this is robbery. Knowingly selling vehicles with a expensive problem and not recalling them to be fixed.

The secondary air injection pump is sending error messages and the vehicle is now in limp mode. The vehicle will not go over 30mph.

My check engine light came on along with vsc trac. After taking vehicle to dealership I was told that the repair would cost $2,048. 73 due to the air pump being stuck in off position. While Toyota in response to reports of air induction pump assemblies and/or air injection switching valves issues on their 2007-2010 tundra and 2008-2010 sequoia models, Toyota has decided to increase its warranty on these parts and is even offering a reimbursement if you already had this issue fixed. My vehicle has the identical engine of the above-named vehicles but Toyota does not offer any help with the 4runner. It is my understanding that if I do not get the problem fixed it becomes a huge problem within federally mandated emissions requirement.
