1. The secondary air injection valve and/or air injection pump. 2. Sometimes the vehicle will go into "limp" mode and only go 35 mph. If the switch valve is stuck "closed" like mine, the car may not be able to dilute the exhaust fumes and the fumes and travel into the cabin of the vehicle. 3. Yes, check engine light code was read as P2441. 4. No, the vehicle can not be driven at this time. 5. No, and around July 24th the check engine light came on. The symptoms continued to get worse. In short, Toyota has issued extended warranties and reimbursements for this design flaw for Tunda's 2007-2010. The design flaw being the air pumps allow water and debris to be sent into the air injection valves. My truck being a 2011 was never alerted to this issue or covered due to the year of my vehicle. The issue is my truck is the SAME generation truck as the 2007-2010 trucks. …
* According to the different computers codes the issue is Secondary Air Injection Pump failure. *Driving on the highway I had the limp mode which created a drastic velocity drop from 70 mph to 40 mph which created a situation that almost ended up in having another car hitting me from behind. this incident occurred a coupled of times in highway but in most cases just when starting a cold engine * problem is widely encountered online by other users [redacted] * check engine and track lights off * First time it occurred is 10/02/2023
Well known issue with V8 Air intake pump and assembly causes truck to go into limp mode. Very dangerous in Atlanta traffic. Toyota enhanced warranty but did not recall. My repair was $3000 as I was 3 weeks out of warranty.
Cam tower seal problems currently my Tundra is having a camshaft tower seals problem/gasket. I thought my truck was going to catch on fire several times with my grand kids inside while driving.'.with it smoking on the passenger side. This is highly unusual for a Toyota. I thought it would have stopped by now, but it has not. This has been an ongoing problem since I purchased the truck. In doing my research, which I understand is a big repair job as it requires dismantling part of the engine; this is a major problem with this model year that I currently own (2011). There are also several other model years that it is also happening as well (2011-13), in which again can cause the truck to catch fire, harming or even killing someone. If not completed now or take any action, Toyota could lose money. …
My 2011 Toyota Tundra while it was being driven the engine light came on. It was driven to a nearby o' reilly's for a code check. The code was p0418 which is the air induction pump which is an emission's code. The truck then went into a limp mode while driving home on a busy city street which meant it would not accelerate over 35 MPH. This is a very dangerous situation not having the ability to go any faster due to an emission's code putting the truck into a limp mode. After researching this problem I found out that Toyota has extended the warranty for this air injection pump for the 2007-2010 Tundra models. Toyota has refused to help cover the cost for this repair even though it is a known problem on tundras. I read that the same faulty air pump which allows moisture to enter is still being used in my 2011 Tundra model. …
