Check engine light secondary air intake this was a recall in 2007-10 years but is also been a common problem in earlier models. This is a very expensive repair.
Check engine light came on and the truck lost power. The engine revved like it was trying to go, but had no more forward momentum. The speed at the time of the incident was 50mph. Hooked up the computer and the error code read that it is the air switching valve. Error codes p-1442, switching valves are stuck closed, #2 in bank 1 and #2 in bank 2 of the secondary air inspection system. Same issue on 2007-10 Tundra and was recalled due to defect. My truck has the same issue, has under 150,000 miles, and has been very well maintained. Told by Toyota that it is not a recall at this time and if there is one in the future, they will reimburse us our costs. Driving down a two lane highway with 18 wheelers behind you and losing power, going 65-70mph, is going to cause a wreck. I don't know how Toyota would reimburse me my husband.
The truck was brand new and only had 4,500 miles on it when the check engine light came on and the truck started acting funny. Toyota said they were not going to fix it and I was never given a replacement under lemon law when this happened. I had just got the truck in October 2005 and in December 2005 it started acting up. I am a trained mechanic and I know this should not happen to a new vehicle. I want Toyota to refund me the money I put down on the truck, which is around 8 grand.
