While driving the check engine light came on and I lost propulsion power resulting in vehicle slowing down and almost creating an accident from behind. I had the vehicle checked via a obd2 code checker which resulted in code p2442. After verifying code, it looks as if it is a faulty air intake. Looking through several sources on the internet, it seems to be a very common problem that Toyota is refusing to acknowledge or repair. Please take this issue into consideration and help the consumer. Fuel propulsion system I purchased my 2011 Tundra quarter end 2011. It has less than 100k miles and is well maintained by the dealer. Late may 2017 e light came on and I took the vehicle to the dealer to have this checked. I learned that I had an issue with the secondary air injection system. The estimated cost of the repair was quoted at $3,000.
