P2442 on Toyota vehicles

104 owner complaints filed with NHTSA about Toyota vehicles mention P2442 (AIR System Switching Valve Stuck Open Bank 2) - across 3 models. Below is where it shows up, by model and year.

Can you drive with it? Yes, with the same caveats as its bank 1 twin - possible reduced power mode and a certain emissions test failure until repaired.

Symptoms, likely causes in order and realistic repair costs are on the main P2442 page - they do not differ much by brand. This page shows what is specific to Toyota: which models and years actually report it.

My 2012 tacoma warning light 1) engine and 2 trac off warning light came on and lost power going 65 mph on freeway and would not go over 25 mph (dangerous!). Obd-ii scanner displayed error code check p2442 indicating faulty air injection pumps and/or air switching valves. *tr2012 Toyota Tacoma · May 2020 · 91,000 mi
On my 2012 tacoma the code p2440 and p2442 which represent a stuck open valve in the secondary air injection system. Upon my research into this issue on forums I have learned this is a common problem with the toyota systems particularly the 2012 tacoma. The cost of the part is about 400 to 500 dollars for the valves and another 500 dollars for the secondary air injection pump. The failure will place the vehicle into a limp mode and has to be fixed in order to the truck to keep on good working condition. It seems like this error has affected many tacoma owners. *tr2012 Toyota Tacoma · Apr 2020 · 103,000 mi
Failure of the secondary air injection system p2440 and p2442, while the vehicle was moving onto a city street from a parking lot. When accelerating immediately there was a decrease in power and the check engine light along with the "trac off" light illuminating simultaneously. The vehicle has a now maximum speed of around 55 mph and extremely slow to accelerate being almost dangerous on busier roads. After being check out by a the dealer it was found to be the secondary air injection system which is covered by an extended warranty but parts are on back-order.2012 Toyota Tacoma · Dec 2019 · 91,500 mi
