Recently i was driving my 2012 toyota tacoma on the highway at a sustained speed of 70 mph. A check engine light came on and my car instantly dropped in speed to less than 40 mph while in fast moving traffic. I was almost rear ended by a large truck and was forced to cross multiple lanes of traffic to get to the berm and ascertain the situation. As i could find no issues upon inspection, i precariously drove the…

This happened on i-90 in heavy traffic causing other motorists to apply…

My 2012 tacoma is throwing lights on for a new secondary air injector valve , parts p2440 and p2442. The toyota mechanic said this is a common problem with these over the past few years as the 2012's hold moisture after shut down and the valves break down. I see this is a common problem online and a very expensive fix for us all. This should be covered fix, just because it doesn't cause in imminent health hazard…

I was pulling out on to the highway and my truck failed to exceed 30 mph with oncoming traffic which nearly caused an accident. Upon inspection by my toyota dealership, they explained that my secondary air injection valves were stuck open (p2440, p2442) which caused the truck to lose all power. I was then told that since i am no longer under warranty (my truck is only 5 years old with 48,000 miles on it) that toyota…

Error code p2442 secondary air injection valve stuck open. Truck immediately goes into "limp' mode and will not accelerate over 20mph. Extremely unsafe to have the vehicle decelerate on a highway for a known issue that has prompted warranty extensions on toyota tundra's.

I start up the truck and pull out in to the street. Whether at an intersection or making a turn, i push on the accelerator and nothing happens. The rpms don't increase, engine makes no sound - and i am left sitting in the middle of the road. I push the accelerator to the floor and eventually the engine comes to life and the truck moves forward. Happens more often than not when the vehicle is "cold" - within the…

The truck had a check engine light and trac control light appear. Toyota attempted to charge me over $2100 to fix.

While commuting to work the engine light and traction control light came on, causing my truck to slow down, very slow. It would not let me accelerate and disabled my progress to around 2000 rpms. This could have been a very serious or a dangerous situation especially if i was towing a load or in a major traffic situation. Codes - 2440 and 2442 were the causes of this scary account.

At start up "check engine" and "trac off" lights were on. Truck had no acceleration and transmission would not shift.

During research, i discovered numerous other owners of 2012 tacoma's complaing about the same issue. Some even lost power while driving. Also, the…

Secondary air injection system (p2442). This hardware defect has been a recall for tundra but not for tacoma. The part is defective on most 2012 tacoma and very expensive to replace. There are safety issue as the vehicle unable to accelerate, but only able to limp. There are many discussions about this issue but toyota has not done anything about this.

Vehicle was in motion on rainy, wet highway when check engine light went on and traction control was shut off. The secondary air injection switching valve is apparently stuck closed, which for some reason shuts off the traction control. It is my understanding from speaking with other tacoma and tundra owners that had the valves gotten stuck open, the vehicle goes into "limp mode" which automatically decreases speed…

Failure of the secondary air injection pump and valve emission system prompted engine to run in a reduced power mode, and this occurred on a on a relatively new vehicle with below average mileage. While setting may protect engine, this created an unsafe driving environment for vehicle within fast moving traffic. My compliant is not related to the reduced driving mode that may have protected the engine, but rather…

My truck's check engine light and trac off light came on and i took it to my local repair shop. The manager told me that after the level 1 diagnostic, a p2442 error code appeared (switching valve stuck). The valves, and air pump are part of the secondary air injection system which diverts some exhaust back into the engine to reduce emissions output. As part of the truck's emergency system, the truck limited the…

Secondary air injection valve quit working and put my truck into a 'limp mode.' during this time my speed was cut no more than 40 m.p.h. I was merging onto the highway at the time and it created a very unsafe condition. I started researching the issue and saw a ton of other people had the exact same issue. I'm sure toyota knew about it as well, because the mechanic at the dealership did. Why didn't they put out an…

2012 toyota tacoma. The vehicle has codes p2440, p2441, p2442 relating to the secondary air injection system (sais) valves being stuck open/closed. This appears to be a common problem with 2012 tacoma vehicles and several years for tundra vehicles. For the tundra, toyota instituted a customer support program and extended the warranty coverage for the sais. With the vehicle having only 47,391 miles, it is outrageous…
