    My check engine light came on and i had no acceleration beyond 20 mph. I took it for a diagnosis at auto zone and they told me it was codes ,2450 and 2442, secondary air valves stuck open. I am stuck in an unfamiliar city and no mechanics with time to fix it, to say nothing of me not having the funds to pay for the repair. The light came on when i was turning a corner on a hill. I understand this has become a very…

    About 2 weeks ago my truck was hesitating and my check engine/off trac light was on. The car would not go above 40mph on city streets or highway. I went to a toyota dealer in puerto rico, they said the codes were p0052, p0456, p2140, p2442 secondary air injection system is bad and would cost $2,458.08 for repairs. I don't know if it is covered by any warranty. It is a 2012 toyota tacoma pre-runner.

    Today leaving work my truck went into complete limp mode. Turned around and thankfully i work at a dealership not a toyota one though. I got the codes that popped up checked and it was the codes for the air injection pump and flaps. I called toyota and they said this is common in the my truck and i am right outside my coverage for it. It ends at 150,000 and i have 163. I have to drive this truck back and forth on…

    Toyota has a known issue of the secondary air injection switching valve that is faulty that causes the 2012 tacoma to go into "limp mode" expectantly. I was getting on the freeway and the truck cut out down to 25 mph while traffic was rapidly approaching almost causing an accident. The engine codes shown are the typical p2440 and p2442 and has been reported numerous times. Please prompt toyota to recall this part to…

    Secondary air injector failure. Valves stuck open. Check engine codes p2442 and p2440. Vehicle in motion driving 70 mph on the interstate. Just bought yesterday with 47k miles. Failure causes vehicle to 'limp'. Can't exceed 2500 rpms very easily, massive loss of power.

    Cold start of the vehicle was followed by a high pitched whine and then the check engine light and 'trac off' lights illuminated. Diagnostic check revealed faulty secondary air pump and switching valve. This problem has been acknowledged by toyota for the tundra and the sequoia, but they continue to play dumb on this model year tacoma. A cursory search of the internet reveals this is a widespread problem in the 2012…

    Code p2443 valve stuck closed came up when my "trac and cel" lights came up on the dash. This happened on startup. This code is a failure of the secondary air injection switching valve stuck closed. This condition can lead to lost power when driving called a "limp mode" and is occurring on toyota tacoma"s at around the 50k mile mark as i have found on the tacoma world website. This issue has also been noted on the…

    Check engine light and trac off light came on. Truck went into "limp" mode and would only go about 35mph. Checked the error code and it was p2442 which says the secondary air injection system is failing. Truck has only 55k miles on it and has been regularly maintained by toyota dealerships every 6 months / 5k miles. Dealership has said it will be $2023 to replace the system. There should be a recall or extended…

    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…

    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…

    Check engine light on, trac off light on, engine power weak check engine code- p2441. This has been a common issue with toyota suvs, and trucks! Car is put into limp mode. Extended warranty on tundra with same part problem. Not tacoma. Shameful and dangerous for tacoma owners.

    Secondary air pump failed at 47,000 miles, shortly after warranty expired. It failed as i was pulling out onto a major fast-moving highway and promptly went into "limp" mode, limiting acceleration. It took over a half mile to get the vehicle to 40 mph. Meanwhile, vehicles behind me were braking abruptly to avoid colliding with me. As i understand it the secondary air pump is part of the emission control system and i…

    Secondary air injection error codes p2440, p2441,p2442. Loss of power due to air injector stuck. Vehicle will not accelerate beyond 20-30 mph. This is an emmsisions requirement but warranties on tacomas will not cover beyond 3yrs/35k miles. Tundras have tundras have same known issues and toyota incrwased warranty to 10 yrs/150k miles. Sudden loss of power is also a safety issue while driving on highways. Owners are…

    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.

    Like many others, my 2012 tacoma suddenly lost power on the hiway. Refused to go above 40 or so mph. Other cars had to slam on brakes to avoid me. Took it to the dealer and they wanted nearly $2000.00 to replace the same parts that have been identified in the tundras as being defective. Secondary air injection stuck open. The codes are p2440 and p2442. This is a safety hazard as the vehicle suddenly loses power.…

    Emissions air pump valve went out with 60,200 miles on the truck. The truck is bone stock and has been very well maintained. After research its seems that numerous people are having issues with this same exact part on the 2012 tacomas. Toyota extended a recall on the tundra's because of this part, but not the tacomas. The truck is currently in limp mode and will not go past 40mph, and the dealer wants $1,075 to fix…
