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 the interstate and if this is a common problem why would y'all put a cutoff on the problem. Why is this not a recall. I bought my truck 2nd hand so I had no idea of this problem.

'takata recall' secondary air injection pump secondary air switching valves limp mode don't go over 40 crude controls doesn't work
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 avoid unfortunate accidents or death due to a known issue.
The secondary air injection system went out
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 truck. There are dozens of reports of vehicles failing to accelerate, which is obviously a cause for concern, and the $2000 recommended fix is being done with the same improperly engineered parts.
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 toyota tundra as well and a tsb has been issued to fix this problem but not for the tacoma. I have noted that my power has diminished since the lights came on (3 days). I checked with my toyota dealer and they say they have no history of this happening. Tacoma owners say this issue is well known and toyota is failing to address a fix. The loss of power can occur anytime and if it happens on a busy interstate or highway can result in accidents.
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 warranty on this injection system
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 vehicle to a service store to read the error codes. The vehicle showed p2440 p2442 error codes indicating secondary air injection failures. Apparently, the vehicle went into limp mode upon throwing these codes which limits speed and engine RPM. This almost caused a huge accident and put me into a a very dangerous situation. Additionally upon researching these issues, it seems this is a well documented issue caused by manufacturing defects isolated to the 2012 model year. Apparently, the system is defective in multiple ways. First, a piece of foam is inside the secondary air pump which degrades and is sucked into the fan which not only causes stoppage and burning out the fan motor but also allows for stinky residue and debris to enter the valves causing them to jam open or closed. Additionally, the system allows moisture to be sucked into the valves adding to corrosion and degradation of the valves leading to them to be stuck. This is a roughly 1500.00-2000.00 repair. It is a quite frequent problem with this model yet is not covered under recall or service bulletin. Toyota has acknowledged the issue yet not taken any action. Additionally, they have had similar problems with the tundra/sequoia and offered remedy to owners via extended warranty. This is not only a quality control issue but more importantly a severe safety issue with the automatic reduction to a slow speed in fast heavy traffic.
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 first 20-30 minutes of operation. The accelerator is not linked directly to the engine through a cable but is a drive by wire. I have maintained my tacoma meticulously since purchase including tune ups, oil changes, etc. I have cleaned the mass air flow sensor with no change. The problem still persists. It is very dangerous to be in the middle of an intersection with a vehicle that has lost power.
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.
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. Toyota issued a tsb and extended the warranty to 150k for the tundra but not the tacoma. Same parts! My tacoma was in motion when suddenly lost power. This is a safety issue. Check out carcomplaints.com
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 don't believe that this should effect the performance of the engine in this manner. This seems more like a software induced failure, which, in this case, caused a potentially dangerous situation. After some back and forth toyota agreed to refund me 1/2 of the $2500 that I was charged for the repair. Upon searching the internet, I found dozens of instances of this failure on 2012 tacoma's with similar mileage.
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 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 paying thousands in repairs for something that should be covered under warranty.
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 the poor design of the air-pump/valve system that prematurely failed causing the reduced power mode.
While driving on the freeway my vehicle lost partial power to the engine. I took it to the service center and they ran a diagnostic saying that I have a "failed engine air system pump and valve." it was very dangerous loosing control of the speed of the vehicle on the freeway.
Check engine light on, trac off light on, engine power weak
2012 tacoma with 24k miles. Check engine light and trc light came on with truck in limp mode when I started it to go to work. Codes p0412 p2433 p2438 p2442. Toyota wont cover this and its a defect in many many 2012 tacomas.
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 it. This occurred on my way to work this morning while getting on the freeway, and was quite scary to not be able to go over 40mph on a bay area freeway with cars honking and flying past me.
The trac off and check engine lights came on yesterday and I was unable to accelerate over 40mph. I ran a diagnotics test on it and it came back p2440 and p2442 which is the secondary air injection system failure. One of the valves is stuck open.
Secondary air injection valve stuck open causing truck to enter "limp-mode" while commuting on congested freeway system. This presented a safety hazard to myself and my family trying to merge off the freeway through traffic without any power.
Secondary air valve sticks causing loss of power,,emission system while driving and stays on.
2012 toyota tacoma w 47k miles 4 yrs old. Bought brand new from toyota. I was driving the vehicle to work and check engine light and trac off both came on. Attempted to accelerate up a hill over a bridge and could not go beyond 20 MPH with accelerator all the way down!. Vehicles speeding up on me, pulled off into emergency lane. Vehicle towed and brought to dealership where they told me a 'bank 1 secondary air injection switching valve' needs to be replaced at about $900. Not covered under warranty or a recall. Research on internet shows that this is a common and dangerous problem for this year make and model. Toyota cc called with report filed. Something needs to be done before there is a serious injury or mortality due to the vehicle not being able to accelerate in a vulnerable position.
Check engine and trac off indicator lights came in, and vehicle went into fail code mode also known as"limp mode" while driving down a town road. Vehicle was unable to accelerate above 40 MPH. Managed to get vehicle to dealership, was told the problem was a "secondary air pump and valve". Vehicle has 56,700 miles on it. Toyota was contacted and a complaint was filed, but they would not acknowledge a fault in the part in this model vehicle. Toyota tundras have had the same issue and toyota provided a fix for this model. When asked if the replacement part would fail in 50,000 miles I was told that the new part was "updated" so it shouldn't have the same issue. Why did toyota allegedly update the replacement part if there was no faults in the original part?
Vehicle lost power while on the highway, immediately reduced speed to around 40 MPH. The "trac off" indicator light came on and the truck went into "limp mode", so I was able to take the next exit and I took it to the auto part store for a code reader. P2440/ p2442 came up in error, secondary air injection system stuck open. This was an 800$ part from the dealership and I did the work.. Toyota tacoma 4x4 2012 sr5 v6 4.0l 59,965 miles
Secondary air injection system failure. If you look in line it is an epidemic with 2012 around 50,000 miles. 2000 $ repair. They don't cover. Lost power at 75 on the highway and almost got killed.
Replacement air injection valves and pumps for secondary emissions control system. Toyota wants 2200 for an issue they are aware of and have already released service bulletins for on the tundra and sequoias. Engine codes p2442 and p2446. When the codes are thrown the car is put into limp mode and decelerates to 35 MPH, even though this is a non-essential emissions system.
Vehicle stumbled and engine almost died while making a turn in front of incoming traffic with my one year old daughter in the truck. Mil on with code p2442 reported, secondary air injection malfunction. This 2012 tacoma is toyota certified with 34,216 miles, spoke with multiple toyota representatives and all have stated this is not a warrantied item. This malfunction is common on other toyota trucks which have extended warranties on the same emission component in question. This problem is both a safety hazard and an emissions hazard. It needs to be addressed.
Secondary air injection system truck would not accelerate and lost power. I've noticed it has done this since new. I now have 37,000 miles on it and have received messages check engine light and trac off messages. This is very dangerous as you have no engine power when entering into traffic. The truck will not go over 35 miles an hour and takes for ever to gain speed.
