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 to replace the same parts that have been identified in the Tundra 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 Tacoma will not cover beyond 3yrs/35K miles. Tundra have Tundra 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.

Tacoma

  • 47,800 miles
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.

Tacoma

  • 60,200 miles
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 Tacoma. Toyota extended a recall on the Tundra's because of this part, but not the Tacoma. 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.

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.

Tacoma

  • 56,670 miles
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 Tundra 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

Tacoma

  • 62,000 miles
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.

Tacoma

  • 34,216 miles
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.

Tacoma

  • 37,000 miles
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.

Dec 202016

Tacoma 4WD 6-cyl

  • 80,000 miles
Driving on the street to work one morning, the trac off and check engine lights both suddenly appeared. I then noticed that my truck was not able to accelerate past ~40 mph. Going uphill, my truck was limited to only ~20 mph. My truck went into this "safe mode." I connected an obd device and the came up with the following two codes: P2440 and P2442. The codes refer to "secondary air injection system switching valve stuck open" for banks 1 and 2, respectively. I did some further research on the codes, and it turns out this is a common issue on 2012 Tacoma. Apparently, the valve for the secondary air injection system is stuck open due to moisture and/or carb build up. I believe this is a design/engineering issue. Part replacement costs ~$480 for each valve assembly. Labor can range anywhere between $200-$500. If this is a known issue that is common to a lot of 2012 Tacoma, then I believe Toyota should be proactive such as releasing an official recall or even implement some type of reimbursement. Note that my truck has ~80,000 miles on it. As an owner, I shouldn't suffer from an engineering design flaw and I shouldn't be financially responsible to repair/fix the issue. Any assistance would be helpful. Thank you and happy holidays!
