    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.

    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.

    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.

    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…

    Secondary air injection system: started the vehicle and check engine light came on. Obd read p2440/p2442. While driving uphill on a very busy highway, the vehicle loss power and would not go faster than 20mph and the rpm's rammed up. After some some research found out this is a common problem with the tacoma in which toyota was aware of.

    The air injection pump went out and had to be replaced, and there is only 18,200 miles on the vehicle. The check engine light came on while driving, and i was able to drive the vehicle to the dealership before "safe mode" kicked in. Toyota was able to replace the defective part. I understand from reading on the internet that this is turning out to be a common problem for this vehicle, and wish to add my experience…

    My 2012 tacoma with 45,000 miles got a check engine light and "trac off" light when i started it to go home. I was merging onto the interstate and unable to go above 40 mph. This was obviously not safe so i exited and took it to a dealer. They cited trouble codes p2440 and p2442 and said they needed to replace secondary air injection valve (pn 25710-31022) for a total cost of $940! According to forums and the…

    My 2012 toyota tacoma prerunner 2wd has 54,640 miles. I just got a check engine light and "trac off" light yesterday. My truck would accelerate to just 25 mph when merging onto the interstate and top speed was around 50 mph. This is a serious safety issue and toyota will not cover this known problem under the standard 3 year 36,000 mile warranty. Autozone ran the diagnostic scan and came up with trouble codes p2440…

    I took my 2012 tacoma into service today with a trac off and check engine light on. I was told that the secondary air injection switching valve needed replaced at the tune of $1300. I see that many others have had this issue and with 37k miles, i find it unreal that this isn't covered under the powertrain warranty.

    Only 49,000 miles on my $32,000 truck and like many other owners of 2012 tacomas i have the check engine light come on with the trac off light and giving the diagnostic code of p2442 secondary air injection switching valve. This is clearly a emissions and manufacturing problem with this year and toyota should have to foot the bill instead of charging us $2,100 for a fix a a practically new expensive truck. The air…

    The secondary air injection systems seems to fail quite frequently on these 2012 tacomas with little to no help from toyota to take care of this issue as a recall. These are known to fail right after your out of warranty and to charge it's loyal customers over $1000 for a part that should not fail or a part that should be covered is absurd. I have been a loyal toyota customer my whole life but the issues of the…

Drove to toyota dealer who said this was third tacoma this week with faulty second air fuel injector. No recall yet, but 3 weeks for back order of part. 43 others before my part request. Same part on recall for tundra model. Safety was compromised on…

    My tacoma tends to surge forward when it is stopped. I do not think it has anything to do with the air conditioner being on.i had the a/c off the first time. If someone isn't on the brake firmly they may tap the vehicle in front of them. *tr
