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. I took the car to the dealership and diagnostic codes p2440 and p2442 were detected. Dealer had to replace the air injection system bank 1 and bank 2. During research, I discovered numerous other owners of 2012 tacoma's complaing about the same issue. Some even lost power while driving. Also, the tundra apparently had a similar issue being reported

I was leaving work and pulling onto the highway when I noticed my check engine light came on, as well as the trac off light. I went to pull into traffic and immediately realized that whatever was wrong put my truck into limp mode and had a 2500 RPM limit. This was a 60 MPH highway and I couldn't go more than 35 MPH. The traffic coming was immediately upon me and I had to pull over and put on my hazard lights as these vehicles had to slam on their brakes, honk, and swerve around me. I brought it into the dealership and they read code p2442. Which is for a stuck secondary air injection valve. They found water in the valves and they had to be replaced. Doing some research I found this is a very common issue in 2nd gen tacomas, mostly the 2012. This a very well known issue, especially to toyota, and they have so far done nothing about it. This LED to a very dangerous near crash incident which I then had to pay over 1200 dollars to fix. This is completely unacceptable. Toyota must at least take ownership of their poorly designed parts and cover the replacement of these valves and pumps. This is happening all over the country on a consistent and persistent basis. Please make toyota address this, their customers deserve so much better.

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 to 20mph. Obviously, either of these occurrences are particularly unsafe in rainy and wet conditions, and the decrease in speed is unsafe during any highway traveling. This is apparently a big enough issue on the tundra models for toyota to extend the warranty to 150,000mi, yet they have done nothing for the tacomas which have an identical system and parts.

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.

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 engine operation parameters to about 2000rpm, and about 40mph maximum. Express oil change and tire engineers quoted the parts at around $1500, not including labor. The day of diagnosis, the truck had 72,952 miles and was purchased nov. 2011. Currently unable to safely drive my truck in normal traffic. Facing a nearly $2k bill, I decided to do some digging into emissions warranty information and found that those parts were not going to be covered by the 8yr/80,000 mile federal emission control warranty as outlined in my warranty and maintenance guide, even though these are a critical part of the system. While online, I read several posts on tacomaworld.com where several others were having the same issues. What was more concerning was that this very same issue was very common in toyota tundra not long ago and the manufacturer extended their warranties to cover the costs because it would appear to be a manufacturer defect. Now, the very same thing is happening with tacoma but the extended warranty has not been extended to my truck. The service lights have since come back on and the truck is not drivable, I have yet to get a hold of toyota but because of the holiday, I will have to wait until the morning but not expecting much. Who will pay for my rental car while I'm paying this bill?

As I went from side road to main road, truck would not accelerate to full speed even with foot on the pedal, indicators trac off and check engine were lit. Went to mechanic and error codes p2440 and p2442 indicated malfunction in secondary air injection system. Was told new air pump and diverter valve required at cost of $2k. Truck has less than 30k on it,but is 5 years old. Going into limp mode is dangerous as the main street is 55mph. Toyota states tundras have same issue that is now covered by 10 year/150k warranty, but nothing for tacoma owners. So I am quite angry with that as well. Have read online that many other owners are having same issues. Toyota should recall these defective pumps and valves in addition to disabling the limp mode as it is very dangerous.

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 alert or recall??

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 that the sais would have issues or failures especially being a toyota. Since the truck is in limp mode and not safe to drive, it will have to be towed to a dealership. Between this issue and a noise and pulling periodically from the front differential/drivetrain, we are very disappointed in this vehicle.

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.

My 2012 toyota tacoma first started throwing a p2442 error code and I had a mechanic clear it twice. Now it is throwing a p2440 and p2442 error code. This is the secondary air injection system valve assembly. Both bank 1 and bank 2 valves are stuck open. I called toyota corporate (1‑800‑331‑4331) and filed a complaint after seeing all of the other 2012's with the same problem. They just want me to get it to a toyota dealership to read the code and then go from there. Unfortunately I don't live near a dealership and they want to charge me for a diagnostic test that my local mechanic just performed. The truck is in limp mode with the check engine and trac off lights illuminated.

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.

Cel and trac off lights came on and truck went into limp mode. I was only able to drive 25-35mph in limp mode. Took 2012 toyota tacoma to local mechanic and the trouble code was p2442, secondary air injection system bank 2 valve stuck open. Contacted toyota dealer but no help even though toyota corporate is aware of the problem on 2012 toyota tacomas as well as other models.

Bought truck new in 2012 and maintained 100% recommended maintenance at dealer. At 64,500 mileage, check engine light came on while driving, and we drove truck straight to dealer service garage. Dealer determined secondary air injection pump had contaminated with water, resulting in rust in system (valves also). Replaced pump and valve assembly and gasket. Service advisor said the same parts were used and recalled in response to reports of air induction pump assemblies and/or air injection switching valves issues on their 2007-2010 tundra and 2008-2010 sequoia models, toyota has decided to increase its warranty on these parts and is even offering a reimbursement if you already had this issue fixed. Tacoma's need to be included in the recall reimbursement! When we asked about how to prevent future issues, service tech informed us the part has been "re-designed" to prevent the problem from re-occurring. Total bill from dealer was $1968.29. This vehicle has never been off road, never been in flood conditions, and is a commuter vehicle on paved roads.

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.

4.0l v6, dcsb, at, or package, 4x4, 41.5k miles, cel on, tcl on, limp mode on, codes p2440 p2442. References a secondary air pump valve issue. Truck was started in the morning, reversed out of driveway, cel, tcl, and limp mode activated when put into drive. Unable to reach safe operating speeds due to limp mode. Veh was on city street when codes triggered limp mode. Failure of poorly designed valves and system causes valves to remain stuck open allowing a larger than normal volume of exhaust fumes to recirculate to the intake through all operating ranges instead of just engine start up. Potential for engine failure and fire.

While driving on a city street the check engine light and trac off light illuminated and truck would not go over 25 MPH. Brought directly to mechanic that found diagnostic trouble code p2442 - secondary air injection system malfunction. At 61k miles this faulty part was not covered under any warranty. The part cost alone was $1321 and then add tax and labor for a total of $1709! So disgusted with toyota for not taking accountability for this faulty product.

As I read through the complaints on here, it seems most are for the same issue I have seen. As it is the biggest complaint item for 2012 tacoma on this website, and the fact that there is a recall on tundra for the same item, and that 2013 tacoma were redesigned to fix, this is clearly a known issue of a faulty part/design of the the air injection pump valve. It is unacceptable that nothing is done about this and the danger it poses. Like the others, I got a check engine light/trac off one evening when I started my truck. My truck started up fine, and I didn't notice a problem until I tried to merge onto a 60 MPH road. I tried to accelerate and merge but I almost caused a pile up as I could not accelerate beyond 35 MPH. Luckily, all I got was a bunch of honking. This is a very dangerous situation! After further research, I saw the codes p2440 and p2442 and understand it is a limp mode due to an emmisions item at startup. Before being able to fix, I had to work a shift at my second job of ski patrol in the rocky mountains. As my truck obviously couldn't make it up the canyon, I was forced to borrow another car, and all I could get was a 2 wheel drive. There was a late season storm, and because I didn't have my 4x4 truck I got stuck overnight in the mountains. I survived, but twice because of this issue I was faced into a dangerous situation. I bought a new 4x4 for the very reason to avoid dangers like these. Granted I have 65k miles now, but I don't expect a vehicle to have major problems like this. It is even worse to find out that it is a known issue and no one is doing anything about it. It is a disappointment that with a known issue toyota has not done something about this for the tacomas, but I am equally surprised that there are so many complaints and examples of dangerous situations and the federal safety agency hasn't done anything either.

Air valves in emission system went bad, was reduced to driving 35mph in heavy traffic, very unsafe. Was quoted $2500 in repairs for repairs resulting from faulty design. Reports rampant on the internet of this part failing. Tpyota fixed the issue on later model tacomas and recalled tundras with the same issue but have ignored this make/model/year.

On the way home from a recent camping trip my check engine light and trac light came on in my truck. The truck went into "limp" mode would not accelerate up a hill above 20 miles per hour. We drove to the nearest auto zone, they pulled the codes p2436 and p2442. I was able to clear the codes and make it home. I started researching this and found the secondary air switching valves to be a common failure on tacomas and tundras. I feel this part needs to be recalled and upgraded, this could be a major safety issue if the vehicle went into "limp" mode in heavy traffic or while crossing across heavy traffic. The replacement part 25710-31022 was ordered from the dealership today. I also filed a complaint with toyota customer service.

I have a 2012 toyota tacoma 4x4 sport double cab longbed with 28860 miles. I started the engine and noticed the "check engine" and "trac control" lights on in the cluster. As I was driving I noticed a lack of power it was in "limped mode". Made it to my mechanic who did a code check with reader, codes p2440 and p2442 shown which is secondary injection pump valve malfunction. The concerning aspect is that with such low milage this malfunction occurs that makes the truck go into limp mode which can be dangerous in any give situation on the highways. Toyota must really consider investigating this defect.
