general problems of the 2012 Toyota Tacoma - part 2

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.

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.

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 pump and valve failure. Second time in 1 year.

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.

Ecl code p2442, secondary air handler, epa part but Toyota dealers won't cover under epa warranty.

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.

While driving and turning onto a highway, "check engine"and "trac off" warning lights came on as I pulled into traffic. Truck went into limp mode so I couldn't accelerate. Oncoming traffic worked around me as I turned on my hazard lights. Secondary air injection system p2440 and p2442 are the error codes associated with the valves stuck open.

2012 with only 24,900 miles and my vehicle has the same issue as the Toyota tundra issue relating to secondary air injection pump. Dealer says it's not covered. The are an awful lot of people with the same problem on their Tacoma's. It's no fair!.

Pulled onto the interstate and the truck would no accelerate. Put on my hazards and tried to avoid getting hit. Got off on the next exit. Had to go up a hill to get home and truck was struggling to maintain 20 mph. Took it to the dealer who said it was the air injection valves and that the truck had gone into limp mode because of the emissions problem. Codes were p2440, 2442. Dealer said problem is not covered by powertrain warranty and emissions warranty expired.

Code p2442: secondary air injection system switching valve stuck open bank 2. This happened on a vehicle that does not tow, drive off road, and is in warm weather climate, austin, TX. My commute to work is 5 miles, each way. Toyota says this is not covered under power train or emissions warranty. This is a $2,000 fix for a vehicle with only 59,000 miles.

Code p2440 and p2442. Air injection system valves are stuck open (related to emissions control unit) which causes the vehicle to go into 'limp' mode abrupbtly. This renders the vehicle undriveable, and can occur in the midst of driving causing serious danger to the driver and fellow drivers on the road. Toyota is unwilling to cover under any powertrain or emissions warranty. This issue is pervasive among 2012 Tacoma owners and Toyota redesigned the system as early as 2013 which implicates their knowledge of such a defect.

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.

Check engine code- p2442. This has been a common issue with Toyota suvs, and trucks!.

Secondary air injection system failure. Failure codes of p2440 and 2442 occurred during highway driving, causing vehicle to go into limp mode. The vehicle at this point was unsafe to drive due to limited throttle control. Research has shown this is a very common problem with 2012 Tacoma trucks.

Air injection system failing putting truck into limp mode (codes p2442 and p2440) an unsafe driving condition. Common low mileage problem that is not covered by either federal emissions warranty or power train warranty.

The engine check and trac off lights on when I drive on highway. The secondary air injection system failure the dealer checked, it will cost $2000 to fix it, it is only 69k miles and 5 years old vehicle. I could not accelerate the vehicle on highway and it suddenly slow down.

Truck normally starts right up, cranked it over no start. Tried it again and it started, but the "check engine" and the "trac control" lights stayed on. Tried getting on the freeway and had very little power getting on the on-ramp. Put the flashers on to prevent cars exiting the freeway @ 65 mph from crashing into me and my limping Tacoma. They also put their flashers on too. Very unsafe! limped towards home on surface streets. . . . 1 hour drive took me 2. Scanned the error codes and p2440 and p2442 came up, switches stuck open in the #1 & #2 bank. After spending $1470. 54 for parts I made the repairs. Looked @ a CO-workers 2008 Tacoma and this bad idea is not on his Tacoma. . . . . Hhhhhmmmm. He,s just lucky I guess. Please help. Very unsafe design, very expensive remedy.

Check engine and trac off light on when starting vehicle. Noticed it would not accelerate much at 20mph (limp mode?), so I pulled over and called dealer service and took for diagnosis. Luckily not in heavy traffic or busy street, just neighborhood. Dealer repaired secondary air injection pump and valves for $2,000. Indicated not a normal repair. Internet search proved otherwise as its a extensive issue with prior models of Toyota vehicles and 2012 Tacoma's.

Secondary air injection system switching valve error code p2440 and p2442 truck is now in limp mode and undriveable.

Air injection pump and diverter valve assembly failed causing vehicle to enter limp mode. Vehicle was moving at low speed from a fresh start up. Toyota has recognized thie issue on the tundra truck and extended 150k mile warranty on the part. They have not extended the same consideration on the Tacoma. Based on research and discussion with dealer it is a known issue on the 2012 Tacoma. Cost to repair I was $1484. 14.

My 2012 Toyota Tacoma check engine and traction control light came on. Truck went in limp mode, which was very unsafe. Took my truck to auto zone to have the codes read. My truck code was p2442. Air injection system switch valve stuck open. This is a known issue to Toyota tundra trucks but not for the Tacoma.

Engine code p2442 & p2440: secondary air injection system switching valve bank 2. Truck only has 40,000 miles on it. Dealer what $1800. 00 to make repairs. Toyota has a problem with the part and they need to fix it. Nothing like having numerous failures and leaving the customer to pay for the poor engineered part.

When I was leaving work the other night my 2012 Tacoma went into limp mode and presented the cel and trac off lights on the dash. After reviewing the many blogs on the subject and taking the vehicle to the mechanics, I have found out that the secondary air valve is likely stuck in the open position. The mechanic has quoted me a price of $1,142 ($780 for the part) to replace the whole system (valve not sold separately). I understand that this is a common problem with tundras/sequoias and 2012 tacos. However, only the tundras are under any type of warranty. I bought a Tacoma because the last two Toyota's have run 300k miles + with regular maintenance. This type of expensive repair due to poor engineering is ludicrous and should be a warranty issue. I guess Toyota wants to be terrible like everyone else. Great.

Secondary air intake system failed during start up. The vehicle is drivable but dangerous cel is on and computer limits the vehicles power. This is related to emissions. The vehicle was 8 days out of warranty with 39500k miles. This system has been a problem in other Toyota vehicles including the 2012 v6 Tacoma. Cost of repair estimated at $1950. 00.

Secondary air injection valve stuck open causing limp mode. Happened near very dangerous intersection and lost all power in truck. As others have stated, truck only has 50k miles and required a $500+ repair (part only) for a component of the emission system which is only used on startup and includes a warranty of only 2 years.

Engine/all power is lost when engine has reached a certain rpm. Code reader states "crankshaft position sensor "a" circuit malfunction".

Check engine and trac off lights came on. Vehicle acceleration became very sluggish. I felt the vehicle became a safety hazard as it had almost no acceleration . Merging into traffic became dangerous because of lack of acceleration. Had local shop check truck and error codes returned were p2440 and p2442 which they said indicated secondary air injector pump needs to be replaced. Est charge about $2000!.

I got the engine lights on in the morning starting the truck on Nov 3, and truck went into limp mode. Got it home and let it sit for a bit and then it seemed to be okay accelerating but the engine lights were still on. Took it to Toyota and was reading the dreaded p2442 secondary air injection system code. They cleared the code and drove it around; cleared again they deemed it okay and charged me $60 for the code read. Leave to drive to work again this morning and bam, the lights back on and the thing is back into limp mode with barely any power to the engine. Had to drive this truck in this unsafe condition back to my house. I read so much online about how many people are affected with this same defective part and Toyota quoted me $2300 cad + 13% tax to fix it and replace the secondary air injection pump/valve. Not covered under any warranty nor my extra care protection plan I paid for.

2012 with 78,000 miles, threw codes p2440, p2442. Same as every other Tacoma owner in this year range. Bad valves and pump on the secondary air injection unit. Cost to repair around 1,000 dollars doing the work myself. Very disappointed as this is my third Tacoma and had planned on keeping this one for a long time.

Driving vehicle and all of a sudden engine looses power. Truck did not die and would slowly accelerate. I had traffic behind me honking and cutting me off until I could get to a pull off spot. I had the vehicle towed to a mechanic and discovered the secondary air pump and valves were the cause causing the lots of acceleration. This is a very dangerous and known issue for Toyota owners after researching. I do have repair receipt which is very costly.

Tacoma went in "limp mode" engine light and trac off light illuminated; cause the car to be extremely under power. Vehicle extremely under power causing to be dangerous in traffic. Code p2442 secondary injection system failure; common to other Toyota vehicles including tundra's. Toyota acted resumable with tundra's with extending warranty repairing but at this time refuses to repair known failures in Tacoma's.

Secondary air injection switching valve failure stuck in open position causing limp mode in the truck. Truck is not able to get to speed above 40 mph. This happened as I was pulling out of my neighborhood onto a state route with speed limit of 55 mph and cars going way faster than that. This could pose a danger if situations where speed it required to get out of the way of another car. Truck only has 57k miles on it. This is a supplemental emissions system and should not cause the truck to be useless if fail.

57,000 miles on truck went into limp mode, p2440 and p2442 code showed secondary air injection valve dealer quoted $2000, said they wouldn't cover anything.
