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 ([redacted]) 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…

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…

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…

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…

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…

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…

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…

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…

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…
