On my 2012 tacoma the code p2440 and p2442 which represent a stuck open valve in the secondary air injection system. Upon my research into this issue on forums I have learned this is a common problem with the toyota systems particularly the 2012 tacoma. The cost of the part is about 400 to 500 dollars for the valves and another 500 dollars for the secondary air injection pump. The failure will place the vehicle into a limp mode and has to be fixed in order to the truck to keep on good working condition. It seems like this error has affected many tacoma owners.

Today leaving work my truck went into complete limp mode. Turned around and thankfully I work at a dealership not a toyota one though. I got the codes that popped up checked and it was the codes for the air injection pump and flaps. I called toyota and they said this is common in the my truck and I am right outside my coverage for it. It ends at 150,000 and I have 163. I have to drive this truck back and forth on the interstate and if this is a common problem why would y'all put a cutoff on the problem. Why is this not a recall. I bought my truck 2nd hand so I had no idea of this problem.

While on a road trip I had my check engine light come on while on the highway due to defective secondary injection valves being stuck closed/open. The codes I had for this issue is p2440 and p2442. In my case this issue made my truck go into limp mode which is often a loss of power in the engine and sometimes a restriction in one's ability to shift the truck. Luckily the highway was not busy at the time this happened, but if it were I would believe that it would be a very unsafe thing to happen going 70 MPH. The parts do have an extended warranty until 2022 if I remember right, but it seems like toyota is not interested in recalling these parts even after they have known for many years that these parts are defective. I have done quite a bit of research and found issues with these parts going back to 2013.

The check eng & trac off light came on while I was on the interstate and almost got struck from the vehicle behind me. My truck went into limp mode & slowed down to 2500 rpms & wouldn't go any faster than 25 MPH!! This is a hazard as I have read other complaints about this happening to others, it is a known issue to toyota, they have repaired the tundra's but so far am not showing any recall on the tacoma's. Error p2442 secondary air injector failure. This is the 2nd time this has happened to me. Scary! Please beware 2012 tacoma owners! Merry christmas to me! $2000 repair!

Toyota has a known issue of the secondary air injection switching valve that is faulty that causes the 2012 tacoma to go into "limp mode" expectantly. I was getting on the freeway and the truck cut out down to 25 MPH while traffic was rapidly approaching almost causing an accident. The engine codes shown are the typical p2440 and p2442 and has been reported numerous times. Please prompt toyota to recall this part to avoid unfortunate accidents or death due to a known issue.

75k miles. Cel light and trac off lights come on, truck goes into limp mode and will not accelerate past 2500 rpms, and will not reach speeds above 35 MPH. Very very dangerous and endangers not only the trucks drivers, but other drivers on the road. This is due to a faulty diverter valve that is a known issue that toyota has issued recalls on for other models with the same problem.

Secondary air pump and switching valves failed on the highway with only 62,000 miles. Truck forced into limp mode and I was not able to travel over 20mph. The truck had a check engine light and trac control light appear. Toyota attempted to charge me over $2100 to fix. After reading about the error codes this is a common problem for all 2012 tacoma owners and toyota warranty refuses to cover any of the cost or recall the part (the same issue on toyota tundras was recalled).
