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…

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.

Based on research and discussion with dealer it is a known issue on the 2012 tacoma. Cost to repair i was $1484.14.…

The codes refer to "secondary air injection system switching valve…

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. *tr

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…

The check engine light and trac off lights came on. The vehicle lost power and nearly did not make it up a hill. Codes were read at a local auto parts store indicating p2440 & p2442. Took it to the toyota dealer who confirmed the codes and indicated the secondary air injection valves were burned out and stuck open, requiring replacement. The parts were replaced at a significant cost to me. An internet search…

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.

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

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!

My check engine light came on and my vehicle entered "limp mode," which keeps the car under about 35mph and prevents it from accelerating quickly. The cel read as a secondary air intake system problem (p2440 and p2442). Judging by the multitude of similar complaints i have found, this is a systemic problem that toyota refuses to rectify for tacomas but has already admitted to for tundras. This is a serious danger to…

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…

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…
