P2440 Toyota Tundra
Anyway it had two codes - P2440 and P2441.
P2440 toyota tundra. P2440 is a diagnostic trouble code DTC for Secondary Air Injection System Switching Valve Stuck Open Bank 1. I brought it to Lia Toyota in Wilbraham MA and they were great. In 2015 at 125k miles I had code P2442 with flashing dash lights and limp mode so Toyota fixed that under.
Told them the codes and he knew exactly what it was. I just got the p2440 code on my 08 Tundra. 2008 Tundra SR5 47L.
Called Toyota today and they wont warranty it say they only cover one fix of the system. Most auto repair shops charge between 75 and 150 per hour. After he double checked the codes said it was under warranty and they replaced the pumps and the valves for nothing.
To accelerate the activation of catalyst when warming up the engine the air injection system pumps the secondary air to the exhaust manifold by pressure. Hey everybody I have a 2007 Tundra 47. Im currently getting the codes p4012 p2432 p2433.
2007-2020 Tundra Tie Down Bed Cleat for Deck Rail Toyota PT278-0C010 - OEM 2 2999. Been very happy until this week when the dreaded P2440 code popped up with check enginetrac off limp mode. The valves tend to get stuck due to water.
This is a 2008 47 tundra. Open and close movement of the air switching. Get the P2447 code diagnosed by a professional.
