2012 Toyota Tundra Electronic stability control Problems

“Secondary air injection pump and secondary air injection switching value causing check engine and trac control lights to come on. I was told by the dealer that the same piece and design was recalled on the 2011 but not the 2012 Tundra. It comes on and off but when it is on it feels like that there is a limp mode making it difficult to get up to speed on the highway. The steering feels different which I think is the traction control.”

“I was merging into traffic on to mass 93 highway when my check engine light, trac off light and blinking 4 loe came on. The engine went into limp mode greatly reducing my power and I lost control and. I had to pull off the lane. I was able to make it to the next exit and get to a mechanics shop. They hooked up a analysis computer and came back with maintenance code p2432, secondary air pumps and secondary air pump valves. I found out that this has been an ongoing issue with Toyota tundras going back to 2007 models. …”

“I was coming off an entrance ramp merging into traffic on to a 4 lane highway when my check engine light, trac off light and blinking 4 loe came on. The engine went into limp mode greatly reducing my power and it felt like my steering control got loose. I had to pull off the road to keep from being run over by faster traffic. I was able to make it to the next off ramp and get to a mechanics shop. They hooked up a analysis computer and came back with maintenance code p2432, secondary air pumps and secondary air pump valves. …”

“My 2012 Toyota Tundra is equipped with Toyota's vehicle stability control (vsc). One of the features of the vsc is when the computer perceives a loss of traction, the computer (without the driver's consent) attempts to correct the loss of traction by braking and/or engaging one or both of the front tires. In november of 2016, the vsc on my Tundra (with only 43k miles) began to fail and instead of becoming inoperable and doing nothing, the vsc attempts to engage the front tire(s) during routine turning movements. …”

“Truck in limp mode. Would not exceed 40mph. Vehicle limped home and towed to dealer. Rodents had chewed electrical wires per Toyota dealer. Upon investigation Toyota began using soy-based wiring in their vehicles instead of petroleum-based and didn't notify their customers. Soy-based products in vehicles have been known to attract rodents versus petroleum based products. My 2012 Tundra was still under warranty and Toyota denied said warranty because it wasn't a failure of their parts. The vehicle would not accelerate properly or steer properly because the traction control and ECM had failed. …”
