Question about 2006 Toyota Sequoia
I am getting all three of these lights after I start the engine. I think I might know the cause, but will not be able to confirm until tomorrow when I go to have the codes read and cleared. Everything on the vehicle was fine until yesterday when I decided to change the oil. I put the vehicle up on ramps, drained the oil, changed the oil filter, and changed the air filter. In order to get the top of the air filter off, I unhooked the electrical connection on the top of the air filter enclosure. I re-installed the drain plug and filled the engine with new oil. When I went to start the engine to back it off the ramp, I got the abovementioned fault lights and the engine uncharacteristically stalled out. I went around and found that I had forgotten to re-connect the electrical plug at the top of the air filter. Once I re-attached it, the engine seemed to run fine, but I still had these three fault lights. My suspicion is that when the plug was disconnected, it triggered a fault and that, until the fault is reset, the lights will continue to appear. I have not tested the function of the traction control or ABS. As I said, I will be taking this into the garage tomorrow for a quick diagnosis and will update you with what I find.
The VSC TRAC and TRAC OFF lights come on everytime the CHECK ENGINE light comes on. I think you just need to get the light reset.

It was trigger by the unconnectedc sensor at the air box. go to an autozone or sinilar parts store. most have a code reader they can put on the car for free and give u a list of codes.
