2016 Tundra check engine light with traction control off warning

Update:
Check engine code was PO32D Knock sensor 3 circuit high bank 1. I can't believe a knock sensor would be bad at 17,000 miles or that it would have anything to do with traction control. I hope someone out there has a better answer.

 

Check the wiring to knock sensor to verify the voltage. I don’t know the actual numbers and you should be able to find them through some researches on internet.

From my experience, the traction control light for Toyota/Lexus came on rather frequently. My parents’ 07 Lexus RX350 once threw check engine light because one of the O2 sensors went bad, the traction control light also came on. Once I replaced the sensor, everything was fine and both lights are gone.

Good luck!
