Having some issues with a code I got. I started my truck and started driving down the Road and all of a sudden the check engine light and traction control off light came on at the same time. Read the code for the p0037 which shows it could be a 02 sensor but why would the traction control go off over the 02 sensor?

Trac Off light will nearly always accompany a Check Engine Light on Toyota's with Traction Control because the Traction Control System relies on the Engine Control System to be working properly.
