p1135 & No VSC TRAC

[zooroadbaja]

My T4R check engine light just came on with the P1135 code, which I believe is the front O2. But I was more curious why the VSC & TRAC get turned off. What does the O2 have to do with the VSC & TRAC? Or does it always turn it off when it throws a code?

VSC & trac Always turn on (the light) when CEL illuminates. It's a Yota thing.

Weird, I wonder why. Who knew you could do the andymod by just leaving the gas cap loose :eyebrows:
