This morning i started my car and my CEL came on and the Trac light is flashing........the only code im getting is P0116 for the coolant temp sensor....could this cause the trac light to flash.

Did you check coolant levels and they are ok?
Only time my cel and trac lights came on it was because of o2 sensors.

coolant levels are fine......Im kinda confused y the track light and cell would come on at the exact sametime and the only code I'm getting is for a coolant sensor......

Well i just purchased a new temp sensor from napa for $21 and ordered an oem from the local toyota dealer......I'm really not sure what is causing this issue nor do I know what damage not fixing it can do so I figured the napa sensor will hold me over until later next week when the oem one comes in.

im still not sure how these two lights are linked together

I have worked on some toyotas that the track light comes on with the check engine light.

hmmm thats interesting.......but why would the trac light flash?

Ok now I'm confused.....both the track light and cel r off and there are no stored codes........

Maybe your coolant sensor went wrong at the same time as your o2 sensor and that´s why it gave you that code.
I didn´t change o2 sensors yet and I have CEL and TRAC light only when it rains. The drawback is that I loose traction control when that happens.
