Flashing VSC OFF, VSC TRAC and Check engine

[UGAbulldawg]

Like the title says I came out this morning and it was showing these codes. Did some research and the problem seems to be the oxygen sensor. Is this a hard part to replace or does it need to be replaced right away?

Well in general an oxygen sensor is not difficult to replace but depending on the location it might be a squeeze. But you should replace it as soon as possible since with any check engine light the ecm disables the traction control, anit-skid ect... and the vehicle becomes more dangerous to drive.

I looked it up in alldata and it pays 2 hours per side on the fronts and .5 hours per side for the rears so hopefully it is a rear o2 sensor you are needing seeing as they are easy to get to.

Thanks for your help. I'll look into it a little more and see if i can tackle this on my own.

We just had this happen in my wife's O7 sequoia... It ended up being the gas cap... The seal failed and need to be replaced... So it could possibly be the same thing... good luck

Mine was similar, replaced the gas cap and it went away for about a year. This time it threw a code for the bank 2 O2 sensor so I replaced it. $85 for a OEM part and literally 5 mins work.

I had a gas cap failure on mine as well, which happened while I was driving it back to Phoenix from Albuquerque (right after I bought it). I was relieved that a gas cap was all I needed.

I was gonna suggest Gas Cap as well ... Might wanna start there first

What are the actual codes it's throwing?
