P11EE Cylinder 3 Air-Fuel Raito Imbalance (Port)

Anyone else have this CEL code come up? If so, what did you end up having to replace?

I recently purchased a used 2017 TRD Sport with 81k miles on it. So I believe the initial warranty has since expired...

 

That code could literally be anything in the fuel or air induction system, vacuum leaks and exhaust leaks would be the easiest things to check for.
There's another thread about it here OP was running 91 octane fuel and apparently switching back to 87 fixed his problem.
I've included some reading material for that code below.

 

any1 elses dilema doubtful will help U

warranty is of NO matter

OXYGEN SENSORS are cheap...........the code narrows the issue to the correct AREA

its typically nothing major
