Fault code C3204

[Crippenator]

Hi!

I just got fault code C3204 on a -00 Yaris/Vitz/Echo. 

I really have no idea where to begin.

Have had som previous fault codes in the style of "bank 1 too lean" or similar, but that comes and goes depending on the outdoor temperature (below -15c, goes away). 

Now, I've looked around the web, even asked chat GPT, and my only lead seems to be some kind of "Steering angle sensor".
However, I'm quite sure that no such sensor exists on a -00 Yaris........

Help! What could this be?

Is it an Automatic, what engine ?

This could tie in with your ' bank 1 too lean ' if you read right down at the bottom it seems air fuel ratio is incorrect and give you a idea what to check.

C3204 is manufacturer specific
