My fiancees Sonata came up with a code P1154, and said to check manufactureres book for specifics. Does anyone know where to find codes meanings? Thanks.

 

It means O2 sensor circuit- Transition switch time Malfunction (Bank2-Sensor1).

You can find a list of codes, and how to fix it on www.hmaservice.com . It is like haveing your own shop manual online.

 

thanks...I am still trying to find the codes on hmaservice though...is it under TS, ETS or someting else?

 

I have also posted up all the codes here on this forum. If you do a search, you should find them.

 

It was both 02 sensors...i guess that they had a recall on them that not everyone was told about, so if u have a 1999 or 2000 Sonata, as your dealers about the recall.
