2002 Hyundai Sonata..
 

I recently put up a post Re: (CODES) but I forgot to mention the make of
my Hyundai its a 2002 Sonata, re: the P1154 H02S and Power Steering Leak
problem, can something be done to secure the leak? Or am I stuck replacing
the entire hose thingy? Also what can be done to fix the code problems? P
1154 I found out stands for Transition Time Ratio, and H02S stands for
Heated Oxygen Sensor. How do I fix this???
