Question

2009 Kia Sorento with engine code P2A01. What is the cause of this code? Where is the location of this oxygen sensor? How can it be repaired? and what would I be looking for?

Answer 1

P2A01 is for bank 1 sensor 2 but I dont see that code in the manual 

there is no clear picture on which side it is on, but you follow the wiring from the picture below 

sensor is 2 near the catalytic converter, it should not be hard to find

Answer 2

P2A01 KIA Code - O2 Sensor Circuit Range/Performance Bank 1 Sensor 2
