Mazda 2 (2002 Demio Sport) pre-cat oxygen sensor place?
 

Hi I'm new here, driving Jap import 2002 Demio for almost 5 years. I just keep getting pre-cat oxygen sensor fault code but I cannot locate where it is. Engine is 4at 1.5 liter 113ps zy-ve. Mazda's schematics shows where it is;

Mazda MAZDA 2 DY 2003-01 Mazda Engine Switches & Relays (18-861b coded part)

But it's not there. I'm confused. I would be happy if anyone knows exact location.:confused:

Lean forward and look down between the engine and bulkhead and you will see it in the manifold. Thats the first sensor (sensor 1 bank 1 )
