Oxygen Sensor Location On D4D

[dnl_303]

Hi all,

I need to change the oxygen sensor on my 2003 Toyota Avensis d4d.

Can someone please point me in the right direction as to where I can find this sensor, as have been all over the engine bay and underside and can't seem to locate it anywhere. The only place I can't really see is the turbo area due to limited access. Have I missed it or is it towards the rear between engine and firewall?

Any help much appreciated as can't afford to take it to the main dealer.

Cheers,

Daniel

Hi,

On the 1ZZ/3ZZ-FE engines, the heated oxygen sensor is like in the below picture.

Hi,

That's great - thanks for the diagram. I have a flexible pipe where the oxygen sensor should be according to diagram, but I'll look further up as couldn't get directly beneath firewall yesterday.

Will post any updates.

Cheers,

Daniel
