Code P0430 - which parts do I need?

Hi everyone.

I’ve been monitoring our v8 4runner flashing a check engine light.

I thought it was an 02 sensor so I used a gas treatment, which cleared it initially.

now I’ve bought an obdII scanner and I can see what’s up.

this is an 04 v8 runner with 215k. Runs great otherwise.

have any of you been though this and can advise me what parts I need please?

thanks in advance.

 

More than likely the o2 sensor needs to be replaced

 

@hvac guy thanks! Any ideas which one?

 

I believe it’s the rear passenger side( the one behind the cat) closest to rear

 

@hvac guy I've ordered 89465 A LH and RH side because i think i should swap both at same time.

All in $99 from RockAuto - i plan to fit them myself when i can borrow a buddy's garage floor - too cold here in NYC to be working on the street!

 

I would definitely get the denso sensors or get them from a dealer or online dealer

 

Yep I got denso sensors from rockauto
