My car needs a new o2 sensor and the OBD2 scanner said the code was P0135 which is the front oxygen sensor on bank 1. Im not very knowledgeable on this type of stuff and was wondering if someone could point me in the right direction of which one to order online off eBay, amazon, etc. I really dont want to order the wrong sensor or one for a non-VVti engine. Any help is much appreciated. My car is a 2000 SC 300

I screenshot this from the densoautoparts.com website. Denso makes the sensors for Toyota.

2000 SC300
Downstream rear is the sensor in the front pipe under the passenger foot well
Upstream front is the sensor for cylinders 1-3
Upstream rear is the sensor for cylinders 4-6




You can also try ebay and amazon. Just search "Denso oxygen sensor [part #]" and you'll find it

So based on the error code you think I need to purchase the Upstream Front one?

Im so confused... On the site you linked me it says Denso 234-4626 is an Upstream front sensor. On amazon it says that exact same sensor is Downstream rear: So i dont know which to buy lol.

Can the same sensor be used for upstream and downstream?

Yes, but the wiring attached to it will be either be too short or too long.
FYI I'd trust the Denso website before I trust a seller on amazon
