Hi there, just wanted to confirm something, i've been reading the threads about this, any help would be appreciated!

2003 4runner Sport (v6, 1GR-FE)

Computer Error Code P0136, Bank 1, Sensor 2. The dealership wants a bunch of $$ to change the sensor out, they are confident that the sensor is the problem.

I wanted to double-check the location and part as i'm just going to do it myself.

Is this right:
- On this motor, Bank 1 Sensor 2 is located on the passenger side of the vehicle after the catalytic converter (rear)?
- Is the correct replacement part a Denso 234-4805 (OE) or a Bosch 13355?

And, is there any reason to get the Denso as opposed to the Bosch? I can get a Bosch locally, the Denso i'd have to order. The Denso costs more but not enough that it bothers me at all, either of these are almost free considering what the dealer wanted to fix it.

I've got the service manual and it looks like this is about 15 minute job.

thanks in advance!

I would stay as close to OEM as possible. I have had some bad experiences in the past with aftermarket O2 sensors. Just my $.02
