I have a OBD code of P1647 on my 2005 Vanden Plas. I've researched the code and believe it is the Bank 2, upstream Oxygen sensor with a Denso part# of 234-9030.

Does anyone have a picture or diagram of where this sensor is on the 2005 4.2L engine? and is this the correct sensor for the OBD code? and correct Denso part#?

Just looking for verification before I start this repair effort.

Thanks

The upstream sensors are underneath the car sticking out or around the catalytic converters.
