I've searched and it's still not clear to me of some O2 sensor locations that are in the 2007 RX 350. Parts suppliers refer to sensors as, e.g. Right Upstream and Left Upstream. How do I determine the right and left hand side of this transverse mounted engine? Hood up and facing the engine from the front bumper. P00051 is a Bank 2 Sensor 1 failure. Is that sensor that is nearest the radiator Upstream Left and the other nearest to the firewall Upstream Right?
It would be nice to have a graphic with all the information on one page. I will post one if I can get the data. I have the drawing already and I would like to mark it up radiator and firewall, Bank 1 and Bank2, Left and right, and Denso part numbers. That would put an end to annoying posts like mine once and for all. At least for Upstream
