My 05 RX needs a heated 02 sensor but I can't seem to get a straight answer. I am wandering if anyone on here have a part number it's bank 1 sensor 2 and possibly a picture of where this sensor is. Thanks any help would be greatly appreciated

 

Sensor 2 is the sensor AFTER THE CATALYTIC CONVERTER which is located at the rear of the exhaust manifold. It is the rear 3 cylinders manifold located near the firewall just below the manifold transition to the single pipe going to the catalytic converter. You will have to get under car to change,

 

Like many topics you might have questions about, this one as been discussed previously and on multiple occasions. You just need to spend some time using the search tools of the forums. Such as:
