Question about 2003 Lexus RX 300
What part do i need to fix this and which sensor should I replace
You need a new O2 sensor. There is a special slotted socket used to fit on this part for removal. Just buy the sensor first, then try slipping the socket on the part to see if it fits.
The idea of the heater is this. They want your O2 to reach maximum operating temperature sooner than later. So they install a heating element inside the part to speed heating up. When the O2 is hot, the engine RPM and fuelmix will change to a leaner setting.
You can try disconnecting and reconnecting the wire first to insure that the connector is just not dirty. But chances are it will set a lost signal Code by doing it. You need to look at a diagram online for the engine definition about which bank is bank one. Usually sensor one is the first sensor starting with the engine and sensor 2 is further downstream.
You may be able to get a chart from the autoparts store to show you the location of your troubled part. Some stores will even print a copy for you.
Please rate my info.

the O2 sensor for bank one sensor one is located between the catalytic converter and the engine in the exhaust head pipe. see photo of your engine cylinder layout, the sensor u want to replace is the one at the cylinder #1 bank on right.

P1410 - Fuel Tank Pressure System
P0441 - Evaporative Emission Control System Incorrect Purge Flow
P0773 - Shift Solenoid Electrical
P0446 - EVAP Vent Solenoid Valve Control System
Ok, above are the codes listed on your description and there respective definitions. the P0441 and the P0446, basically run parallel and they mean the same thing. Its concerning the disposal of fuel fume waste that is burned in the EVAP canister during the EVAP process. the EVAP vent solenoid valve will have to be replaced.
The P1410 can be resolved be replacing the fuel pressure regulator which is part of the fuel pump assembly. I would also make sure the gas cap is correctly screwed on and its tight and mot lose.
The P0773 is quite different than the others. this concerns the solenoid that is located in the transmission pan. the scan has detected a malfunctioning solenoid that may ****** the shifting cycle of your transmission.
The EVAP situation will fail the emission's test if not fixed but, this shift solenoid issue, although not an emission's issue, should be check and fix soon.
Please rate and god bless:)

#1 stay away from Ottozoo. #2 have a good repair shop check it out. Most likely the A/F ratio sensor (oxygen sensor) is bad. the BLACK wire is power for the heater, so if the BLACK wire has power, replace the A/F ratio sensor.
