I have done searches on here and found conflicting descriptions of where this Oxygen Sensor is located. I have a 2002 GS300. I believe it is on the passenger side but do not know if it is the one closest to radiator or the one near the firewall. Anyone help?

 

Its on the passenger side, closest one towards you. So the one near the radiator

 

The one nearest to the headers

 

that is the easy one. Is each sensor color coded with a different piece of tape? This one has blue tape around it?
