Lexus Repair: How to replace the oxyzen sensor in the front, mechanic shop, lexus es300

Question
Hi:

It was nice to see a reply from you. I have no clue of what you said. Can you be little more clear. I am not really sure of what sensor it is. I said Bank1 but not really sure. I think the Sensor in the front side might have been damaged. Can you give me a more clear solution. Please remember that i am an Illiterate in this field.

Waiting for your reply,
Rakesh

Hi:

I have LEXUS ES300, 94 model. Recently i went to mechanic shop and he decoded the computer and it said that one of the O2 Sensor in the Bank1 is messed up ( I am not sure of whether what bank it said). Can you please tell me how to replace the Sensor in the front. I am completely unaware of it. This is my first car till now, so no Idea at all.

Waiting for your reply,
Ray

Bank 1 is the right hand bank. That's the rear bank (firewall side).
You just unclip the wiring harness & unbolt the sensor with an o2 sensor wrench.

Answer
It's the sensor on the backside of the engine.

It will exactly go over oxygen sensor replacement in the 1mz-fe section words & illustrations.


You unhook the electrical connector, and then unscrew the sensor with a special oxygen sensor socket.
