Lexus RX300 How to install a Air/Fuel Sensor part# 2349009

This answer was rated:

How to install a Air/Fuel Sensor part#(NNN) NNN-NNNNin a 2001 Lexus RX300

I'm not showing that part number as a valid OEM#, nor is it matching with any aftermarket part number that I have access to. There are 2 A/F Sensors on this vehicle, of which both have the same part #. ANy chance you have a "p-code" that led you to a faulty A/F sensor, or happen to have the Bank #?

Here's the info you requested: Bank 2 Sensor 1

I got ther part number online when I looked for a Lexus A/F sensor. Maybe it's the Denso OE part number

Ok- no Prob. Bank2 Sensor1 was all I needed.

 

This is actually a piece of cake to change. This A/F Sensor is located on the side of the engine closest to the front of the vehicle, mounted to the exhaust manifold. There is a special tool - Oxygen Sensor Socket - that makes this job even easier. You can usually rent (or buy cheap enough) from any parts store. Remove the "NEG" cable on the battery then simply unplug the electrical connector, then remove the sensor (very similar to a spark plug). Install the new sensor and plug it in. Reconnect the "NEG" cable and you should be good to go.

Just to be sure before I buy it from Denso , do I have the right part?

Yes. I just do not have access to Denso part#'s. I've only got OEM and "Standard"brand. There are only 2 A/F Sensors on this vehicle, and they are both the same part#.
