I have Es 330, 2004 with an error code P2241, bank 2 sensor 1.
Any advise to fix it myself and where is the sensor located?
If I have to buy it any recommendations as i tried from Amazon but i find sensor 2.
Thanks a

lot

 

Hello,

If I understand correctly, P2241 means that the data sent by Air/Fuel Ratio sensor is lower than ECU expects. It is probably just a bad Air/Fuel Ratio sensor, in your case, it is the one towards the radiator. To make sure, you can warm-up the car, and then take a look at the ECU's live data - A/F sensor output should be around ~2.9-3.3V.

Hope this helps and best of luck!
