I have Lexus 2005 Rx400h MHU38R-AWXGKW uk model. I been given error code P2197 which says Oxygen (A/F) sensor signal struck lean (Bank 2 sensor 1) by my regular mechanic and a suggested part number by Lexus dealer as 89467-48060.
I understand that there are 4 sensors.
Firstly where does this sensor fit and is the part number correct for the error code description. Please advice.
Many thanks in advance
