I have a 2002 SC430. I have P0155 (H02S) Heater Circuit Malfunction Bank 2 Sensor 1.
I need to know this location in the car and how to replace the Bank 2 Sensor 1.
The Lexus dealer gave me the price $150 just for diagnostic the problem. I think I could do it with your great instruction.
Please help
Thanks in advance
Oldman
