Fault code P2197
Hey guys. Maybe you can help me with this one. The check engine, VSC and traction control lights recently came on on my 2008 RX350. I pulled fault code "P2197 O2 sensor signal, stuck lean bank 2, sensor 1". Is this really a bad O2 sensor or is it the air/fuel sensor? I see the parts store carries both. Just trying to figure out which Denso part to order. Does anyone have the correct part number? Thanks!
