    P1130 Air/Fuel Ratio Sensor Circuit Range/Performance Malfunction (Bank 1 Sensor 1)
    Bank one on that engine is at the windscreen side of the engine, that code is usually pretty valid on a Lexus, use a direct fit replacement Denso brand sensor.

    I had this reset and 5 miles down the road it came back on. What effect will this have? It hasn't seemed to affect the engine performance. Still is normal.
    And thank you for your responce.

    re setting does nothing. you need to repair the failure. it will eventually cause driveability issues. I would not ignore it.

    agree with Pat. do not go for a cheap sensor. get a good quality sensor. the air/fuel sensors are expensive but well worth it.
