Q: What does code P1130 mean?

Air/Fuel Sensor Circuit Range Performance Bank 1 Sensor 1. P1130 on a Toyota means the engine computer has detected that the air/fuel ratio sensor on bank 1, sensor 1 is not reporting a plausible range of values during a specific test window. The sensor is a wideband current-measuring device, and the ECU compares its signal against what the engine's operating conditions predict; when the signal stays too lean, too rich, or fails to respond within the expected window, this code is stored.
