Code P1133 Suzuki Description

The P1133 Suzuki diagnostic trouble code (DTC) refers to the oxygen sensor located in bank 1, sensor 1, which is responsible for monitoring the oxygen content in the exhaust gases of the engine. Specifically, this code indicates that there have been too few transitions detected from rich to lean (or vice versa) by the oxygen sensor. This can signal an issue with the air-fuel mixture being too rich or too lean, affecting the engine's performance and emissions output.
