GM code 141 refers to a diagnostic trouble code (DTC) indicating a problem with the oxygen sensor circuit, specifically for the sensor located in the exhaust system before the catalytic converter. It typically means that the oxygen sensor is reading a voltage that is outside the expected range, which can affect engine performance and emissions. This issue may require inspection of the sensor itself, wiring, or related components to determine the root cause. Addressing this code is important for optimal engine operation and compliance with emissions standards.
