Code P1132 Saturn Description
The P1132 diagnostic trouble code (DTC) for Saturn vehicles indicates a problem with the H02S (Heated Oxygen Sensor) circuit on Bank 2 Sensor 1. This sensor is responsible for measuring the oxygen content in the exhaust gases and sending this information to the engine control module (ECM) for proper fuel management. The "Low Variance" aspect of the code suggests that the voltage signal from the sensor is not fluctuating as expected, which can lead to inaccurate readings and affect the overall performance of the vehicle.
