Code P0132 Scion Description

The P0132 Scion code refers to a problem with the HO2S11 (Heated Oxygen Sensor 1 Bank 1) circuit having high voltage. The HO2S11 sensor is responsible for measuring the oxygen content in the exhaust gases and sending this information to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the voltage from the sensor is higher than normal, it indicates that there is an issue with the sensor or its circuit.
