Code P1115 KIA Description

The P1115 code for KIA vehicles indicates an issue with the HO2S (Heated Oxygen Sensor) Circuit Low Voltage for Bank 1 Sensor 1. The HO2S sensor is responsible for monitoring the oxygen levels in the exhaust gases and providing feedback to the engine control module (ECM) for proper air-fuel ratio adjustments. When the sensor detects low voltage in Bank 1 Sensor 1, it means that there is a problem with the sensor's ability to accurately measure oxygen levels in the exhaust gases. This can lead to poor engine performance, reduced fuel efficiency, and increased emissions.
