Code P1196 RAM Description

The P1196 code indicates a slow response from the Heated Oxygen Sensor (HO2S) located in Bank 2 Sensor 1 of the vehicle's exhaust system. The HO2S is responsible for monitoring the oxygen levels in the exhaust gases and sending this data to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. A slow response from the sensor can lead to inaccurate readings, affecting the engine's performance and emissions.
