2018 Cadillac CTS Heated Oxygen Sensor Used OEM 12652845

Genuine Cadillac OEM Heated Oxygen Sensor (O2 Sensor) (part number 12652845). This sensor is located in the exhaust system and measures the amount of oxygen in the exhaust gas. This data is critical for the engine control unit (ECU) to maintain the correct air/fuel ratio for optimal engine performance, fuel efficiency, and reduced emissions. The "Heated" part indicates it warms up quickly for accurate readings sooner. Failure leads to poor fuel economy, rough running, and a check engine light; replacement is essential for proper engine management. The VIN for this vehicle is 1G6A85SX2K0104094.
