Kia Sorento 2010-2018 Oxygen Sensor (Air Fuel Ratio Sensor) 39210-2G150

When your Kia Sorento idle is unstable, fuel consumption increases, engine light on, or acceleration feels weak and exhaust odors worsen, it usually indicates the oxygen sensor has aged or failed; it cannot accurately monitor exhaust oxygen. The sensor, when functioning properly, feeds oxygen concentration data to ECU to precisely adjust fuel injection for best air-fuel ratio, improving fuel economy and emission cleanliness. OEM number 39210-2G150, compatible with 2010-2018 Sorento and alternative numbers 290960362, 25024916, 7481779, etc. Install after engine cools; remove old sensor with a special socket, avoid damaging threads or wiring; tighten to specified torque to ensure proper sealing.
