Bosch 18152 Oxygen Sensor - Downstream Right

Bosch Validated Oxygen Sensor for Sorento

Bosch Validated Oxygen Sensor 18152 is a specific-fit, narrow-band heated O2 sensor for emission control service. It is built for precise air-fuel-ratio feedback to the ECU, helping maintain stable combustion control and lower exhaust emissions.

Compatible with 2007-2009 Kia Sorento, downstream right, this Bosch oxygen sensor supports accurate closed-loop operation in the vehicle’s exhaust system. The Bosch Validated Oxygen Sensor line reflects Bosch’s OE development background and focus on durable sensor performance under heat and vibration.

Detailed Description

Bosch 18152 is a standard replacement oxygen sensor engineered for downstream right placement on the 2007-2009 Kia Sorento. As a narrow-band heated sensor, it provides the ECU with switching-type oxygen feedback used to manage fuel control after the engine reaches operating temperature. Bosch’s sensor design uses ceramic sensing elements, controlled heater operation, and high-temperature materials to support consistent signal output in demanding exhaust conditions.

This part cross-references 392103C970 for the same application. If you are searching for a Bosch oxygen sensor for Kia Sorento 2007-2009 or a Bosch Validated Oxygen Sensor 18152 replacement, this unit matches the confirmed downstream right fitment listed here.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio feedback to the ECU
• Delayed closed-loop fuel control after warm-up
• Rough combustion control caused by a worn downstream sensor
• Emissions test failures tied to sensor signal degradation

Installation Notes and Tips

Install this sensor in the confirmed downstream right location on 2007-2009 Kia Sorento applications. Verify the 18 mm threaded bung, 22 mm hex size, connector shape, and harness routing before installation. Because this is a heated narrow-band sensor with an integrated harness, match the connector and wire layout to the original unit and inspect the exhaust threads for damage or contamination.

Quality Assurance

Bosch has more than five decades of OE oxygen sensor development and supplies aftermarket sensors built from the same engineering foundation used by vehicle manufacturers. Bosch Validated Oxygen Sensor 18152 is produced as a durable, OE-proven replacement for emission control service.
