Bosch 15341 Oxygen Sensor

Bosch Validated Oxygen Sensor for Select Hyundai and Kia

Bosch Validated Oxygen Sensor Part Number 15341 is a narrow-band heated O2 sensor built for specific Hyundai and Kia applications. It delivers air-fuel-ratio feedback to the ECU for stable closed-loop control, accurate combustion management, and lower emissions across changing operating conditions.

Key Features

• Specific-fit oxygen sensor for direct application matching
• Narrow-band heated design for faster sensor response
• 4-wire configuration with blade terminals and oblong connector
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Wiring harness included with 26.7 in harness length
• Metal housing with high-temperature-resistant construction
• Standard replacement grade for OE-style service

How Bosch Validated Oxygen Sensor Line Performs

The Bosch Validated Oxygen Sensor line draws on Bosch OE development in oxygen sensing technology, including early thimble designs and later planar narrowband sensors that improved light-off speed, lambda accuracy, and closed-loop operation. Part Number 15341 uses a heated narrow-band sensor element and optimized heater control to maintain consistent signal quality under thermal and vibration load. This makes it a practical replacement for Hyundai Veracruz, Hyundai Azera, Hyundai Genesis, Hyundai Sonata, Kia Sedona, Hyundai Santa Fe, Kia Amanti, Kia Sorento, and Hyundai Entourage applications where precise exhaust feedback is required. This part cross-references 392103C200 and 392103C600 for the same application.

What This Oxygen Sensor Helps Address

• Check engine light related to oxygen sensor signal faults
• Rough idle or unstable air-fuel control
• Reduced fuel economy caused by inaccurate exhaust feedback
• Emissions test failures tied to sensor response issues
• Delayed closed-loop operation after startup
