Bosch 15076 Oxygen Sensor - Downstream

Bosch 15076 Oxygen Sensor Overview

Bosch 15076 is an Actual OE Oxygen Sensor built as a narrow-band heated downstream replacement for select Hyundai and Kia applications. It provides precise air-fuel-ratio feedback to the ECU, helping maintain stable combustion control and lower emissions across changing operating conditions.

Compatible with 1997-2001 Hyundai Accent, Elantra, and Tiburon applications, plus 1998-2001 Kia Sephia and 2000-2001 Kia Spectra downstream positions, this Bosch oxygen sensor is a direct-fit service part for vehicles that require OE-style sensor performance.

Key Features

• Actual OE Oxygen Sensor from Bosch
• Narrow-band heated sensor design for faster closed-loop operation
• Specific-fit replacement with threaded mounting
• 4-wire harness with rectangular male connector
• 22.1 in wiring harness length and 20.9 in sealing-surface-to-connector length
• 18 mm thread size with 22 mm hex size
• Metal housing with high-temperature-resistant construction

Product Details

Bosch developed its oxygen sensor technology from early OE designs and later planar narrowband formats that improve light-off response and lambda accuracy. The Bosch 15076 uses advanced ceramic elements and controlled heater operation to deliver consistent signal output under heat and vibration. For drivers searching for a downstream oxygen sensor for Hyundai Tiburon, Hyundai Elantra, or Kia Spectra, this part number 15076 provides OE-proven sensor architecture for emissions monitoring and fuel-control feedback.

This part cross-references 0K2AB18861 for the same application.

What This Sensor Helps Address

• Check engine light related to downstream oxygen sensor faults
• Incorrect air-fuel ratio feedback to the ECU
• Emissions test failures caused by sensor degradation
• Slow sensor response during closed-loop operation
• Rough combustion control from an aging narrow-band sensor

Installation Notes

Verify the connector shape, 4-wire configuration, and 18 mm thread size before installation. This Bosch 15076 oxygen sensor is a specific-fit, threaded replacement with a male rectangular connector and included wiring harness. Confirm downstream placement and vehicle application details for the exact Hyundai or Kia model before service.

Quality Assurance

Bosch supplies OE-developed oxygen sensor technology to the aftermarket, using durable materials and heater control strategies proven in demanding thermal and vibration environments. Part number 15076 reflects Bosch’s Actual OE approach for consistent sensor performance in the listed Hyundai and Kia applications.
