Bosch 15130 Oxygen Sensor - Downstream

Bosch Validated Oxygen Sensor for Downstream Control

Bosch Validated Oxygen Sensor 15130 is a specific-fit, narrow-band heated O2 sensor built for downstream exhaust monitoring. It delivers precise air-fuel-ratio feedback to the ECU, helping maintain stable combustion control and lower emissions in supported applications.

Key Features

• Specific-fit oxygen sensor for direct application matching
• Narrow-band heated design for faster closed-loop operation
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• 4-wire configuration with female connector and pin terminals
• Steel-finish metal housing for high-temperature exhaust service
• Wiring harness included with 11.5 in harness length
• Overall length: 15 in; sealing surface to connector end: 13.8 in

Product Details

Bosch 15130 is part of the Bosch Validated Oxygen Sensor line, a product line focused on OE-style replacement coverage and application validation. Bosch has decades of oxygen sensor development behind its narrow-band heated designs, using ceramic sensing elements, controlled heater operation, and heat-resistant materials to maintain accurate signal output under thermal and vibration stress. This sensor is a direct replacement choice for downstream monitoring on vehicles such as the 2007 Buick Rainier, 2007 Chevrolet Trailblazer, 2007 GMC Envoy, and 2007 Saab 9-7x, as well as 2006 Buick Rainier and 2006 Chevrolet Trailblazer EXT applications.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Sensor Helps Address

• Check engine lights related to oxygen sensor performance
• Slow or inaccurate downstream O2 sensor readings
• Rich or lean fuel-control feedback issues
• Emissions test failures tied to sensor response problems
• Closed-loop operation concerns after sensor aging or contamination

Installation Notes and Tips

Verify connector shape, wire count, thread size, and downstream location before installation. This Bosch 15130 uses a trapezoid female connector, 4 female terminals, and a threaded 18 mm mounting design. Confirm vehicle-specific fitment for the exact year, make, model, and emission package, including California Emission System listings where noted. Use proper oxygen sensor service tools and inspect the exhaust bung threads and wiring routing before final tightening.

Quality Assurance

Bosch backs this oxygen sensor with OE development experience and validated aftermarket application coverage. The design reflects Bosch’s long-running work in oxygen sensing technology, including narrow-band heated sensors used for accurate exhaust feedback in demanding operating conditions.
