Bosch 13022 Oxygen Sensor - Upstream

Bosch Oxygen Sensor for Upstream Emissions Control

Bosch Part Number 13022 is a narrow-band, non-heated oxygen sensor built for specific upstream applications. It provides the ECU with air-fuel-ratio feedback needed for stable combustion control and lower emissions, making it a direct-fit choice for select Saturn, Chevrolet, GMC, Isuzu, Pontiac, and Oldsmobile vehicles.

As part of the Bosch Engineered Oxygen Sensor line, this sensor reflects Bosch’s OE development history in oxygen sensing, including narrowband designs that support faster closed-loop operation and accurate lambda feedback under changing engine conditions.

Key Features

• Specific-fit upstream oxygen sensor for targeted vehicle applications
• Narrow-band, non-heated sensor design
• Threaded mounting with 18 mm thread size and 22 mm hex size
• Male connector and male blade terminal configuration
• Wiring harness included for application-specific installation
• Steel-finish metal housing for durability in exhaust environments
• Bosch Part Number 13022 for easy identification

Detailed Description

Bosch 13022 is engineered for upstream exhaust placement where the sensor monitors oxygen content before the catalytic converter. That signal helps the engine control module adjust fuel delivery during closed-loop operation. This is a practical replacement for drivers searching for a Bosch oxygen sensor for 1995-2002 Saturn SC1 upstream, Bosch oxygen sensor for 1999-2000 Chevrolet S10 upstream, or Bosch oxygen sensor for 1999-2000 GMC Sonoma upstream applications.

Compatible vehicle coverage includes select Saturn SC1, SC2, SL, SL1, SL2, SW1, and SW2 models, along with Chevrolet Cavalier, Malibu, and S10; GMC Sonoma; Isuzu Hombre; Oldsmobile Alero; and Pontiac Grand Am and Sunfire. If you are replacing a Bosch 13022 oxygen sensor on a Saturn SL2 upstream or a Chevrolet S10 upstream application, this part is built to match the listed fitment and connector style.

This part cross-references 12563312 and 24576791 for the same application.

What It Helps Address

• Check engine light concerns related to upstream oxygen sensor performance
• Rich or lean fuel trim conditions caused by inaccurate O2 feedback
• Rough idle or unstable combustion control tied to sensor degradation
• Failed emissions testing linked to improper air-fuel monitoring
• Slow or inconsistent closed-loop fuel control response

Installation Notes and Tips

Confirm the connector shape, terminal count, thread diameter, and upstream position before installation. This Bosch 13022 oxygen sensor uses a threaded mount, 18 mm thread size, and a round male connector with a single blade terminal. Verify whether the vehicle is equipped with California emissions equipment where noted in the fitment data, especially on select 2000 Saturn applications. Use proper exhaust sensor removal tools and inspect the harness routing to avoid heat damage.

Quality Assurance

Bosch draws on more than five decades of OE oxygen sensor development, and this sensor is built with ceramic sensing elements, controlled heater strategy where applicable to the product line, and high-temperature-resistant materials for consistent operation in harsh exhaust conditions. Bosch Part Number 13022 is a standard replacement sensor designed to meet the listed application requirements.
