Spectra OS5064 Oxygen Sensor - Upstream

Spectra OS5064 Oxygen Sensor

The Spectra OS5064 oxygen sensor is an OE-style emission control replacement for select Saturn, Chevrolet, GMC, Isuzu, Oldsmobile, and Pontiac applications. It is built for upstream sensor locations and supports accurate air-fuel feedback for vehicles such as the Saturn SC1, Saturn SL2, and Chevrolet S10.

Key Features

• Upstream oxygen sensor for emission control systems
• OE-replacement design for direct-fit service on listed applications
• Built with Spectra Premium engineering, manufacturing technology, and quality control standards
• Cross-references Bosch 13022 and NTK 21039 for the same application
• Part number OS5064 for catalog and fitment lookup

Detailed Description

Spectra OS5064 is an upstream oxygen sensor for 1995-2002 Saturn SC1, SC2, SL, SL1, SL2, and SW2; 1999-2000 Chevrolet S10 and GMC Sonoma; 1999 Isuzu Hombre; and 1999 Chevrolet Cavalier, Malibu, Oldsmobile Alero, Pontiac Grand Am, Pontiac Sunfire, and Saturn SW1. It is also a fitment match for vehicles in the same application family where the original sensor location is upstream. The OS5064 is engineered to meet or exceed the performance of the original equipment sensor it replaces, helping maintain proper exhaust feedback for the engine control system.

This part number, OS5064, is a direct replacement choice for drivers searching for an upstream oxygen sensor for Saturn SL2, Saturn SC1, or Chevrolet S10 applications.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture feedback
• Reduced fuel control accuracy from a worn upstream sensor
• Emission system faults tied to sensor response issues
• Service replacement for aging OE oxygen sensors

Installation Notes and Tips

Confirm the sensor position before ordering; this listing is for upstream applications only. Match the vehicle year, make, model, and any notes shown in the fitment data, including 1999 Chevrolet Malibu and 1999 Pontiac Grand Am with RPO Code RC9. Verify connector style and thread engagement against the original sensor before installation.
