Bosch 16064 Oxygen Sensor - Downstream Left

Bosch 16064 Oxygen Sensor Overview

Bosch 16064 is an Actual OE Oxygen Sensor built as a narrow-band heated replacement for precise air-fuel-ratio feedback to the ECU. It is a specific-fit sensor with a threaded mount, 4-wire harness, and oblong male connector for direct replacement on select Saturn applications.

Fits 2001-2005 Saturn L300, downstream left. Fits 2001-2003 Saturn LW300, downstream left. Fits 2000 Saturn LS2, downstream left. Fits 2000 Saturn LW2, downstream left.

Key Features

• Actual OE Oxygen Sensor from Bosch
• Narrow-band heated sensor design for closed-loop fuel control
• Specific fit with included wiring harness
• 4-wire configuration with blade terminals and male connector
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Steel finish and metal housing for high-temperature service
• Wiring harness length: 37.6 in; overall length: 40.9 in

Product Details

Bosch 16064 uses a switching-type narrow-band design to measure exhaust oxygen content and send accurate feedback to the engine control unit. Bosch developed this sensor line from its original OE oxygen sensor technology and later planar narrowband designs, focusing on faster light-off, stable lambda control, and reliable operation under heat and vibration. For drivers searching for a Bosch 16064 oxygen sensor for Saturn L300 downstream left or a Bosch 16064 replacement for Saturn LW300, this part matches the listed OE-style application and mounting format.

This part cross-references 9182000 for the same application.

What It Helps Address

• Incorrect air-fuel mixture readings
• Delayed closed-loop fuel control
• Check engine light concerns related to oxygen sensor performance
• Rough combustion control caused by aging sensor response
• Emissions-related drivability issues on Saturn L300, LW300, LS2, and LW2 applications

Installation Notes

Install in the downstream left position only where listed in the fitment data. Confirm the 18 mm thread size, 22 mm hex, 4-wire connector layout, and harness length before installation. Because this is a specific-fit sensor, verify connector shape and routing against the original part on the vehicle before final tightening.

Quality Assurance

Bosch backs this oxygen sensor line with more than five decades of OE development and aftermarket supply experience. The sensor uses ceramic elements, controlled heating, and high-temperature-resistant materials to support consistent operation in demanding exhaust conditions.
