Spectra OS5173 Oxygen Sensor - Downstream

Spectra OS5173 Oxygen Sensor for Nissan Maxima

The Spectra OS5173 oxygen sensor is a direct-fit emission control replacement for the 2000 Nissan Maxima downstream position. It is built to meet or exceed original equipment performance expectations for accurate exhaust monitoring and dependable engine management.

Key Features

• Direct-fit oxygen sensor for the downstream location
• Fits 2000 Nissan Maxima, downstream, for vehicles with Federal Emissions
• OE-style replacement engineered for emission control service
• Supports proper air-fuel ratio feedback to the engine control system
• Cross-references Delphi ES20396 and BBB Industries 13969 for the same application

Detailed Description

Spectra OS5173 is an emission control sensor made for the 2000 Nissan Maxima downstream position with Federal Emissions. As an oxygen sensor, it monitors exhaust oxygen content after the catalytic converter so the vehicle’s control system can evaluate exhaust performance and maintain proper fuel delivery. Spectra Premium states that its engineering, manufacturing process, and quality control are used to deliver replacement sensors that meet or exceed original equipment performance.

This part cross-references Delphi ES20396 and BBB Industries 13969 for the same application. If you are searching for a 2000 Nissan Maxima downstream oxygen sensor or a Spectra OS5173 replacement oxygen sensor, this part matches the confirmed fitment listed here.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect exhaust oxygen readings at the downstream sensor location
• Fuel control issues caused by a worn or slow-responding sensor
• Emission test failures tied to sensor output problems
• Reduced catalytic converter monitoring accuracy

Installation Notes and Tips

Install the sensor in the downstream position only on the confirmed application: 2000 Nissan Maxima with Federal Emissions. Verify connector style, routing, and thread condition before installation, and follow the vehicle service procedure for sensor removal and torque specification.

Quality Assurance

Spectra Premium uses engineering, manufacturing technology, and quality control processes intended to deliver oxygen sensors that meet or exceed original equipment performance standards for the replacement application.
