Detailed Product Overview

Use the Spectra OS6183 when servicing the emission control system on a 2004 Nissan Pathfinder. This oxygen sensor is engineered as a replacement for the original sensor location and is intended to restore accurate exhaust-gas feedback for the downstream left position. The OS6183 part number is also useful when cross-checking listings for the 2004 Nissan Pathfinder oxygen sensor application.

Common Issues This Sensor May Address

• Check engine light related to oxygen sensor performance
• Fault codes tied to downstream left sensor readings
• Reduced emissions-system monitoring accuracy
• Failed inspection due to sensor-related emissions faults
• Incorrect exhaust feedback from a worn sensor

Installation Notes and Tips

Confirm the downstream left location before ordering and compare the connector and harness routing to the removed sensor. For best results, inspect the exhaust threads and surrounding wiring before installation, and clear diagnostic trouble codes after the repair is complete. Verify the 2004 Nissan Pathfinder fitment and position match the vehicle before installation.
