Detailed Fitment and Function

Designed for downstream exhaust monitoring, the Spectra OS5206 helps the engine control system evaluate catalytic converter efficiency and maintain proper fuel control strategy. This part number, OS5206, is a fitment-based replacement for select Metro, Swift, Tracker, Firefly, and Vitara applications, including California emissions vehicles where noted.

This part cross-references Bosch 13041 and Delphi ES20111 for the same application.

What This Oxygen Sensor Addresses

  • Check engine light related to oxygen sensor performance
  • Incorrect downstream exhaust readings
  • Emissions test failures tied to sensor output
  • Reduced catalytic converter monitoring accuracy
  • Fuel control issues caused by aging sensor response

Installation Notes and Quality Assurance

Verify the vehicle year, make, model, and emissions configuration before installation, especially on California emissions applications. Confirm downstream sensor location and compare the connector and harness routing to the original unit before replacement. Spectra Premium states that its engineering, manufacturing technology, and quality control processes are used to meet or exceed original equipment performance standards for replacement oxygen sensors.

The OS5206 is a practical OE-style replacement for downstream sensor service on the listed Chevrolet Metro, Suzuki Swift, Pontiac Firefly, Geo Metro, Chevrolet Tracker, and Suzuki Vitara applications.
