Detailed Description
Compatible with 1999-2003 Lexus RX300, downstream; 2001-2003 Toyota Highlander, downstream; and 1993-1998 Toyota Supra, downstream, with 1993-1995 Toyota Supra coverage limited to California emissions vehicles only. The Spectra OS5287 oxygen sensor is used to monitor exhaust oxygen content after the catalytic converter, supporting proper feedback for the vehicle’s emission control strategy. If you are replacing a worn downstream sensor on a Toyota Supra, Toyota Highlander, or Lexus RX300, this part number provides a direct application match for the listed vehicles.
What It Helps Address
- Check engine light related to downstream oxygen sensor faults
- Slow or inaccurate exhaust oxygen readings
- Emission test failures tied to sensor performance
- Rougher fuel control caused by a degraded sensor signal
- Replacement needs on high-mileage Toyota and Lexus emission systems
Installation Notes and Tips
Verify the vehicle year, model, and emissions configuration before ordering, especially for 1993-1995 Toyota Supra California emissions vehicles. Confirm the downstream sensor location on the exhaust system and compare the connector and harness routing to the original part before installation. Use the vehicle service manual for torque and wiring procedures.
