What It Helps Address

• Check engine light related to oxygen sensor performance
• Poor fuel economy caused by incorrect exhaust feedback
• Rough engine operation from inaccurate air-fuel readings
• Elevated exhaust emissions from a failing upstream sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

• Verify the exact position before ordering: Fits 1997-2000 Toyota Camry, upstream front or upstream rear; Fits 1997-2000 Toyota RAV4, upstream; Fits 1999-2000 Toyota Sienna, upstream front or upstream rear; Fits 1999-2000 Toyota Solara, upstream front or upstream rear; Fits 1997-1999 Toyota Avalon, upstream front or upstream rear; Fits 2001-2003 Toyota Highlander, upstream front or upstream rear; Fits 1999-2003 Lexus RX300, upstream front or upstream rear; Fits 1997-1999 Lexus ES300, upstream front or upstream rear; Fits 1999 Lexus ES300, upstream front or upstream rear.
• Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation.
• Confirm the threaded mounting location and connector style match the original sensor.
• Clear stored fault codes after repair and verify proper ECU feedback during a road test.
