What It Helps Address

• Faulty oxygen sensor readings that can trigger drivability concerns.
• Slow sensor response that affects air/fuel control.
• Check engine light conditions related to sensor performance.
• Replacement needs for threaded, heated sensor applications.
• OE-style service requirements on Lexus LS400 and Lexus SC400 models.

Installation Notes and Tips

Verify the connector, wire count, thread diameter, and harness length before installation. Confirm the listed position and bank/sensor callout for the vehicle application, since this part is specific-fit and not universal. Use the fitment notes to match the correct upstream location on Lexus LS400 and Lexus SC400 applications.

Quality Assurance

NTK manufactures oxygen sensors with OE application technology and extensive production testing to support quality and reliability that meets or exceeds OE specifications.
