What It Helps Address

• Faulty air/fuel ratio sensor readings
• Check engine light concerns related to sensor performance
• Incorrect fuel control caused by a worn upstream sensor
• Emissions test failures tied to sensor response issues
• Driveability problems from inaccurate exhaust feedback

Installation Notes

Verify the connector style, thread size, and harness length before installation. This sensor is application-specific and should be matched to the exact vehicle, engine, and emissions configuration listed in the fitment data. Confirm the correct upstream position and bank/sensor location for the vehicle before replacement.

Quality Assurance

NTK is part of the NGK family of products and is a major original equipment oxygen sensor manufacturer. Each sensor is extensively tested during production to help ensure quality and reliability that meet or exceed OE specifications.
