What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture readings
• Reduced fuel economy caused by a failing upstream sensor
• Emissions test failures tied to sensor response issues
• Rough idle or drivability concerns linked to inaccurate exhaust feedback

Installation Notes and Tips

Confirm the vehicle year, make, model, and sensor position before installation. This sensor is threaded and specific fit, so verify the upstream Bank 1 Sensor 1 location and match the 4-wire harness length to the original routing. Inspect the connector, exhaust threads, and surrounding wiring before installation to avoid repeat faults.

Quality Assurance

NTK manufactures oxygen sensors with OE-focused engineering and extensive production testing to meet or exceed original equipment specifications. The brand’s Direct Fit Oxygen Sensor line is built to support accurate replacement selection for emission control service.
