NTK 24547 Oxygen Sensor - Downstream or Upstream

Direct Fit Oxygen Sensor for Toyota and Lexus

NTK Oxygen Sensor 24547 is a direct fit, heated oxygen sensor built for specific applications in Toyota and Lexus vehicles. It is engineered for OE-equivalent fit, form, and function, with a threaded mounting design and a 4-wire configuration for accurate exhaust feedback.

NTK’s Direct Fit Oxygen Sensor line focuses on application-specific coverage and ceramic sensor technology developed under the NGK family of products. For drivers servicing a Toyota Camry, Lexus IS300, or Lexus SC300, this sensor supports the original-style installation and signal performance expected from an OE replacement.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture feedback from a worn sensor
• Slow sensor response during closed-loop operation
• Emissions test failures tied to sensor degradation
• Rough idle or drivability issues caused by inaccurate exhaust readings

Installation Notes and Tips

Verify the sensor position before ordering, since this application covers both upstream and downstream locations on select vehicles. Confirm the 4-wire connector style, threaded mounting point, and harness length against the original sensor before installation. Use the vehicle’s service information for torque and routing details, and inspect the exhaust threads for damage or contamination before threading in the new sensor.
