What This Sensor Helps Address

• Check engine light concerns related to oxygen sensor performance
• Incorrect air/fuel ratio readings from a worn upstream sensor
• Slow or unstable sensor response during closed-loop operation
• Emissions test failures tied to sensor degradation
• Replacement needs for Toyota Camry, Celica, Pickup, 4Runner, Van, Starlet, and Corolla applications

Installation Notes and Tips

Verify the vehicle year, engine configuration, and sensor position before ordering. This NTK 24611 oxygen sensor is a specific-fit part, so confirm the upstream location and thread/mounting style against the original sensor. For Toyota Camry, Celica, and related applications, compare the connector, harness length, and mounting style to the removed unit before installation.

Quality Assurance

NTK is a major original equipment oxygen sensor manufacturer, and this sensor is produced with manufacturing controls and testing intended to meet OE-level specifications for quality and reliability.
