NTK 24794 Oxygen Sensor - Downstream Rear

Direct-Fit Oxygen Sensor for Lexus and Toyota

NTK oxygen sensor 24794 is a direct-fit, specific-application replacement for select Lexus and Toyota models. It uses a heated, threaded design with a 4-wire configuration and 25.5-inch harness length for a factory-style service part.

Key Features

• Direct-fit, specific-application oxygen sensor
• Heated sensor design for stable signal performance
• Threaded mounting with 18 mm thread diameter
• 4-wire construction with 25.5-inch harness length
• Original equipment equivalent design for downstream rear service

Detailed Description

NTK 24794 is built for downstream rear oxygen sensor replacement on compatible Lexus RX350, RX350L, RX450h, RX450hL, and Toyota Highlander applications. As part of NTK's Direct Fit Oxygen Sensor line, it is engineered for specific vehicle coverage and factory-style installation, making it a practical choice when replacing a worn or failed sensor on these Lexus and Toyota platforms. Part number 24794 is also referenced by OE-style cross numbers 894650E220 and 894650E230.

NTK draws on its role as a major oxygen sensor manufacturer and uses controlled ceramic technology, manufacturing testing, and OE-focused application coverage to deliver fit, form, and function that align with original equipment requirements. The heated sensor design and threaded mount support accurate exhaust feedback in the downstream rear location.

What It Is Used For

• Replacing a failed downstream rear oxygen sensor
• Addressing check engine light concerns related to sensor performance
• Restoring exhaust feedback for emissions system monitoring
• Correcting drivability issues caused by inaccurate oxygen readings
• Servicing factory-style sensor applications on Lexus and Toyota vehicles

Installation Notes and Tips

Verify the connector, wire count, thread diameter, and harness length before installation. This sensor uses a threaded mounting style and is intended for specific-fit applications, so confirm the vehicle match and downstream rear position before ordering. Follow the service procedure for the exhaust system and apply proper torque during installation.

Quality Assurance

NTK tests these oxygen sensors during manufacturing to help ensure quality and reliability that meet or exceed OE specifications. The brand's OE-supplier background and application-specific design support consistent performance in emissions control service.
