NTK 24485 Oxygen Sensor - Downstream

Direct Fit Oxygen Sensor for Honda

This NTK direct fit oxygen sensor is built as a standard replacement for specific Honda applications. It uses a heated narrow-band design with a 4-wire, pin-terminal layout for closed-loop fuel control and OBDII monitoring.

• Specific-fit oxygen sensor for direct replacement service
• Heated narrow-band design for stable signal response
• 4-wire configuration with rectangular female connector
• Threaded screw-in mounting with M18 x 1.5 thread size
• Standard replacement part for emission control diagnostics

Fitment and Application

Compatible with downstream applications on the Honda CR-V and Honda Civic. Fits 2017-2022 Honda CR-V, downstream. Fits 2016-2021 Honda Civic, downstream. This part cross-references DENSO Auto Parts (e.g., 234-8027) for the same application.

As part of NTK’s Direct Fit Oxygen Sensor line, this sensor is engineered for specific applications rather than universal use. The line is focused on OE-style replacement coverage and application-specific sensor technology, which helps maintain the air-fuel feedback needed by the engine management system. Part number 24485 is also referenced as 24485 for ordering and catalog matching.

What It Helps Address

• Fault codes related to oxygen sensor performance
• Incorrect air-fuel ratio feedback to the ECU
• Reduced fuel economy caused by inaccurate sensor readings
• Emission system warnings tied to catalyst efficiency monitoring
• Driveability issues from delayed closed-loop response

Installation Notes and Quality

Install as a threaded screw-in sensor with the correct 22 mm wrench size and verify connector and harness routing before final installation. Confirm thread size, connector shape, and downstream placement against the vehicle application before replacement. NTK is a major OEM oxygen sensor supplier and uses in-house ceramic technology control from raw material through finished sensor production. Part number 24485 is supported by NTK’s OE application technology and direct-fit product strategy.
