Product Details

Denso 234-5152 is manufactured and tested to OE standards for precise replacement performance. The OE Style line focuses on first-time fit and correct application matching, which is important for upstream air/fuel ratio sensor service where accurate exhaust feedback affects engine management. This part cross-references NTK 24373 for the same application.

Compatible With 2013-2017 Honda Accord, upstream, and 2014 Acura RLX, upstream. It also fits 2016-2020 Acura RLX, upstream. Use Denso 234-5152 when replacing a worn or failing upstream sensor on these vehicles, including Honda Accord and Acura RLX applications.

Common Replacement Reasons

• Check engine light related to air/fuel sensor performance
• Rough idle or inconsistent fuel control feedback
• Reduced fuel economy from inaccurate sensor readings
• Emissions test failure tied to upstream sensor faults
• Slow sensor response or heater circuit issues

Installation Notes

Verify the connector style, wire count, and thread diameter before installation. This is a specific-fit upstream sensor, so confirm the vehicle year, make, model, and position against the listed applications before ordering. For best results, inspect the harness routing and connector condition during replacement.

Quality Assurance
