Product Details
The Denso OE Style line is built around original-equipment replacement standards, with attention to fit, connector style, and sensor performance. Part number 234-4074 uses Denso’s aluminum oxide trap layer to help protect the ceramic sensing element from silicone and lead contamination, supporting stable engine management and consistent emissions feedback. This part cross-references Bosch 15228 and NTK 24289 for the same application. It is a direct-fit oxygen sensor for 1998-2003 Honda Civic upstream locations, and it is also referenced by Honda OE numbers in the same application family.
Common Issues This Sensor Can Address
- Check engine light related to oxygen sensor performance
- Incorrect air-fuel ratio feedback to the engine control system
- Reduced fuel economy caused by a slow or inaccurate upstream sensor
- Emissions test failures tied to sensor response problems
- Rough idle or drivability concerns linked to faulty exhaust feedback
Installation Notes and Tips
Verify the upstream position and connector match before installation. Confirm thread diameter, wire count, and harness length against the original sensor on your Honda Civic. Because this is a threaded, specific-fit sensor, proper routing and secure connector engagement are important for reliable operation.
Quality Assurance
Denso manufactures and tests this oxygen sensor to OE standards for replacement accuracy and consistent performance. The OE Style design is intended to provide the correct fit and sensor configuration for the listed Honda Civic applications.
