Denso OE Style Oxygen Sensor 234-4715
Denso 234-4715 is a specific-fit heated oxygen sensor built to OE-style standards for accurate replacement on select Nissan and Infiniti applications. It is engineered for the 1996 Infiniti Q45 downstream right position and the 1996 Nissan 300ZX downstream position, with the right connector, thread size, and harness length for a direct-fit service job.
Key Features
- Heated oxygen sensor with specific fitment for select 1996 Nissan and Infiniti vehicles
- OE Style replacement from Denso for factory-style fit and function
- 4-wire design with male connector
- Threaded mounting with 0.708 in. thread diameter
- 28.74 in. wiring harness length for application-specific routing
- Aluminum oxide trap layer helps protect the sensing element from silicone and lead contamination
Product Details
Denso OE Style part number 234-4715 is built for direct replacement in emission control systems where precise sensor feedback matters. As a heated oxygen sensor, it helps the engine control module monitor exhaust oxygen content more quickly after startup and during normal operation. This supports proper air-fuel control, stable drivability, and efficient engine operation on the 1996 Infiniti Q45 downstream right and 1996 Nissan 300ZX downstream applications. This part cross-references Bosch 13268 and NTK 24550 for the same application.
Common Issues This Sensor Can Address
- Check engine light related to oxygen sensor performance
- Incorrect fuel trim readings from a worn downstream sensor
- Reduced fuel economy caused by inaccurate exhaust feedback
- Rough or inconsistent engine operation tied to aging emissions components
- Failed emissions inspection due to a faulty oxygen sensor
Installation Notes and Tips
Verify the connector style, wire count, thread diameter, and downstream position before installation. For fitment, use this part on 1996 Infiniti Q45, downstream right, and 1996 Nissan 300ZX, downstream. Inspect the exhaust bung threads and wiring routing before tightening the sensor to avoid cross-threading or harness strain.
Quality Assurance
Denso manufactures and tests this oxygen sensor to OE standards for consistent replacement performance and first-time fit. The sensor’s protective trap layer is designed to help reduce contamination-related wear and support long service life in demanding exhaust conditions.
