Denso OE Style Oxygen Sensor 234-3106
Denso 234-3106 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 upstream left position on the 2001-2002 Nissan Pathfinder and 2002-2003 INFINITI QX4, with a first-time fit that supports proper exhaust feedback and engine management.
Key Features
- Heated oxygen sensor for faster operating response
- Specific-fit design for direct replacement
- 3-wire configuration with male connector
- Threaded mounting type with 0.708 in. thread diameter
- 36.02 in. wiring harness length for application-specific routing
- OE Style construction for select Nissan Pathfinder and INFINITI QX4 models
OE Style Construction
Denso’s OE Style line focuses on exact replacement fit and factory-style performance. The sensor uses precision-built components and an aluminum oxide trap layer that helps protect the ceramic element from silicone and lead contamination, supporting stable signal output and long service life. This Denso oxygen sensor 234-3106 is a direct choice for drivers servicing a 2001-2002 Nissan Pathfinder or 2002-2003 INFINITI QX4 upstream left sensor location.
This part cross-references NTK 24528 and Bosch 13224 for the same application.
Common Uses
- Replacing a failed upstream left oxygen sensor
- Addressing check engine light concerns tied to oxygen sensor performance
- Restoring air-fuel feedback for engine control
- Correcting poor fuel economy caused by inaccurate exhaust readings
- Resolving drivability issues related to slow or inconsistent sensor response
Installation Notes
Verify the upstream left position before installation and confirm connector style, thread size, and harness length against the original sensor. This Denso 234-3106 uses a threaded mount and a 3-wire male connector, so matching the factory configuration is important for proper routing and secure installation. For best results, inspect the exhaust bung threads and wiring path before final tightening.
Quality Assurance
Denso manufactures and tests this oxygen sensor to OE standards for consistent fit and function. The OE-style design is intended to deliver the correct part and the correct fit for the listed Nissan Pathfinder and INFINITI QX4 applications.
