Denso OE Style Oxygen Sensor 234-3001
Denso 234-3001 is an OE Style heated oxygen sensor built for specific-fit replacement on select Ford, Lincoln, and Mercury applications. It is engineered for upstream locations and uses a threaded mounting design with a 3-wire male connector for direct replacement service.
Key Features
- Heated oxygen sensor for upstream exhaust monitoring
- Specific-fit design for direct replacement on listed vehicles
- 3-wire configuration with male connector
- Threaded mounting with 0.708 in. thread diameter
- 10.83 in. wiring harness length for application-specific routing
- OE Style construction for factory-type fit and function
OE Style Construction
Denso’s OE Style line is built to match original equipment requirements for fit, form, and function. This oxygen sensor uses precision-built components for exact replacement service, and the design includes an aluminum oxide trap layer that helps protect the ceramic element from silicone and lead contamination. That support helps maintain engine performance, fuel efficiency, and sensor durability in demanding exhaust conditions. This part cross-references Bosch 13913 for the same application.
