Denso OE Style Oxygen Sensor 234-4430
Denso 234-4430 is an OE-style heated oxygen sensor built for precise replacement and consistent signal performance. It is a specific-fit sensor for downstream use on select Mitsubishi Lancer applications, including 2006 and 2007 models.
The Denso OE Style line focuses on exact fit and OE-level construction. This sensor uses a threaded mounting design, a female connector, four wires, and a 16.54-inch wiring harness length for a direct replacement layout on the correct application.
Key Features
- Heated oxygen sensor for downstream exhaust monitoring
- Specific-fit design for select Mitsubishi Lancer applications
- Threaded mounting type with 0.708-inch thread diameter
- Female connector with 4-wire configuration
- 16.54-inch wiring harness length
- OE Style replacement from Denso
OE Style Construction
Denso’s OE Style product line is built to match original equipment fit and function as closely as possible. The sensor is precision built for direct replacement, and its ceramic element protection uses an aluminum oxide trap layer to help shield the sensing element from silicone and lead contamination. That construction supports stable engine management feedback and long service life in the correct application.
This part cross-references Bosch 13830 for the same application.
Vehicle Fitment
- Fits 2007 Mitsubishi Lancer, downstream.
- Fits 2006 Mitsubishi Lancer, downstream, from 03/04/06.
Common Issues This Sensor Can Address
- Check engine light related to downstream oxygen sensor faults
- Incorrect exhaust oxygen readings affecting fuel control
- Reduced fuel economy caused by a failing sensor signal
- Emissions test failure tied to oxygen sensor performance
- Rough or inconsistent engine operation from inaccurate feedback
Installation Notes
Confirm the downstream location, connector style, wire count, and threaded mounting dimensions before installation. For 2006 Mitsubishi Lancer applications, verify the build date note of 03/04/06 to ensure correct fitment. Inspect the harness routing and connector condition during replacement so the new sensor installs cleanly and reaches the factory connection point.
Quality Assurance
Denso manufactures and tests this oxygen sensor to OE standards for fit, function, and durability. The OE-style design is intended to provide the right part and the right fit for the specified Mitsubishi Lancer applications.
