Product Details
Denso 234-5084 is manufactured as an OE Style emission control sensor with the dimensions and connector layout needed for a first-time fit. The heated design helps the sensor reach operating temperature quickly, supporting stable air/fuel ratio feedback to the engine control system. This part is a specific-fit replacement, not a universal sensor, and it is intended for upstream placement on the listed Mercedes-Benz vehicles. If you are replacing a Mercedes-Benz Sprinter 2500 upstream air/fuel ratio sensor or servicing a Mercedes-Benz E350 upstream sensor, this Denso OE Style part provides the correct application match.
This part cross-references Bosch 17200 for the same application.
What It Helps Address
- Check engine light related to air/fuel ratio sensor faults
- Rough idle caused by inaccurate exhaust feedback
- Fuel trim issues from a slow or failing upstream sensor
- Emissions test failures tied to sensor performance
- Driveability concerns from incorrect air/fuel mixture control
Installation Notes
Verify the upstream sensor location before ordering and match the connector, wire count, and thread size to the original part. Inspect the harness routing and connector condition during replacement, and confirm the sensor is installed in the correct bank and position for the vehicle. For Mercedes-Benz Sprinter 2500, Sprinter 3500, Sprinter 3500XD, and E350 applications, use the vehicle identification details to confirm exact fitment before installation.
Quality Assurance
Denso manufactures this OE Style sensor to strict original-equipment standards and tests each component for replacement accuracy and fit. The part number 234-5084 is built for direct replacement service on the listed Mercedes-Benz applications.
