Detailed Description
The Denso 234-5719 is an OE Style air/fuel ratio sensor for the upstream position on the 2016, 2017, and 2018 Volkswagen Jetta. As an emission control sensor, it helps the engine management system monitor exhaust mixture data so the vehicle can maintain proper fuel control and emissions performance. This part number is also referenced as Volkswagen 04E906262EE and NTK 27040 for the same application.
Built as a specific-fit replacement, this Denso air/fuel ratio sensor is intended for buyers who need the correct connector, thread size, and harness length without modifying the vehicle harness. The Denso 234-5719 is a practical choice for Volkswagen Jetta upstream sensor service where OE-style fitment matters.
What This Sensor Helps Address
- Check engine light related to upstream air/fuel ratio sensor faults
- Incorrect fuel mixture readings from a failing sensor
- Rough idle or drivability issues tied to mixture control
- Emissions test failures caused by sensor performance problems
- Slow sensor response in the engine management system
Installation Notes and Tips
Confirm the vehicle is a 2016-2018 Volkswagen Jetta with the upstream sensor location before ordering. Match the connector style, wire count, and thread diameter to the original part, and inspect the exhaust bung threads before installation. Because this is a heated sensor, verify the electrical connector is fully seated and the harness is routed away from heat and moving components.
Quality Assurance
Denso manufactures and tests this OE Style sensor to strict original-equipment standards for replacement accuracy and fit. The 234-5719 is built for direct replacement service on the listed Volkswagen Jetta applications.
