Product Details
Bosch 16193 is built as a standard replacement oxygen sensor for the downstream location on 2016-2018 Hyundai Tucson models. Bosch’s Actual OE Oxygen Sensor line draws on decades of OE sensor development, using ceramic sensing elements and controlled heater operation to improve response time and maintain accurate lambda feedback under changing exhaust temperatures. This part cross-references Monroe Shocks & Struts (e.g., 392102ETL2, 392102ETL4) for the same application.
What This Sensor Helps Address
- Check engine light related to oxygen sensor performance
- Incorrect air-fuel ratio feedback to the ECU
- Slow sensor response during closed-loop operation
- Emissions test failures tied to downstream sensor faults
- Rough combustion control caused by degraded sensor output
Installation Notes
Fits 2016-2018 Hyundai Tucson, downstream. Verify the connector shape, 4-wire layout, and threaded mounting style before installation. The sensor uses an 18 mm thread diameter and 22 mm hex size, so the correct oxygen sensor socket or wrench is recommended. Confirm the harness routing and connector location match the original part before final tightening.
Quality Assurance
Bosch manufactures this oxygen sensor to OE-level specifications using durable materials and heater control strategies developed for demanding exhaust environments. Bosch’s long history in oxygen sensor engineering supports consistent signal accuracy and dependable operation in normal service conditions.
