Bosch 16160 Oxygen Sensor - Upstream, Upstream Left or Upstream Right

Bosch Actual OE Wideband Oxygen Sensor

Bosch Part Number 16160 is an Actual OE wideband oxygen sensor built for precise air-fuel ratio measurement across the full lambda range. It provides the ECU with detailed feedback for accurate mixture control, helping maintain fuel efficiency, engine response, and lower emissions in demanding driving conditions.

Compatible With Hyundai Palisade, Kia Telluride, Lamborghini Huracan, Audi R8, Kia Sedona, Kia Cadenza, Kia Sorento, Hyundai Tucson, Kia Forte, Kia Forte5, and Hyundai Elantra GT applications listed below, this Bosch oxygen sensor uses a heated wide-band design with a threaded mount and included wiring harness for direct replacement service.

Key Features

• Wideband A/F oxygen sensor for continuous air-fuel ratio measurement
• Heated sensor design for faster light-off and stable operation
• Specific-fit replacement with oblong connector and male terminals
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Robust metal housing and ceramic sensor construction
• Wiring harness included for the listed application
• Bosch Actual OE Oxygen Sensor line backed by more than five decades of OE development

Product Details

Bosch 16160 is part of the Actual OE Oxygen Sensor line, a product line focused on OE-style fit, sensor accuracy, and durable construction for modern engine management systems. Bosch pioneered the wideband A/F oxygen sensor design used in current low-emission strategies, and this sensor follows that OE-proven approach with fast response, optimized heater control, and reliable performance through rapid load changes and thermal cycling. This part cross-references 4S0906262F for the same application.

Common Issues This Sensor Can Help Address

• Check engine light related to oxygen sensor or air-fuel ratio faults
• Incorrect fuel trim readings from a slow or inaccurate upstream sensor
• Rough idle, hesitation, or inconsistent throttle response
• Reduced fuel economy caused by poor mixture control
• Elevated emissions from an aging wideband sensor

Installation Notes and Tips

• Install in the upstream position specified for the vehicle application.
• Verify connector shape, terminal count, and harness length before installation.
• Use the correct 18 mm oxygen sensor socket or 22 mm hex tool for removal and tightening.
• Inspect the wiring route and keep the harness away from exhaust heat and moving components.
• Clear diagnostic trouble codes and confirm live data after installation.

Quality Assurance

Bosch supplies this oxygen sensor as an OE-grade replacement built to the same standards used in modern engine management systems. The design emphasizes measurement accuracy, heater control, and durability for long-term service in the listed Hyundai, Kia, Audi, and Lamborghini applications.
