Bosch Actual OE Oxygen Sensor 16017
Bosch 16017 is a direct-fit, heated narrow-band oxygen sensor for precise air-fuel-ratio feedback to the ECU. It supports stable closed-loop fuel control and emissions performance for specific applications, including the downstream left sensor position on select Cadillac CTS, Cadillac STS, and Chevrolet Camaro models.
Key Features
- Direct-fit oxygen sensor with threaded mounting
- Heated narrow-band design for faster closed-loop operation
- 4-wire harness with rectangular male connector
- Steel-finish metal housing for high-temperature service
- 22 mm hex size and 18 mm thread diameter
- Wiring harness included with 10.6 in length
- Specific fit for confirmed vehicle applications
Product Details
As part of Bosch Actual OE Oxygen Sensor line, part number 16017 reflects Bosch’s OE development in switching-type oxygen sensing. Bosch uses ceramic sensing elements, controlled heater operation, and heat-resistant materials to maintain accurate lambda feedback under demanding thermal and vibration conditions. This Bosch oxygen sensor 16017 is built for direct replacement service where the original sensor location and connector style must match the vehicle harness.
Compatible With 2008-2011 Cadillac CTS, downstream left; 2008-2011 Cadillac STS, downstream left; and 2010-2011 Chevrolet Camaro, downstream left. This part cross-references 12601266 and 12616202 for the same application.
What It Helps Address
- Check engine light related to oxygen sensor performance
- Incorrect air-fuel ratio feedback to the ECU
- Delayed closed-loop fuel control after startup
- Rough idle or drivability issues tied to sensor signal degradation
- Emissions test failures caused by a worn downstream sensor
Installation Notes and Tips
Verify the downstream left location, connector shape, wire count, and thread size before installation. Use the existing threaded mounting point and confirm the harness routing matches the original sensor path. Because this is a specific-fit Bosch oxygen sensor, it should be matched to the exact vehicle application listed above, including the Cadillac CTS, Cadillac STS, and Chevrolet Camaro fitments.
Quality Assurance
Bosch has more than five decades of OE oxygen sensor development and supplies aftermarket sensors built to OE-proven standards. The Bosch Actual OE Oxygen Sensor 16017 is engineered for consistent signal accuracy and durable operation in demanding exhaust conditions.
