Bosch OE Quality Oxygen Sensor 18272
Bosch 18272 is a specific-fit, narrow-band heated oxygen sensor built for precise air-fuel-ratio feedback to the ECU. It is engineered for upstream right applications on select Cadillac, Chevrolet, and GMC trucks and SUVs, including Escalade, Tahoe, Yukon, Silverado 1500, and Sierra 1500 coverage.
Key Features
- OE Quality Oxygen Sensor from Bosch
- Narrow-band heated oxygen sensor design for closed-loop fuel control
- Specific fit with threaded mounting
- 4-wire configuration with blade terminals and oblong connector
- Wiring harness included for direct replacement use
- Metal housing with high-temperature-resistant construction
- 22 mm hex size and 18 mm thread diameter
- Part number 18272 for application matching and search accuracy
Product Details
Bosch OE Quality Oxygen Sensor 18272 uses a narrow-band heated sensing element to deliver stable signal feedback during warm-up and normal driving conditions. Bosch developed this sensor line from decades of OE oxygen sensor engineering, including planar narrowband designs that improve light-off speed, lambda accuracy, and closed-loop response. For drivers searching for an upstream right oxygen sensor for 2016-2020 Cadillac Escalade, 2016-2020 Chevrolet Tahoe, or 2016-2020 GMC Yukon applications, Bosch 18272 provides the OE-style replacement format needed for emission control service. This part cross-references 12666673 for the same application.
What It Helps Address
- Check engine light related to oxygen sensor performance
- Incorrect air-fuel ratio feedback to the ECU
- Rough idle or unstable combustion control
- Increased emissions from a slow or inaccurate upstream sensor
- Delayed closed-loop operation after startup
Installation Notes
Install Bosch 18272 in the upstream right position only where listed in the fitment data. Verify the 18 mm thread size, 22 mm hex, 4-wire connector layout, and oblong male connector before installation. Because this is a threaded sensor with a specific fit harness, confirm the vehicle connector and routing match the original sensor on the Cadillac Escalade, Chevrolet Silverado 1500, or GMC Sierra 1500 application.
Quality Assurance
Bosch draws on more than five decades of OE oxygen sensor development, supplying aftermarket sensors built to the same engineering standards used by vehicle manufacturers. The 18272 is part of Bosch’s OE Quality Oxygen Sensor line, focused on durable sensing performance under heat and vibration.
