Bosch 16736 Oxygen Sensor - Downstream

Bosch Actual OE Oxygen Sensor 16736

Bosch 16736 is a specific-fit, narrow-band heated oxygen sensor built for downstream applications on select Chevrolet models. It uses a 4-wire, pin-terminal design with an oblong female connector and included wiring harness to deliver accurate air-fuel-ratio feedback to the ECU.

As part of Bosch Actual OE Oxygen Sensor line, this sensor reflects Bosch’s long OE development history in switching-type O2 sensing. The design uses a ceramic sensing element, controlled heater operation, and high-temperature materials to support stable closed-loop operation under demanding heat and vibration conditions.

Key Features

• Specific-fit Bosch oxygen sensor for downstream placement
• Narrow-band heated sensor type for precise switching-type signal output
• 4-wire construction with pin terminals and female connector
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Steel finish with metal housing for underbody durability
• Wiring harness included for direct replacement use
• Part number 16736 for easy lookup and ordering

Detailed Description

Bosch 16736 is engineered for vehicles that use a downstream narrow-band oxygen sensor to monitor exhaust oxygen content after the catalytic converter. It is a direct replacement for 2011-2015 Chevrolet Cruze, 2012-2020 Chevrolet Sonic, and 2016 Chevrolet Cruze Limited in the downstream position. If you are searching for a downstream oxygen sensor for Chevrolet Cruze or Chevrolet Sonic, Bosch 16736 provides the OE-style fit and signal behavior expected in these applications. This part number 16736 is also a practical reference when comparing Bosch oxygen sensor replacement options for these vehicles.

Bosch’s Actual OE Oxygen Sensor line focuses on accurate lambda measurement, fast heater response, and consistent operation across changing engine loads. That makes this sensor a strong match for drivers addressing emissions-related faults, drivability concerns, or aging sensor performance on Cruze and Sonic models.

This part cross-references 55572216 and 55574136 for the same application.

Common Issues This Sensor Can Address

• Check engine light related to downstream oxygen sensor performance
• Incorrect exhaust oxygen readings reported to the ECU
• Rough or unstable closed-loop fuel control
• Emissions test failures tied to sensor degradation
• Slow sensor response from heat cycling and age

Installation Notes and Tips

Verify the downstream location before ordering and match the connector, thread size, and harness length to the original sensor. The threaded 18 mm design installs into the exhaust stream, so proper removal tools and anti-seize practices should follow vehicle service procedures. Confirm the connector routing and harness path on the Chevrolet Cruze, Chevrolet Cruze Limited, or Chevrolet Sonic before final installation.

Quality Assurance

Bosch has supplied oxygen sensor technology to vehicle manufacturers for decades, and the Actual OE Oxygen Sensor line is built around OE-proven sensing and heater control principles. Bosch 16736 is a standard replacement sensor designed to meet the fit and function expected for the listed downstream applications.
