Bosch 16167 Oxygen Sensor - Upstream or Upstream Right

Bosch Actual OE Oxygen Sensor for Mercedes-Benz and Chrysler

Bosch 16167 is a narrow-band heated oxygen sensor built for specific upstream applications on select Mercedes-Benz and Chrysler vehicles. It provides precise air-fuel-ratio feedback to the ECU, helping maintain stable combustion control and lower emissions across changing operating conditions.

As part of Bosch’s Actual OE Oxygen Sensor line, this replacement follows OE-style design and calibration for direct-fit service on the listed vehicles, including Mercedes-Benz C240, C320, CLK500, CLK55 AMG, SL500, SL55 AMG, and Chrysler Crossfire applications.

Key Features

• Specific-fit Bosch oxygen sensor for confirmed upstream applications
• Narrow-band heated design for faster closed-loop operation
• Advanced ceramic sensing element for accurate lambda feedback
• Optimized heater control for quicker light-off
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• 4-wire harness with round female connector
• Wiring harness included for direct replacement service
• Steel-finish metal housing for high-temperature and vibration resistance

Product Details

Bosch 16167 uses the brand’s OE development experience in switching-type oxygen sensor technology to deliver stable signal output for engine management systems. The sensor is designed for upstream placement on the listed Mercedes-Benz and Chrysler models, where accurate exhaust oxygen measurement is critical for fuel control, drivability, and emissions performance. This Bosch Actual OE Oxygen Sensor line reflects the same engineering approach used in OE supply, with durable materials and heater management suited to harsh thermal cycling.

This part cross-references URO 0015405017 and Chrysler 5099820AA for the same application.

Common Issues This Sensor Can Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture readings at the ECU
• Rough idle or unstable closed-loop fuel control
• Increased exhaust emissions from a failing upstream sensor
• Slow sensor response during warm-up or load changes

Verify connector shape, thread size, and sensor position before installation. The sensor uses a threaded mount, 4-wire configuration, and a round female connector with a 14.8-inch wiring harness length. Proper routing away from exhaust heat and secure connector engagement are important for reliable operation.

Quality Assurance

Bosch backs this oxygen sensor with more than five decades of OE development in emissions and engine-management sensing. The design uses high-temperature-resistant materials, ceramic sensing elements, and controlled heater operation to support consistent performance in demanding underhood conditions.
