Bosch 16682 Oxygen Sensor - Downstream, Downstream Right or Upstream

Bosch Actual OE Oxygen Sensor 16682

Bosch 16682 is a narrow-band heated oxygen sensor built for precise air-fuel ratio feedback to the ECU. It supports stable combustion control and emissions management in specific Volvo and Saab applications, including downstream and upstream locations.

Key Features

• Actual OE Oxygen Sensor from Bosch Actual OE Oxygen Sensor line
• Narrow-band heated design for closed-loop fuel control
• Specific fit with threaded mounting and 18 mm thread size
• 4-wire harness with rectangular male connector
• Steel finish with metal housing for underbody durability
• Wiring harness included; harness length measures 27 in
• Overall length: 30.3 in; sealing surface to connector end: 29.1 in
• Hex size: 22 mm

Product Details

This Bosch oxygen sensor uses advanced ceramic sensing elements and controlled heater operation to deliver fast light-off and accurate lambda feedback across changing exhaust temperatures. Bosch developed this sensor family from its original OE oxygen sensor designs and continues to supply aftermarket parts built to OE specifications. Bosch 16682 is a direct replacement for specific Volvo C30, C70, S40, S60, S80, V50, V70, XC70, XC90 and Saab 9-5, 9-3 applications where precise downstream or upstream signal control is required.

This part cross-references 4570909 and 9487146 for the same application.

What It Helps Address

• Check engine light caused by oxygen sensor signal faults
• Incorrect air-fuel ratio readings at the ECU
• Slow closed-loop response after warm-up
• Emissions test failures related to sensor performance
• Rough combustion control from degraded upstream or downstream sensing

Installation Notes

Verify the sensor position, connector shape, wire count, and thread size before installation. This Bosch 16682 uses a threaded mount with a 22 mm hex and a 4-wire rectangular male connector, so the replacement should match the original sensor configuration. Confirm the vehicle-specific location listed in fitment, including downstream, upstream, or downstream right applications, before ordering.
