Bosch 18167 Oxygen Sensor - Upstream, Upstream Left or Upstream Right

Bosch Wideband Oxygen Sensor for OE Fitment

Bosch Validated Oxygen Sensor 18167 is a specific-fit wideband air-fuel ratio sensor built for precise upstream mixture monitoring. It delivers continuous lambda measurement so the engine control module can manage fueling with the detail modern Ford and Lincoln applications require.

Key Features

• Wideband A/F oxygen sensor for accurate air-fuel ratio feedback across the full lambda range
• Heated design for faster sensor warm-up and stable operation
• Specific-fit replacement with included wiring harness
• 5-wire sensor design with 6 terminals and rectangular connector
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Steel finish and metal housing for durable underhood service
• Overall length: 16.5 in; sealing surface to connector end: 15.4 in

Product Details

Bosch 18167 is part of the Bosch Validated Oxygen Sensor line, which focuses on OE-style replacement coverage for modern emission-control systems. Bosch pioneered the wideband planar pump-cell design used in current engine management strategies, and this sensor follows that architecture for upstream air-fuel monitoring on applications such as the 2015-2018 Ford Edge, 2016-2018 Ford Explorer, 2016-2019 Ford Taurus, and 2017-2020 Lincoln Continental. It also fits select Ford Transit, E-350 Super Duty, Mustang, Flex, and Lincoln MKX/MKT/MKS applications listed below.

This part cross-references Ford FB5Z9F472A for the same application.

What It Helps Address

• Check engine lights related to oxygen sensor performance
• Incorrect fuel trim readings from a slow or inaccurate upstream sensor
• Rough idle, hesitation, or drivability issues tied to air-fuel feedback
• Higher emissions caused by poor mixture control
• Reduced fuel economy from faulty lambda measurement

Installation Notes and Tips

Confirm the connector shape, terminal count, and harness length before installation. This is a threaded upstream wideband sensor, so use the correct oxygen sensor socket and follow the vehicle service procedure for routing and connector placement. Verify the application by year, make, model, and position before replacing the original sensor.

Quality Assurance

Bosch supplies this oxygen sensor as a validated aftermarket replacement backed by more than five decades of OE development. The design reflects Bosch’s long-standing work in wideband sensor technology and modern emission-control calibration.
