Bosch 17468 Oxygen Sensor - Upstream or Upstream Right

Bosch Wideband OE Oxygen Sensor

Bosch 17468 is an Actual OE Oxygen Sensor built as a wideband air-fuel sensor for precise mixture feedback to the ECU. It is a specific-fit, heated replacement with a 5-wire harness and 6-terminal blade connection for direct service on select Ford and Lincoln applications.

The Bosch Actual OE Oxygen Sensor line focuses on OE-style accuracy and durability for modern engine management systems. Bosch pioneered the wideband planar pump-cell design used in current low-emission technology, and this sensor follows that OE development with fast light-off, controlled heater performance, and a robust ceramic construction.

Key Features

• Wideband A/F oxygen sensor for continuous air-fuel ratio measurement
• Heated design for faster sensor response during cold starts
• Specific-fit replacement with included wiring harness
• 5-wire configuration with 6-terminal blade connection
• Threaded mounting, 18 mm thread size, 22 mm hex size
• Metal housing with oblong male connector
• Overall length: 26.4 in; sealing surface to connector end: 25.2 in

Detailed Description

Bosch part number 17468 is engineered for vehicles that rely on a wideband sensor to monitor the air-fuel ratio across the full lambda range. That detailed signal helps the engine control module manage fueling more precisely than a traditional switching sensor, which is important for drivability, fuel economy, and emissions control. This Bosch 17468 sensor is a direct replacement for upstream locations on select Ford EcoSport, Ford Expedition, Ford F-150, Ford Focus, and Lincoln Navigator applications.

This part cross-references Bosch 17468 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings from a worn upstream sensor
• Rough idle, hesitation, or inconsistent throttle response tied to sensor feedback
• Reduced fuel efficiency caused by inaccurate mixture control
• Emissions test failures linked to faulty wideband sensor output

Installation Notes and Tips

Install Bosch 17468 in the confirmed upstream position only. Verify the 18 mm thread size, 22 mm hex size, 5-wire layout, and oblong male connector before installation. Because this is a specific-fit sensor, compare the harness length and connector style to the original part on the vehicle before final assembly. Use proper oxygen sensor service tools and follow the vehicle manufacturer’s torque and routing specifications.

Quality Assurance

Bosch backs this Actual OE Oxygen Sensor with more than five decades of OE development experience. The wideband design, heater control, and ceramic construction reflect Bosch’s OE-focused engineering for modern Ford and Lincoln engine management systems.
