Bosch 13117 Oxygen Sensor - Upstream, Upstream Left or Upstream Right

Bosch OE Oxygen Sensor for Ford and Mazda

Bosch 13117 is an Actual OE Oxygen Sensor built as a narrow-band heated replacement for specific Ford, Lincoln, Mercury, and Mazda applications. It measures air-fuel ratio for the ECU so the engine can maintain stable combustion control and emissions performance across changing operating conditions.

Use Bosch 13117 when you need a direct-fit upstream oxygen sensor for vehicles such as the Ford Ranger, Ford Explorer, Ford Expedition, Lincoln Navigator, Mercury Mountaineer, and Mazda B3000/B4000.

Key Features

• Specific-fit, threaded oxygen sensor for direct application matching
• Narrow-band heated design for quicker closed-loop operation
• 4-wire configuration with blade terminals and round connector
• Metal housing with high-temperature-resistant construction
• 18 mm thread size and 22 mm hex size
• Wiring harness included for the listed applications
• Overall length: 16.6 in; harness length: 13.3 in

Product Details

Bosch developed its oxygen sensor technology through decades of OE engineering, beginning with early sensor designs and later advancing to planar narrowband construction for faster light-off and improved lambda accuracy. Bosch 13117 uses a heated narrow-band sensor element to deliver precise feedback to the ECU, helping the engine respond correctly during warm-up, idle, cruise, and load changes. This Bosch Actual OE Oxygen Sensor is a direct replacement for upstream locations on selected Ford Ranger, Ford Explorer, Ford Expedition, Lincoln Navigator, Mercury Mountaineer, and Mazda B4000/B3000 models.

This part cross-references ZZR218861 for the same application. Bosch 13117 is built for vehicles that require an upstream, threaded, heated narrow-band oxygen sensor with a 4-wire harness and male connector interface.

What It Helps Fix

• Check engine light related to oxygen sensor performance
• Rough idle caused by inaccurate air-fuel feedback
• Reduced fuel economy from incorrect mixture control
• Failed emissions testing tied to sensor response issues
• Slow closed-loop transition after cold start

Installation Notes and Tips

Confirm the sensor position before ordering, since this part is listed for upstream left, upstream right, and upstream applications depending on vehicle and engine configuration. Verify the 18 mm thread diameter, 22 mm hex size, 4-wire layout, and round connector match the original sensor before installation. For best results, inspect the harness routing and connector condition during replacement, especially on Ford Ranger and Ford Explorer applications where heat exposure can affect the original wiring.
