Bosch 17006 Oxygen Sensor - Upstream

Bosch Wideband OE Oxygen Sensor

Bosch 17006 is a specific-fit wideband air-fuel oxygen sensor for precise upstream mixture monitoring. It provides the ECU with continuous air-fuel ratio data across the full lambda range, helping maintain accurate fuel control in demanding driving conditions.

Key Features

• Wideband A/F oxygen sensor for detailed air-fuel ratio measurement
• Heated design for faster sensor warm-up and stable operation
• Specific-fit replacement with 5-wire harness and 6 terminals
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Rectangle male connector with included wiring harness
• Robust metal housing for OE-style durability

Product Details

As part of Bosch’s Actual OE Oxygen Sensor line, part number 17006 reflects Bosch’s long OE development history in engine management sensors. This wideband sensor uses a planar pump-cell design and optimized heater control to deliver fast response and accurate readings during load changes and thermal cycling. It is a direct replacement for upstream monitoring on 2011-2013 INFINITI QX56 and 2014 INFINITI QX80 models built through 07/2014. This part cross-references 226931LA0C for the same application.

Common Issues This Sensor Can Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings at the ECU
• Rough idle or inconsistent throttle response from faulty upstream sensing
• Reduced fuel economy caused by inaccurate mixture control
• Higher emissions from delayed or unstable sensor feedback

Installation Notes and Tips

Install Bosch 17006 in the upstream position only where specified by fitment. Confirm the 18 mm thread size, 6-terminal connector, and rectangle male plug before installation. Because this is a specific-fit sensor, compare the original connector, harness length, and mounting style to the vehicle’s existing sensor before replacement.

Quality Assurance

Bosch supplies OE-proven oxygen sensors backed by more than five decades of engine management development. The Bosch 17006 is built to the same standard expected for modern wideband emissions control on INFINITI QX56 and INFINITI QX80 applications.
