OE Sensor Design and Performance
As part of Bosch’s Actual OE Oxygen Sensor line, this sensor reflects Bosch’s long-running OE development in switching-type oxygen sensing. The narrow-band heated design uses advanced ceramic elements and heater control to deliver stable signal response, quicker closed-loop operation, and accurate lambda feedback across changing exhaust temperatures. Bosch 18001 is built for the demands of daily driving and emission-control monitoring on the Nissan Frontier and Nissan Xterra.
This part cross-references Nissan 22690EK800 for the same application.
Vehicle Fitment
- Fits 2004 Nissan Frontier, upstream right.
- Fits 2004 Nissan Xterra, upstream right.
Common Issues This Sensor Can Address
- Check engine light related to oxygen sensor performance
- Delayed or unstable closed-loop fuel control
- Incorrect air-fuel ratio feedback to the ECU
- Emission test failures tied to sensor response issues
- Rough combustion control caused by a worn upstream sensor
Installation Notes
Confirm the upstream right location before ordering and match the threaded mounting, connector shape, and harness length to the original sensor. Use the 18 mm thread size and 22 mm hex specification to select the correct removal tool, and inspect the connector and wiring routing before installation. For best results, clear diagnostic trouble codes after replacement and verify sensor operation during a warm engine cycle.
Quality Assurance
Bosch backs this oxygen sensor with OE-level engineering developed from decades of original equipment experience. The Bosch 18001 is built with high-temperature-resistant materials and heater control intended to maintain consistent signal quality under thermal and vibration load.
