Bosch 18224 Oxygen Sensor - Upstream

Bosch OE Quality Oxygen Sensor 18224

Bosch 18224 is a wideband air-fuel oxygen sensor built for precise mixture feedback in modern engine management systems. It is a specific-fit, heated upstream sensor with a 4-wire blade terminal design and included wiring harness for direct replacement service on select Nissan applications.

Key Features

• Wideband A/F oxygen sensor for continuous air-fuel ratio measurement across the full lambda range
• Heated design for faster sensor activity and stable operation during cold starts
• Specific-fit replacement with rectangle male connector and 4-wire configuration
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Metal housing and ceramic sensor construction for OE-style durability
• Wiring harness included for service replacement

Product Details

This Bosch OE Quality Oxygen Sensor is engineered for upstream exhaust monitoring where the ECU needs detailed feedback to manage fuel delivery and emissions control. Bosch pioneered the wideband A/F sensor design, and this part number 18224 follows that OE development with fast light-off, optimized heater control, and robust construction for consistent readings under changing load and temperature conditions. It is a direct-fit oxygen sensor for 2017-2025 Nissan Sentra, upstream, and 2015-2017 Nissan Juke, upstream. This part cross-references Nissan 22693BV80A and 226936LB0A for the same application.

What It Helps Address

• Check engine light related to upstream oxygen sensor performance
• Incorrect air-fuel ratio readings from a worn wideband sensor
• Poor fuel economy caused by inaccurate exhaust feedback
• Rough idle, hesitation, or drivability issues tied to mixture control
• Elevated emissions from delayed or unstable sensor response

Installation Notes

Verify the connector shape, wire count, thread size, and upstream location before installation. Bosch 18224 uses a threaded mount with a 18 mm thread diameter and 4-wire harness layout, so it should be matched to the original sensor configuration on the vehicle. For best results, inspect the harness routing and exhaust threads before fitting the new sensor.

Quality Assurance

Bosch supplies OE-proven oxygen sensor technology developed over decades of engine management experience. Part number 18224 is built to the same standard expected for modern wideband sensor applications and is intended for direct replacement service on the listed Nissan Sentra and Nissan Juke models.
