Product Line Details

Bosch Universal Oxygen Sensor line combines OE-style sensing elements with a reusable connector solution. The SmartLink system is built for technicians who need a dependable way to adapt a universal O2 sensor to an existing harness while maintaining a secure, weather-resistant connection.

Detailed Description

Bosch part number 15735 is a standard replacement oxygen sensor for upstream and other listed positions where a narrow-band heated sensor is specified. It is engineered to deliver the same type of feedback used by the engine control module to manage fuel delivery and emissions performance. The threaded design, 18 mm thread size, and included wiring harness make it suitable for a wide range of import applications, including Nissan Altima, Maxima, Frontier, Xterra, and Infiniti I35, QX4, and G20 fitments listed in the catalog data.

This part cross-references 94460613500 for the same application.

What It Helps Address

• Check engine light caused by oxygen sensor circuit or response faults
• Rough idle or drivability issues tied to incorrect air-fuel feedback
• Failed emissions inspection related to sensor performance
• Damaged, shortened, or missing factory connector wiring
• Replacement needs on upstream sensor locations across older import vehicles

Installation Notes and Tips

• Verify the vehicle’s sensor position and connector style before installation.
• Use the Posi-Lock connector system to adapt the harness without soldering or crimping.
• Confirm thread size, hex size, and lead length match the original application.
• Inspect the exhaust bung and wiring route before tightening the sensor.
• Clear diagnostic trouble codes after installation and confirm closed-loop operation.

Quality Assurance

Bosch builds this universal oxygen sensor with the same zirconia ceramic element and heater design used in its OE applications, supporting consistent sensor response and dependable operation across the listed fitments.
