Bosch 13505 Oxygen Sensor - Upstream or Upstream Right

Bosch Actual OE Oxygen Sensor 13505

Bosch 13505 is a specific-fit, narrow-band heated oxygen sensor for precise air-fuel ratio feedback to the ECU. It is built for stable combustion control, fast closed-loop response, and reliable emissions monitoring on select Nissan and INFINITI applications.

Fits 1999 INFINITI I30, upstream right without California Emission System. Fits 1999 Nissan Maxima, upstream right. Fits 1998 Nissan Maxima, upstream.

Key Features

• Actual OE Oxygen Sensor line from Bosch
• Narrow-band heated O2 sensor for direct ECU feedback
• Specific fit with 3-wire harness and oblong male connector
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Metal housing built for high-temperature and vibration exposure
• Wiring harness included with 27.4 in harness length
• Part number 13505 for accurate ordering and catalog matching

Product Details

Bosch 13505 uses a switching-type sensing element to measure oxygen content in the exhaust stream and send the signal needed for fuel control. Bosch’s OE development history includes early thimble-style sensors and later planar narrowband designs, which helped improve light-off speed, lambda accuracy, and closed-loop operation. This Bosch Actual OE Oxygen Sensor is built with ceramic sensing elements, controlled heating, and heat-resistant materials for consistent performance in demanding exhaust conditions.

For Nissan Maxima and INFINITI I30 service work, Bosch 13505 supports accurate sensor replacement where the original upstream sensor has aged, slowed, or drifted out of range. The part number 13505 is also useful when matching the correct OE-style replacement for the listed upstream right and upstream positions.

This part cross-references 226904L002 for the same application.

Common Issues It May Resolve

• Check engine light related to oxygen sensor performance
• Slow or inaccurate air-fuel ratio feedback
• Rough idle or unstable fuel control after sensor aging
• Failed emissions inspection tied to upstream O2 sensor faults
• Reduced closed-loop response during warm operation

Installation Notes

Confirm the sensor position, connector style, and thread size before installation. Bosch 13505 is a threaded, heated narrow-band sensor with a 3-wire harness and male connector, so the replacement should match the vehicle’s original configuration. Use proper oxygen sensor service tools and inspect the exhaust bung threads and wiring routing before final tightening.

Quality Assurance

Bosch supplies OE-developed oxygen sensors to the aftermarket using the same engineering approach that supports vehicle manufacturers. Bosch 13505 is part of the Actual OE Oxygen Sensor line, built for accurate signal output and durable operation in high-heat exhaust environments.
