Bosch 16513 Oxygen Sensor - Downstream, Downstream Left or Downstream Right

Bosch OE Oxygen Sensor for Nissan and Infiniti

Bosch Actual OE Oxygen Sensor 16513 is a narrow-band heated sensor built for precise air-fuel ratio feedback to the ECU. It supports stable combustion control and emissions management for downstream applications on select Nissan, INFINITI, and Suzuki vehicles.

With OE-style construction, a threaded mount, 4-wire harness, and a square male connector, this Bosch oxygen sensor is a direct-fit replacement for many downstream left and downstream right locations. It is a practical choice for Nissan Frontier, Pathfinder, Armada, TITAN, Xterra, NV-series vans, and related applications where accurate lambda feedback matters.

Product Details

Bosch developed its oxygen sensor technology over decades of OE engineering, starting with early sensor designs and later advancing to planar narrowband construction for faster light-off and quicker closed-loop operation. Bosch 16513 uses a heated narrow-band sensor element and optimized heater control to deliver consistent signal response under changing exhaust temperatures. This helps the ECU maintain the correct air-fuel mixture during downstream monitoring on vehicles such as the Nissan Frontier, Nissan Pathfinder, Nissan Armada, Nissan TITAN, and INFINITI QX56.

This part cross-references 226A0EA200 and 226A08U300 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect downstream air-fuel feedback readings
• Slow sensor response during closed-loop operation
• Emissions test failures tied to sensor degradation
• Rough combustion control caused by aging sensor elements

Installation Notes and Tips

Confirm the connector shape, wire count, and downstream position before installation. This Bosch 16513 sensor uses a threaded mount with an 18 mm thread size and 22 mm hex, so the exhaust bung and service tool must match the sensor design. Verify the vehicle application carefully for downstream left or downstream right placement on Nissan and INFINITI models, including Frontier, Pathfinder, Armada, TITAN, Xterra, NV1500, NV2500, NV3500, Sentra, and Suzuki Equator.
