Bosch 13228 Oxygen Sensor - Upstream Left or Upstream Right

Bosch Actual OE Oxygen Sensor 13228

Bosch 13228 is a specific-fit, narrow-band heated oxygen sensor built for precise air-fuel-ratio feedback to the ECU. It supports stable combustion control and emissions management for select Nissan and INFINITI applications, including upstream left and upstream right positions where listed.

Key Features

• Specific-fit Bosch Actual OE Oxygen Sensor for direct application matching
• Narrow-band heated design for faster closed-loop operation
• 3-wire configuration with blade terminals and male connector
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Metal housing and high-temperature-resistant construction for demanding exhaust conditions
• Wiring harness included with 34.1 in harness length and 36.6 in sealing-surface-to-connector length
• Cross-reference: This part cross-references 226910W003 for the same application.

Product Details

As part of Bosch’s Actual OE Oxygen Sensor line, part number 13228 reflects Bosch’s long OE development history in switching-type oxygen sensing. The sensor uses a narrow-band heated design to deliver accurate lambda feedback during warm-up and normal operation, helping the engine control module maintain the correct air-fuel balance. For drivers searching for a Bosch 13228 oxygen sensor for Nissan Pathfinder or INFINITI QX4 service, this unit matches the listed upstream positions and uses the specified threaded, 3-wire layout.

Compatible vehicle coverage includes 1996-2000 Nissan Pathfinder, Upstream Left; 1997-2000 INFINITI QX4, Upstream Left; 1995-1997 Nissan Maxima, Upstream Left and Upstream Right; and 1996-1998 INFINITI I30, Upstream Left and Upstream Right. If you need a Bosch 13228 replacement oxygen sensor for a Nissan Maxima or INFINITI I30, verify the exact upstream position before ordering.

What It Helps Address

• Check engine light caused by an aging upstream oxygen sensor
• Rough idle or unstable air-fuel control after sensor degradation
• Delayed closed-loop operation during cold start
• Inaccurate exhaust oxygen feedback affecting fuel trim control
• Emissions test failures related to sensor response or signal quality

Installation Notes

Confirm the vehicle year, make, model, and sensor position before installation. This Bosch oxygen sensor uses a threaded mount, 18 mm thread size, and a male oblong connector with 3 terminals. Inspect the harness routing and connector condition before installation, and compare the existing sensor length and connector location to the listed dimensions for proper fitment.

Quality Assurance

Bosch supplies this Actual OE Oxygen Sensor using OE-proven engineering, ceramic sensing elements, optimized heater control, and materials selected for high heat and vibration exposure. The design reflects Bosch’s long-standing OE development in oxygen sensing for consistent signal accuracy and durable service in the aftermarket.
