Standard Ignition S3135 Oxygen Sensor Connector

Oxygen Sensor Connector for Nissan and INFINITI

Standard Ignition S3135 is an oxygen sensor connector built for downstream sensor service on select Nissan, INFINITI, and Suzuki applications. It is a direct-fit electrical connector with a 4-blade terminal layout, 18-gauge wiring, and a 38 cm harness length for repair work on damaged or corroded sensor leads.

Use S3135 when you need a replacement oxygen sensor connector for right-side downstream sensor circuits on vehicles such as the Nissan Frontier, Pathfinder, Xterra, and 350Z, as well as select INFINITI M45, FX45, and G35 applications.

• Brand: Standard Ignition
• Part number: S3135
• Oxygen sensor connector for downstream sensor wiring repair
• Male connector gender with female blade terminals
• 4-terminal, 4-wire design
• Oval and rectangle connector shapes
• 18-gauge harness with 380 mm (15 in.) length

Detailed Product Information

Standard Ignition S3135 is an electrical connector used to restore the connection between the vehicle harness and the oxygen sensor on confirmed applications. The 0-degree bend angle and 1 1/4-inch housing length support a clean routing path in tight underbody and exhaust-area locations. This part cross-references CONB10866 and EC3160 for the same application.

Compatible With: 2012-2014 Nissan NV1500, right downstream sensor; 2012-2014 Nissan NV2500, right downstream sensor; 2012-2014 Nissan NV3500, right downstream sensor; 2005-2012 Nissan Frontier, right downstream sensor; 2005-2012 Nissan Pathfinder, right downstream sensor; 2005-2012 Nissan Xterra, right downstream sensor; 2009-2012 Suzuki Equator, right downstream sensor; 2006-2010 INFINITI M45, right downstream sensor; 2003-2008 INFINITI FX45, right downstream sensor; and additional listed Nissan and INFINITI downstream sensor applications.

Common Repair Uses

• Broken oxygen sensor connector housing
• Heat-damaged or brittle sensor wiring near the exhaust
• Corroded terminals causing intermittent sensor signal loss
• Repair of a damaged downstream sensor pigtail on Nissan and INFINITI models
• Restoration of a right-side oxygen sensor connection after wiring failure

Installation Notes and Tips

Verify connector shape, terminal count, and wire routing before installation. Match the vehicle-side connector to the listed male/female terminal orientation and confirm the application is for the downstream sensor position noted in the fitment data. Inspect nearby exhaust components and wiring insulation for heat damage before completing the repair.

Quality Assurance

Standard Ignition is a recognized aftermarket electrical parts brand, and S3135 is built to match the connector style and harness configuration used on the listed Nissan, INFINITI, and Suzuki applications.
