Key Features

• Male connector with a rectangular housing for a secure electrical interface
• 4-wire, 4-terminal blade design for oxygen sensor circuit repair
• 18-gauge harness with 430 mm (17 in.) lead length
• 0-degree bend angle for straightforward routing
• Compatible with select Honda Civic, Honda Accord, CR-V, Pilot, and Acura models

Detailed Description

Standard Ignition S3086 is an oxygen sensor connector intended for repairing or replacing a damaged connector on the vehicle-side harness. The 4-terminal female blade interface, 18-gauge wire, and 43 cm harness length support a clean splice-in repair where the original connector has heat damage, corrosion, broken locking tabs, or terminal wear. This part number is used across a wide range of Honda and Acura fitments, including 2012-2021 Honda Civic, 2018-2020 Honda Accord, and multiple CR-V, Pilot, MDX, and RDX applications. If you are sourcing a replacement oxygen sensor connector for a Honda Civic or Acura MDX downstream sensor circuit, S3086 is a direct-reference option to verify against the original connector style.

Common Repair Uses

• Broken or melted oxygen sensor connector housing
• Corroded terminals causing intermittent sensor signal loss
• Damaged wiring near the exhaust or underbody harness
• Failed downstream sensor connector on Honda and Acura models
• Connector mismatch during oxygen sensor harness repair

Installation Notes

Confirm the original connector shape, terminal count, and wire gauge before installation. Match the vehicle application by year, make, model, and sensor position, since this part is listed for both upstream and downstream locations on certain vehicles. For best results, compare the existing connector to the S3086 harness length and terminal layout before splicing into the vehicle wiring.

Quality Assurance

Standard Ignition supplies electrical connectors for service replacement applications, and S3086 is cataloged with OE-style fitment references for select Honda and Acura vehicles. Verify the connector against the original part and vehicle service information before installation.
