Standard Ignition S3134 Oxygen Sensor Connector

Oxygen Sensor Connector for Hyundai, Kia, and Mitsubishi

Standard Ignition S3134 is an oxygen sensor connector built for direct replacement on a wide range of Hyundai, Kia, Mitsubishi, Chrysler, and Dodge applications. It uses a 4-blade terminal layout with a female connector housing and a 350 mm harness length for service on downstream and upstream sensor circuits where the original connector is damaged or worn.

• Female connector with rectangle housing
• 4 terminal blade design with 4-wire configuration
• 18-gauge harness with 350 mm / 14 in. lead length
• 0-degree bend angle for straight routing
• Fits many Hyundai Sonata, Kia Optima, and Mitsubishi Outlander applications
• Standard Ignition S3134 cross-references CONB10865 and EC3159 for the same application

Detailed Product Overview

Standard Ignition S3134 is an OE-style oxygen sensor connector for repairing damaged sensor wiring on select import vehicles. The female connector body, male blade terminals, and rectangular housing are specified for a secure electrical connection, while the 35 cm harness length provides room for routing during repair. This part number is used across many Hyundai Genesis, Hyundai Santa Fe, Kia Sorento, and Mitsubishi Eclipse applications, including downstream and upstream sensor locations listed in the fitment data.

Because oxygen sensor circuits are sensitive to connection quality, a correct connector replacement helps restore stable signal transfer between the sensor and the engine control system. Standard Ignition S3134 is a practical service part for vehicles with heat-damaged, corroded, or broken sensor connectors.

What This Part Helps Fix

• Broken or cracked oxygen sensor connector housings
• Corroded terminals causing intermittent sensor signals
• Heat-damaged wiring near the exhaust stream
• Loose or unreliable oxygen sensor electrical connections
• Check engine light concerns related to connector failure

Installation Notes and Tips

Verify connector shape, terminal count, and harness length before installation. Match the vehicle side and sensor location exactly, since fitment includes downstream and upstream positions on select models. Inspect the existing wiring for heat damage or corrosion before splicing or reconnecting the harness. Confirm proper terminal engagement and secure routing away from exhaust components after installation.

Quality Assurance

Standard Ignition supplies electrical service parts for repair applications, and S3134 is listed with direct interchange references for matching applications. Confirm fitment against the vehicle year, make, model, and sensor position before ordering.
