Standard Ignition S3133 is a replacement oxygen sensor connector for downstream sensor applications across a wide range of Hyundai, Kia, and select Mitsubishi and Dodge vehicles. It uses a 4-wire, male rectangular connector layout with a 14.5-inch harness length for direct repair of damaged or corroded sensor wiring.

Key Features

• Standard Ignition S3133 oxygen sensor connector
• Male rectangular connector with female blade terminals
• 4-wire, 4-terminal design for downstream sensor circuits
• 18-gauge harness with 14.5-inch (36 cm) lead length
• 0-degree bend angle for straightforward routing
• Fits many Hyundai Elantra, Kia Forte, Kia Soul, and Hyundai Sonata downstream sensor applications

Detailed Description

Built for oxygen sensor wiring repair, the S3133 connector is used on downstream sensor locations in many import applications. The rectangular housing, 4 blade-style female terminals, and 18-gauge wire layout support a clean replacement when the original connector is heat damaged, brittle, or no longer locking securely. This part cross-references EC3158 and PT3906 for the same application. Common fitment includes 2017-2020 Hyundai Elantra, 2020-2023 Kia Forte, 2010-2022 Kia Soul, 2015-2019 Hyundai Sonata, and 2016-2020 Kia Optima, along with additional Hyundai Elantra, Kia Rio, Kia Sportage, and Mitsubishi applications listed below.

What It Helps Fix

• Broken or melted oxygen sensor connector housings
• Corroded terminals causing intermittent sensor signals
• Damaged downstream sensor wiring near the exhaust
• Loose connector retention from worn terminal contacts
• Check engine light concerns related to oxygen sensor circuit faults

Installation Notes and Tips

Verify connector shape, terminal style, wire count, and harness length before installation. This connector is listed for downstream sensor use on most applications shown, including Fits 2017-2020 Hyundai Elantra, N/A; Fits 2020-2023 Kia Forte, N/A; and Fits 2010-2022 Kia Soul, N/A.
