Exhaust Gas Temperature Sensor Connector

Standard Ignition S3157 is an exhaust gas temperature (EGT) sensor connector built for direct service on select Ram, Mercedes-Benz, Jeep, and Chevrolet applications. It features a female connector with an oval housing, 18-inch harness length, and 2 blade terminals for a clean electrical repair at the exhaust sensor connection.

Key Features

  • Female EGT sensor connector with oval housing
  • 18-inch harness length for routing flexibility
  • 2 blade terminals with 18-gauge wiring
  • Single connector design with 0-degree bend angle
  • Standard Ignition S3157 for exhaust electrical repair

Detailed Description

This Standard Ignition S3157 exhaust gas temperature sensor connector is used in exhaust system electrical repairs where the original connector is heat-aged, damaged, or no longer making a stable signal connection. The 45 cm harness and compact housing length help support service on vehicles with sensor locations near the exhaust manifold, catalytic converter, or before the particulate filter. Compatible vehicle coverage includes 2020-2023 Ram 2500, 2019-2023 Ram 3500, 2015-2019 Chevrolet Corvette, and multiple Mercedes-Benz diesel applications. This part cross-references 68528072AA and EC3182 for the same application.

What It Helps Fix

  • Broken or heat-damaged EGT sensor connector housing
  • Intermittent exhaust temperature sensor signal loss
  • Corrosion at the original blade terminal connection
  • Harness damage near hot exhaust components
  • Faults caused by poor contact at the sensor plug

Installation Notes and Tips

  • Verify connector shape, terminal style, and harness length before installation.
  • Match the vehicle’s sensor location, including exhaust manifold, catalytic converter, or before particulate filter applications.
  • Inspect nearby wiring for heat damage before connecting the replacement plug.
  • Confirm secure terminal engagement to maintain a stable electrical connection.

Quality Assurance

Standard Ignition is a recognized aftermarket source for electrical service parts, and S3157 is built to match the connector style and fitment details listed for the covered applications.
