Standard Ignition S2522 Exhaust Gas Temperature (EGT) Sensor Connector

Exhaust Gas Temperature Sensor Connector for OE Repair

Standard Ignition S2522 is a weatherproof sealed exhaust gas temperature (EGT) sensor connector built for clean electrical repair at the sensor harness. It uses a male connector body with an oval shape, 20-gauge wiring, and a 2-terminal blade design for a direct-fit style connection on supported applications.

Use this connector when servicing EGT-related wiring on vehicles such as the Chevrolet Colorado, GMC Canyon, and Silverado HD platforms, where the connector location may be between the intercooler and throttle body or on the EGR cooler/crossover tube depending on application.

Key Features

• Standard Ignition S2522 exhaust gas temperature sensor connector
• Male connector with oval housing for OE-style fitment
• Weatherproof sealed construction for protected electrical connection
• 2-terminal blade interface with female terminals
• 20-gauge, 2-wire harness with 8.2 cm (19 in.) harness length
• Fits supported GM diesel and gas applications, including Chevrolet Colorado and GMC Canyon

Detailed Description

The Standard Ignition S2522 is an exhaust gas temperature sensor connector used to restore a secure electrical connection in emissions and engine management circuits. Its sealed housing helps protect the connection point, while the 2-blade terminal layout and 20-gauge wire size support a factory-style repair on vehicles that use this connector style. This part cross-references ACDelco PT2507 and Dorman 645-906 for the same application.

Fitment coverage includes 2016-2020 Chevrolet Colorado and GMC Canyon between the intercooler and throttle body, 2017-2018 Chevrolet Silverado 2500 HD, Silverado 3500 HD, GMC Sierra 2500 HD, and Sierra 3500 HD between the intercooler and throttle body, plus additional coverage on Chevrolet Express, GMC Savana, and Silverado/Sierra HD applications where the connector is located on the EGR cooler or EGR crossover tube. The S2522 also appears in select Audi A6 and A7 applications listed in the fitment data.

What It Helps Fix

• Broken or heat-damaged EGT sensor connector housing
• Intermittent sensor signal caused by loose or corroded terminals
• Wiring repair needs at the EGR cooler or throttle body area
• Connector replacement after harness damage from engine heat and vibration
• Faults related to poor electrical contact at the exhaust gas temperature sensor circuit

Installation Notes and Tips

Match the connector shape, terminal style, and wire gauge to the original harness before installation. Confirm the sensor location on the vehicle, since fitment notes vary by application, including between intercooler and throttle body, on throttle body, on EGR cooler, and on EGR crossover tube. Verify pin orientation and terminal engagement before final assembly.

Quality Assurance

Standard Ignition S2522 is built as a sealed replacement connector for service repairs where a reliable electrical connection is required. Standard Ignition is a recognized aftermarket source for electrical components and connector service parts.
