Standard Ignition ETS155 Exhaust Gas Temperature (EGT) Sensor - Front

Exhaust Gas Temperature Sensor for OE-Style Repair

The Standard Ignition ETS155 is a direct-fit exhaust gas temperature (EGT) sensor built for accurate temperature monitoring in emission control systems. It is engineered for the front position on select Chevrolet Express 2500, Chevrolet Express 3500, GMC Savana 2500, and GMC Savana 3500 applications.

With OE-match connectors and terminals, the ETS155 supports reliable signal transfer and a proper factory-style connection on the vehicle.

Key Features

• Direct-fit OE replacement for proper fit, form, and function
• Measures exhaust temperature with accuracy within approximately 10 degrees of actual temperature
• Built to handle extreme vibration and heat up to 2300 degrees F (1300 degrees C)
• Female oval plug-in connector with male blade terminals
• OE-match connector design for accurate readings and secure electrical contact
• Standard Ignition ETS155 for emission control sensor replacement

Detailed Description

The Standard Ignition ETS155 exhaust gas temperature sensor is designed for vehicles that rely on precise exhaust temperature feedback to manage emission control operation. Its direct-fit design helps maintain factory-style installation geometry, while the OE-matched connector and terminal layout support consistent electrical performance. This sensor is a practical replacement choice for 2010-2016 Chevrolet Express 2500 and Express 3500, as well as 2010-2016 GMC Savana 2500 and Savana 3500 models in the front position. This part cross-references Dorman - OE Solutions 904-708 for the same application.

What It Helps Address

• Faulty exhaust temperature readings from a worn or failed sensor
• Emission control warning lights related to EGT sensor performance
• Driveability issues caused by inaccurate exhaust temperature data
• Connector or terminal mismatch during sensor replacement
• Heat- and vibration-related sensor degradation in the exhaust stream

Installation Notes and Tips

Verify the connector shape, gender, and terminal style before installation. This sensor uses a female oval plug-in connector with two male blade terminals, so matching the harness connection is important for a secure fit. Confirm front-position placement and compare the original sensor location on the vehicle before replacement. For 2010-2016 Chevrolet Express 2500 and Chevrolet Express 3500 front applications, as well as 2010-2016 GMC Savana 2500 and GMC Savana 3500 front applications, use the vehicle’s original routing and mounting points as a reference.

Quality Assurance

Standard Ignition states that this sensor is manufactured under complete quality control throughout the production process. The ETS155 is built to meet OE-style fit and function requirements for dependable exhaust temperature monitoring.
