Standard Ignition ETS177 Exhaust Gas Temperature (EGT) Sensor

Exhaust Gas Temperature Sensor for Ram ProMaster

The Standard Ignition ETS177 is a direct-fit exhaust gas temperature (EGT) sensor for select Ram ProMaster vans. It is built to match OE fit, form, and function, with accurate temperature detection and OE-style electrical connections for reliable signal transfer.

Designed for the exhaust stream, this sensor is made to handle severe heat and vibration while maintaining precise readings in demanding diesel emission control systems.

Key Features

• Direct-fit OE replacement for straightforward installation in the original sensor location
• Measures exhaust temperature with accuracy within approximately +/-10 degrees of actual temperature
• Built to withstand extreme vibration and heat up to 2300 degrees F (1300 degrees C)
• Female plug-in connector with oval shape for OE-style connection
• Male blade terminals with OE-match terminals for consistent electrical contact
• Standard Ignition ETS177 for emission control and exhaust temperature monitoring

Detailed Description

The Standard Ignition ETS177 exhaust gas temperature sensor is engineered for Ram ProMaster 1500, Ram ProMaster 2500, and Ram ProMaster 3500 models from 2014 to 2016. It is located in the catalytic converter at the front position and is designed to restore accurate exhaust temperature feedback for the vehicle’s emission control system. If you are replacing a failing Ram ProMaster EGT sensor, ETS177 provides an OE-style solution with the correct connector shape, terminal layout, and sensor response characteristics.

This part cross-references Walker Products 273-10365 for the same application.

What It Helps Address

• Check engine lights related to exhaust gas temperature sensor faults
• Incorrect exhaust temperature readings in the emission control system
• Diesel aftertreatment performance issues caused by a failing sensor
• Connector or terminal mismatch during replacement of the original sensor
• Heat-related sensor degradation in the catalytic converter area

Installation Notes and Tips

Verify the original sensor location before installation, since this application is listed as front and located in the catalytic converter. Compare the connector shape, gender, and terminal style to the removed part before connecting the harness. For Ram ProMaster 1500, Ram ProMaster 2500, and Ram ProMaster 3500 applications, confirm the part number ETS177 against the vehicle’s original sensor and service information.

Quality Assurance

Standard Ignition states that this sensor is manufactured under complete quality control throughout the production process. The ETS177 is built as an OE replacement to support proper fit, form, function, and accurate exhaust temperature measurement in demanding operating conditions.
