Exhaust Gas Temperature Sensor for Ram Diesel Applications

Standard Ignition ETS178 is a direct-fit exhaust gas temperature (EGT) sensor built for accurate temperature monitoring in diesel exhaust systems. It is engineered for Ram 1500 and Ram 1500 Classic applications that place the sensor before the particulate filter, with OE-style fit, form, and function.

  • Direct-fit OE replacement for straightforward sensor replacement
  • Measures exhaust temperature with accuracy within +/-10 degrees of actual temperature
  • Female plug-in connector with OE-match terminal design
  • Built to handle extreme vibration and heat up to 2300 degrees F (1300 degrees C)
  • High-quality terminals support consistent signal transfer and readings
  • Standard Ignition ETS178 for diesel emission control service

Fitment and Application Details

Compatible with 2014-2018 Ram 1500, before the particulate filter, and 2019 Ram 1500 Classic, before the particulate filter. This EGT sensor is a direct replacement for Ram 1500 diesel exhaust temperature monitoring where precise pre-DPF measurement is required. If you are searching for a Ram 1500 EGT sensor or Standard Ignition ETS178 for a Ram 1500 Classic, this part matches the listed OE-style application.

This part cross-references Dorman OE Solutions 904-789 for the same application.

What This Sensor Helps Address

  • Faulty exhaust gas temperature readings
  • Diesel emission control warning lights related to sensor performance
  • Incorrect temperature data before the particulate filter
  • Sensor failure caused by heat and vibration exposure
  • Driveability issues tied to inaccurate exhaust monitoring

Installation Notes and Tips

Install ETS178 in the pre-particulate-filter location specified for the listed Ram applications. Verify the female plug-in connector and 2-blade terminal layout match the original sensor before installation. Confirm the sensor location and harness routing against the vehicle service information to ensure proper placement and signal integrity.

Quality Assurance

Standard Ignition manufactures this sensor with OE-match connectors and quality-controlled production processes. The design is intended to deliver proper fit, form, and function for emission control service on Ram diesel applications.
