Standard Ignition ETS166 Exhaust Gas Temperature (EGT) Sensor

Exhaust Gas Temperature Sensor for OE-Style Fit

The Standard Ignition ETS166 is a direct-fit exhaust gas temperature (EGT) sensor built for accurate temperature monitoring in diesel emission systems. It is engineered to match OE fit, form, and function for select Jeep Grand Cherokee and Ram 1500 applications, including upstream locations where specified.

• 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 handle extreme vibration and heat up to 2300 degrees F (1300 degrees C)
• Female oval plug-in connector with 2 male blade terminals
• OE-match connector design and quality terminals for consistent signal transfer
• Standard Ignition ETS166 for emission control sensor replacement

Detailed Product Overview

This exhaust gas temperature sensor is designed for vehicles that rely on precise exhaust monitoring to manage emission system performance. The ETS166 uses an OE-style connector layout and terminal design to support accurate readings, while its high-temperature construction helps it withstand the demanding environment near the exhaust stream. For buyers searching for a Jeep Grand Cherokee EGT sensor or a Ram 1500 exhaust gas temperature sensor, this part number provides a direct replacement option with application-specific fitment.

Standard Ignition ETS166 is a practical choice when replacing a worn or failed sensor on 2014-2017 Jeep Grand Cherokee upstream applications and 2015-2017 Ram 1500 upstream applications, as well as 2018-2021 Jeep Grand Cherokee and 2014, 2018 Ram 1500 listings shown below.

This part cross-references Delphi TS30236 and Dorman - OE Solutions 904-746 for the same application.

Vehicle Fitment

• Fits 2018-2021 Jeep Grand Cherokee, N/A
• Fits 2018 Ram 1500, N/A
• Fits 2014 Ram 1500, N/A
• Fits 2014-2017 Jeep Grand Cherokee, Upstream
• Fits 2015-2017 Ram 1500, Upstream

Common Issues This Sensor Can Address

• Faulty exhaust temperature readings from a failed EGT sensor
• Emission system warning lights related to sensor signal loss
• Incorrect temperature data affecting exhaust aftertreatment monitoring
• Connector or terminal wear causing intermittent sensor communication
• Heat-related sensor degradation in high-temperature exhaust environments

Installation Notes and Tips

Verify the connector style, terminal count, and application position before installation. The ETS166 uses a female oval plug-in connector with two male blade terminals, so matching the OE connector is important for proper fitment. Confirm whether your vehicle requires the upstream sensor location before ordering, especially on Jeep Grand Cherokee and Ram 1500 applications.

Quality Assurance

Standard Ignition manufactures this sensor with complete process control from production through final inspection. The ETS166 is built to OE-matching standards for fit, form, and function, with materials selected to handle vibration and sustained exhaust heat.
