NTK EF0102 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for OE Fitment

The NTK Engine Coolant Temperature Sensor, part number EF0102, is built for accurate coolant temperature monitoring in select Ram, Dodge Ram, and Nissan TITAN XD applications. It uses a blade terminal design with an oblong female connector to match the original sensor connection on covered vehicles.

NTK draws on OE sensor experience and extensive testing to deliver a replacement that meets or exceeds OE specifications. This EF0102 sensor is part of the NTK Engine Coolant Temperature Sensor line, created to give import and domestic vehicle coverage under one technical-sensor brand.

Key Features

• Engine coolant temperature sensor for monitored coolant temperature signal output
• Blade terminal type with 2 terminals
• Oblong female connector for OE-style electrical connection
• No wiring harness included
• Built and tested to OE-level standards, including thermal shock, vibration, and OBD verification
• Part number EF0102 for easy cross-reference

Detailed Description

NTK EF0102 is an engine coolant temperature sensor engineered for vehicles that rely on precise coolant temperature input for engine management and gauge operation. It is a direct-fit style replacement for select 1998-2022 Ram 2500, Ram 3500, Dodge Ram 2500, Dodge Ram 3500, and 2016-2019 Nissan TITAN XD applications. The sensor’s blade terminals, 2-terminal layout, and oblong female connector support OE-style electrical integration without modification to the vehicle harness.

NTK’s technical sensor program is backed by more than 80 years of automotive experience through NGK and NTK. The brand’s OE background and application coverage make EF0102 a practical choice when replacing a failing coolant temperature sensor on Ram 2500, Ram 3500, or Nissan TITAN XD platforms. This part cross-references Standard Ignition TX141 for the same application.

What It Helps Address

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting or rough running related to inaccurate temperature input
• Cooling fan control issues caused by a faulty temperature signal
• Check engine light conditions tied to coolant temperature sensor faults
• Driveability problems from inconsistent engine temperature data

Installation Notes and Tips

Verify connector shape, terminal count, and OE part number before installation. Inspect the mating connector and wiring for corrosion, heat damage, or loose terminals, since electrical issues can mimic sensor failure. Confirm the cooling system is at a safe temperature before removing the old sensor, and check for proper coolant level after service.

Compatible With 1998-2002 Dodge Ram 2500, 1998-2002 Dodge Ram 3500, 2004-2010 Dodge Ram 2500, 2004-2010 Dodge Ram 3500, 2011-2022 Ram 2500, 2011-2022 Ram 3500, and 2016-2019 Nissan TITAN XD.
