Key Features

• Direct-fit engine coolant temperature sensor for straightforward installation
• Female connector with 1 plug-in connection
• 2 male pin terminals for secure electrical contact
• Built from quality materials for durability in cooling system service
• Tested for performance and reliability during manufacturing
• Standard TX155T cross-reference replacement for select OE-style applications

Detailed Description

The Standard TX155T is an engine coolant temperature sensor engineered for vehicles that rely on precise coolant temperature input for engine control, fuel strategy, and temperature monitoring. This part number is used across many Mercedes-Benz platforms, including C300, E350, GLC300, GLE350, GLS450, and Sprinter 2500, as well as select INFINITI Q50, Q60, QX30, and M37 applications. The TX155T also cross-references Standard Ignition TX155 and other listed aftermarket part numbers for the same application.

As a direct-fit replacement, the TX155T is built to match the original connection style and mounting expectations of the vehicle application. The connector design and terminal layout help support a clean electrical connection in the cooling system circuit.

What It Helps Address

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting or rough running related to temperature input errors
• Cooling fan operation concerns tied to sensor signal issues
• Check engine lights triggered by coolant temperature sensor faults
• Driveability problems caused by inaccurate engine temperature data

Installation Notes and Tips

Verify connector style, terminal layout, and vehicle application before installation. This sensor uses a female plug-in connector with 2 male pin terminals, so matching the electrical interface is important for proper fitment. On many Mercedes-Benz and INFINITI models, the sensor location varies by engine and platform; confirm the service location against the vehicle’s repair information before replacement.
