Global Parts 1712621 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Lexus and Toyota

Global Parts 1712621 is an engine coolant temperature sensor for select Lexus and Toyota applications with an M12 x 1.5 thread and 2 terminals. It sends coolant temperature feedback to the engine management system so the ECM can manage cooling-related functions accurately.

Key Features

• Engine coolant temperature sensor for electronic temperature feedback
• M12 x 1.5 thread with 2-terminal design
• Direct-fit application coverage for select Lexus GS, LS, IS, SC, GX, LX, and Toyota Land Cruiser, Sequoia, Tundra, and 4Runner models
• Global Parts part number 1712621
• Cross-references Standard Ignition TX40 for the same application

Detailed Description

This Global Parts engine coolant temperature sensor is used in the engine management system to report coolant temperature data. On modern vehicles, that information helps the ECM control A/C operation and related protection strategies; on earlier vehicles, it can directly switch the compressor off to help prevent compressor damage. Part number 1712621 is listed for select Lexus GS300, GS400, GS430, LS400, LS430, IS300, SC430, GX470, LX470 and Toyota Land Cruiser, Sequoia, Tundra, and 4Runner applications with the correct thread and terminal configuration.

This part cross-references Standard Ignition TX40 for the same application.

What It Helps Address

• Incorrect coolant temperature signal to the ECM
• A/C compressor shutdown caused by temperature input faults
• Cooling system warning behavior tied to sensor failure
• Hard starting or drivability issues related to inaccurate engine temperature data
• Fault codes associated with coolant temperature sensor circuits

Installation Notes and Tips

Verify the vehicle uses an M12 x 1.5 thread and 2 terminals before ordering. Confirm the connector style and sensor location against the original part, and inspect the cooling system for leaks or contamination during replacement. Global Parts 1712621 is listed for 1998-2010 Lexus and Toyota models, including 2001-2007 Lexus GS430, 2001-2006 Lexus LS430, and 2001-2005 Toyota Land Cruiser.
