Engine Coolant Temperature Sensor Overview

Global Parts 1814577 is an engine coolant temperature sensor built to report coolant temperature data to the ECM with the accuracy needed for proper engine management. When the coolant temp sensor begins to fail, cooling system control can be affected and overheating concerns can follow. This direct replacement sensor is made to OE specifications for service on vehicles such as Honda Civic and Toyota Corolla applications where precise temperature input matters.

Key Features

• Engine coolant temperature sensor for ECM temperature input
• Direct replacement design for OE-style service
• Built to meet OE specifications
• Blade terminal type with 2 terminals
• Female connector with oblong connector shape and 1 connector
• Global Parts part number 1814577

Detailed Product Description

Global Parts 1814577 is designed for accurate coolant temperature reporting so the engine control module can manage fuel strategy, cooling fan operation, and temperature-related engine functions. The sensor uses a blade terminal layout, a female connector, an oblong connector shape, and a 2-terminal configuration for a direct replacement fit where this style is specified. This part cross-references ES113129 for the same application. For buyers searching engine coolant temperature sensor replacement for Honda Civic or Toyota Corolla, 1814577 provides an OE-spec service option.

Common Issues This Sensor Can Help Address

• Incorrect coolant temperature readings at the ECM
• Cooling fan operation that does not follow engine temperature
• Overheating warnings tied to faulty temperature input
• Hard starting or drivability concerns related to temperature signal errors
• Check engine light conditions caused by a failing coolant temp sensor

Installation Notes and Tips

Confirm connector shape, terminal count, and terminal gender before installation to match the original sensor. Inspect the harness connector for corrosion, bent terminals, or heat damage before connecting the new unit. Drain coolant only as needed for access, and verify the cooling system is properly refilled and bled after service. For fitment-based searches, this engine coolant temperature sensor is a direct replacement option for Honda Civic and Toyota Corolla applications where the OE-style blade terminal, female connector design is required.
