Global Parts 1712643 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Engine Management

Global Parts 1712643 is an engine coolant temperature sensor used to send coolant temperature feedback to the engine management system. On modern vehicles, that signal helps the ECM manage A/C operation; on earlier vehicles, it can directly cycle the compressor off to help prevent compressor damage. This makes it a practical replacement for temperature-signal faults on applications such as Honda Civic and Toyota Corolla service needs.

Key Features

• Engine coolant temperature sensor for electronic temperature feedback
• Supports ECM-controlled A/C operation on modern systems
• Used in earlier systems to help shut the compressor off when needed
• Global Parts part number 1712643
• Cross-references Standard Ignition TX161 for the same application

Detailed Description

Global Parts 1712643 is built for vehicles that rely on coolant temperature input to manage engine and A/C operation. When the sensor signal is inaccurate or lost, the ECM may receive incorrect temperature data, which can affect compressor control and overall system behavior. This part cross-references Four Seasons 37897 for the same application. For buyers searching for an engine coolant temperature sensor for Honda Civic or Toyota Corolla service, 1712643 provides a direct replacement option for the original temperature-switch function.

Common Issues This Part May Address

• Incorrect coolant temperature signal to the ECM
• A/C compressor cycling problems tied to temperature input
• Compressor shutoff behavior that no longer matches engine temperature
• Faulty sensor-related drivability or HVAC control concerns

Installation Notes and Tips

Verify the connector style, thread size, and sensor location against the original part before installation. Clear any stored diagnostic trouble codes after replacement and confirm that coolant level and system operation are correct. For fitment-based searches, confirm the vehicle application by year, make, and model before ordering Global Parts 1712643.

Quality Assurance

Global Parts 1712643 is a replacement engine coolant temperature sensor designed to restore the temperature feedback function used by the ECM and A/C control strategy. It is listed with interchange references including Standard Ignition TX161 and Four Seasons 37897.
