Product Description
A GM coolant temperature sensor (ECT sensor) is an Engine Control Module (ECM) sensor that measures the engine's coolant temperature to provide real-time data to the onboard computer. This data is used to adjust the air/fuel mixture and ignition timing for optimal engine performance and to alert the driver to potential overheating. These sensors are GM-recommended replacements, designed to fit and perform like the original factory components for various GM vehicles. Replacement for 12608814 part number.
Function & Purpose
-
Temperature Monitoring:The primary role of the ECT sensor is to accurately measure the engine's coolant temperature.
-
Data for the ECM:The sensor sends this temperature data to the vehicle's ECM, which uses it for critical adjustments.
-
Performance Optimization:By knowing the coolant temperature, the ECM can precisely control the engine's air/fuel mixture and ignition timing, ensuring the engine runs efficiently and smoothly.
-
Overheating Alert:The sensor also helps to monitor for high engine temperatures and can trigger alerts to the driver, protecting the engine from damage.
