The coolant temperature sensor on a 1997 S-10 pickup monitors the temperature of the engine's coolant. It provides this information to the engine control unit (ECU), which uses the data to adjust fuel injection and ignition timing for optimal engine performance and efficiency. Additionally, the sensor helps regulate the engine's cooling fan operation and can trigger the check engine light if it detects an issue. Proper functioning of this sensor is essential for maintaining engine temperature and preventing overheating.
