Your vehicle’s coolant temperature sensor (CTS) monitors the engine’s heat levels and sends data to the computer to adjust fuel delivery, ignition timing, and cooling fan operation. In this video, Circle & Square Auto Care explains how our technicians test and replace faulty temperature sensors to keep your engine running efficiently and safely.
When the CTS fails or provides inaccurate readings, it can cause hard starts, poor fuel economy, erratic temperature gauge behavior, or overheating. Our ASE-certified technicians use precision diagnostic tools to compare live temperature data with actual coolant conditions, ensuring the readings are accurate and the system is operating correctly.
If a fault is found, we replace the sensor with a high-quality OEM part and check related systems — including wiring, thermostat function, and coolant flow — following the same thorough process outlined in our cooling system service.
At Circle & Square Auto Care, we take a preventive approach to cooling system maintenance — ensuring your vehicle stays within the proper temperature range for performance, efficiency, and long-term reliability.
