Coolant Temperature Sensor - Ci Ignition - XTS25

It measures the engine's coolant temperature and sends this information to the vehicle's computer or dashboard warning light system to alert the driver of potential overheating.

Symptoms can include the coolant warning light staying on, the temperature gauge reading erratically, poor engine performance, or the engine running too cool or too hot. A diagnostic scan may also reveal sensor faults.

The thread size is M10 x 1.

No, it has a specific thread size (M10 x 1) and connector type. Compatibility must be verified against your vehicle's specifications and the listed cross-references.

This indicates a simple electrical connection, typically used for sensors that only need to signal one state, such as activating a warning lamp when a temperature threshold is reached.

A 19mm spanner is typically required to remove and install the sensor.

This specific sensor (XTS25) is designed primarily to activate a warning lamp. For temperature gauge readings, a different type of sensor, often with multiple poles or different electrical characteristics, may be required.

Check the electrical connection for security and corrosion. Ensure the sensor is fully screwed in and making proper contact. Verify the sensor is the correct part for your vehicle.

Verify the electrical connection. Test the sensor's function if possible, or consider replacing it with a new unit. Ensure the vehicle's dashboard warning light system is functional.

The sensor may not be tightened sufficiently or the threads may be damaged. Remove the sensor, inspect threads, and reinstall, ensuring a snug fit. Replace the sensor if threads are damaged.
