Give Your Link ECU Accurate Engine Temperature Data

The Link ECU M12 Coolant Temperature Sensor provides your engine management system with the coolant temperature data it needs for proper startup, warm-up, fueling, ignition control, fan operation, and engine protection.

Designed for use with compatible Link ECUs, this sensor features an M12 threaded body and comes complete with the matching plug and terminals, making it an excellent solution for custom wiring harnesses, engine swaps, and standalone ECU installations.

Why Coolant Temperature Data Matters

Engine coolant temperature is one of the most important inputs your ECU monitors.

Your Link ECU can use coolant temperature information for functions such as:

• Cold-start enrichment
• Warm-up enrichment
• Idle control
• Cooling fan control
• Fuel corrections
• Ignition corrections
• Datalogging
• Over-temperature warnings
• Engine protection strategies

Accurate temperature information allows the ECU to respond appropriately whether the engine is being started cold, operating at normal temperature, or beginning to overheat.

M12 Threaded Sensor

The M12 threaded design makes this sensor suitable for many engine and coolant-system applications where an M12 temperature-sensor port is available.

It's an excellent option when building a custom engine-management system or replacing an incompatible factory sensor.

Plug & Terminals Included

No need to hunt down the correct connector separately.

This kit includes the components needed to integrate the sensor into your wiring harness:

• Link ECU coolant temperature sensor
• Matching electrical plug
• Connector terminals
• Protective connector boot

This makes it especially convenient when building a new harness from scratch.

Perfect for Standalone ECU & Engine Swap Applications

The Link M12 Coolant Temperature Sensor is a great choice for:

• Custom Link ECU installations
• Engine swaps
• Turbocharged builds
• Naturally aspirated performance engines
• K-Series swaps
