VEMO Engine Coolant Temperature Sender Unit

The VEMO Engine Coolant Temperature Sender Unit (also called a coolant temperature sensor or coolant temp sensor) monitors the temperature of the engine coolant. It sends that data to the engine control unit (ECU) or the instrument cluster. The ECU uses the signal to manage fuel injection, ignition timing, cooling fan operation, and idle control. This helps the engine run efficiently, start reliably, and avoid overheating.

Key Features:

• Measures coolant temperature and sends an electrical signal to the engine management system or temperature gauge
• Supports accurate fuel mixture, ignition, and cooling fan control
• Made to meet or exceed OE-level requirements for fit and function
• Designed for consistent readings and durability in the heat and vibration of the engine bay
• Quality-tested by VEMO, a Germany-based brand of automotive replacement parts

A failing coolant temperature sensor can cause hard starting, poor fuel economy, rough idle, a false temperature reading, or a check engine light. Replacing a worn sender with a VEMO unit helps restore correct engine management and reliable temperature monitoring.
