Temperature sensor

VOLTREK temperature sensors measure coolant, oil, air and exhaust temperature for accurate engine control.

VOLTREK coolant temperature sensor

Temperature sensors give the control unit one of the most important values for engine management. Coolant temperature affects fuel metering and fan control; intake air and exhaust gas temperatures are used to protect the engine and the emissions systems.

VOLTREK produces its temperature sensors with a resistance curve calibrated to the specification of the original part, secure sealing against fluid and pressure, and thread and connector that allow direct fitment.

Frequently asked questions

What happens when the coolant temperature sensor fails?
The control unit receives a wrong value and may inject more fuel, run the fan at the wrong time or switch on the warning light.
