Function

The MD091056 is specifically the water temperature gauge sensor, meaning it is responsible for providing the coolant-temperature signal used by the vehicle’s factory temperature display. It is different from the separate engine coolant-temperature sensor used by the ECU for engine-management calculations.

A faulty gauge sensor can cause inaccurate, erratic, or missing temperature-gauge readings. Replacing it with the correct OEM sensor helps restore accurate factory coolant-temperature monitoring.

OEM Replacement

The MD091056 is an excellent replacement when servicing the cooling system, replacing a faulty temperature gauge sender, rebuilding a 4G63 engine, or restoring an Evo/DSM to OEM specification. It is catalogued as a genuine Mitsubishi component across the Evo 4–9 range and compatible 2G DSM/3000GT applications.
