Engine Coolant Temperature Gauge

The engine coolant temperature gauge sensor has the capability to sense from -40°C to +130°C. Petrol and Diesel resistance valves are different.

Both Petrol and Diesel sensors are interfaced to the Instrument Cluster (Z142) via the BeCM (Z238). The resistance value then being represented by an A/D data transfer generating the required angular deflection on this gauge. [A/D = Analog to Digital]
