P1115 SUZUKI Meaning
The Engine Coolant Temperature (ECT) sensor is used to detect the engine coolant temperature. The sensor modifies a voltage signal from the Engine Control Module (ECM). The modified signal returns to the ECM as an engine coolant temperature input. The sensor uses a thermistor sensitive to temperature change. The electrical resistance of the thermistor decreases as temperature increases.
