DTCP0117
Circuit / System Description
The engine coolant temperature (ECT) sensor is a variable resistor, that measures the temperature of the engine coolant. The engine control module (ECM) supplies 5?volts to the ECT signal circuit and a ground for the ECT low reference circuit. When the ECT is cold, the sensor resistance is high. When the ECT increases, the sensor resistance decreases. With high sensor resistance, the ECM detects a high voltage on the ECT signal circuit. With lower sensor resistance, the ECM detects a lower voltage on the ECT signal circuit. If the ECM detects an excessively low ECT signal voltage, which is a high temperature indication, DTC?P0117 sets.
