P0115 Code: Engine Coolant Temperature Sensor 1 CircuitDiagnostic trouble code (DTC) P0115 stands for “Engine Coolant Temperature Sensor Circuit.” This code sets when the powertrain control module (PCM) detects erratic or irrational input signals coming from the engine coolant temperature (ECT) sensor circuit. The code may also register if the PCM detects an abnormally low or high P0119 Code: Engine Coolant Temperature Sensor 1 Circuit Intermittent/ErraticDiagnostic trouble code (DTC) P0119 stands for “Engine Coolant Temperature Sensor 1 Circuit Intermittent/Erratic.” This trouble code sets when the powertrain control module (PCM) perceives that the input signal from the engine coolant temperature (ECT) sensor is intermittent or erratic for a set period of time.
