BMW DTC P017D – Cylinder Head Temperature Sensor Circuit High
DTC P017D meaning on BMW
DTC P017D indicates that there is a high voltage condition detected in the cylinder head temperature sensor circuit of a BMW vehicle. The Engine Control Module (ECM) monitors the voltage signal from the cylinder head temperature sensor to determine the temperature of the cylinder head. A high voltage reading suggests that the sensor is reporting a temperature that is higher than expected.
