OBD-II Trouble Code Description for P0516 Skoda

Battery Temperature Sensor Circuit Low

What does this mean?

OBD2 Code P0516 Skoda definition:
The battery temperature sensor installed on the battery current sensor detects battery temperature. A thermistor is integrated into the battery temperature sensor, and the resistance in the battery temperature sensor changes according to the battery temperature. The resistance of the thermistor in the battery temperature sensor decreases as the battery temperature increases. The resistance increases as the temperature decreases. The battery temperature sensor is connected to the ECM. The ECM supplies 5 V from the THB terminal to the battery temperature sensor through resistor R. The battery temperature sensor and resistor R are connected in series. This results in fluctuations in the voltage supplied from the THB terminal when the resistance changes according to the battery temperature. The ECM determines the battery temperature according to fluctuations in voltage. When the battery temperature is high, the ECM determines to reduce the amount of current supplied from the generator in order to protect the battery.

Symptoms

Possible sumptoms of OBD code P0516 Skoda
– Engine Light ON (or Service Engine Soon Warning Light) – Possible engine overheating

Causes

Possible causes of OBD code P0516 Skoda
– Faulty battery temperature sensor – Short in battery temperature sensor circuit – Faulty ECM The Error code is generally activated on detection of the following conditions: Battery temperature sensor output value is 0.2 V or less for 0.5 seconds or more with the ignition switch ON
