P1492 CHRYSLER, DODGE, JEEP, MITSUBISHI: BATTERY TEMPERATURE SENSOR VOLTAGE TOO HIGH
The Battery Temperature Sensor (BTS) is a feature of modern vehicle charging systems. In these electrical systems, the battery is an essential component for the good performance of the vehicle.
The Battery Temperature Sensor detects the temperature of the battery, thus checking that the charging system voltage is correct. If inconsistent values are found, the voltage is regulated according to the conditions. If the battery temperature is low, the system voltage is set high, and it will automatically decrease as the temperature rises.
The diagnostic code P1492 OBDII is set on Chrysler, Dodge, Jeep, and Mitsubishi vehicles because the PCM (Powertrain Control Module) has detected the Battery Temperature Sensor value has been above 4.9 volts for 3 seconds with the key on or the engine running.
The P1492 OBD2 fault code is set for one of the following reasons:
