Description:

  • The fault code P0516 indicates that the battery temperature sensor circuit has a low voltage reading. This may cause the vehicle to have starting problems or poor performance.

Possible Symptoms:

  • Hard starting or no start

  • Illuminated check engine light

  • Reduced engine power or acceleration

Possible Causes:

  • Failed battery temperature sensor

  • Faulty wiring or connections in the circuit

  • Loose or corroded electrical connections

  • Failed engine control module (ECM)

Related Parts:

  • Battery Temperature Sensor: Batteries are temperature-sensitive and a battery's optimal operating temperature range is 40 to 70 degrees Fahrenheit. Battery temperature sensor monitors battery temperature during charging. If it senses a temperature variation, it orders the computer control system to change the charging rate. Problems make it hard to start car and may cause stalling

Possible Solutions:

  • Replace the battery temperature sensor

  • Check and repair any damaged wiring or connections

  • Tighten or clean any loose or corroded electrical connections

  • Replace the engine control module (ECM) if necessary
