2017-10-10

Description:

  • The fault code P0515 indicates that there is an issue with the circuit that monitors the battery temperature sensor. This can affect the performance of the battery and charging system.

Possible Symptoms:

  • Illuminated check engine light

  • Reduced battery performance

  • Difficulty starting the engine

  • Poor charging system performance

Possible Causes:

  • Faulty battery temperature sensor

  • Corroded or damaged wiring or connections in the circuit

  • Failed engine control module (ECM)

  • Battery temperature sensor circuit shorted to ground

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 or corroded wiring or connections

  • Replace the engine control module (ECM) if necessary

  • Inspect the circuit for shorting to ground
