P0515 Battery Temperature Sensor Circuit

OBD2 Code: P0515

Description: Battery Temperature Sensor Circuit

Definition: The P0515 code indicates a malfunction in the battery temperature sensor circuit, which is responsible for monitoring the temperature of the vehicle’s battery to ensure optimal performance and prevent overheating.

p0515 – Battery Temperature Sensor Circuit

Typical Severity: Moderate

Common Causes

p0515 – Battery Temperature Sensor Circuit

Description: The powertrain control module (PCM) monitors the battery temperature sensor circuit for high voltage. If the voltage is above a certain threshold, the PCM will set code P0515.

Common Causes:

• Faulty battery temperature sensor
• Corroded or damaged wiring in the battery temperature sensor circuit
• Loose or poor connection at the battery temperature sensor
• Issues with the powertrain control module (PCM)

 

Common Misdiagnosis

OBD2 Code: P0515

Description: Battery Temperature Sensor Circuit

Common Misdiagnosis: Replacing the battery or alternator without checking the battery temperature sensor or its wiring.

 

Common Diagnostic Steps

OBD2 Code: P0515

Description: Battery Temperature Sensor Circuit

Common Diagnostic Steps:

• Verify the code with an OBD-II scanner. Clear the codes and perform a road test to see if the code returns.
• Inspect the battery temperature sensor for any signs of damage or corrosion.
• Check the wiring and connectors associated with the battery temperature sensor for any loose connections, frayed wires, or corrosion.
• Test the battery temperature sensor using a multimeter to ensure it is functioning within specifications.
• If necessary, replace the faulty battery temperature sensor with a new one.
• Recheck for any additional trouble codes that may have been triggered by this issue.
