P0515 Code - Battery Temperature Sensor Circuit

What Does P0515 Mean?

OBD-II Code Powertrain Control Module (PCM) failure is defined as a Battery Temperature Sensor Circuit

The Battery Temperature Sensor tells the engine control module (PCM) the temperature of the battery to prevent the battery from overheating. When the PCM detects an incorrect signal from this sensor, it will set code P0515.

What are the common causes of P0515 ?

• The Mass Airflow sensor is a hot wire that senses the volume of air entering the intake manifold. The computer uses this information to control fuel mixture.
• Defective ECU strategies or components will prevent proper regeneration
• Rarely - faulty Powertrain Control Module (PCM-programming required after replacement)

How do you troubleshoot P0515 ?

Like the all engines, the car engine system employs specially developed hydraulic lifters (known as switching roller followers) for the P0515 code intake and exhaust valves. The lifters can be collapsed by disengaging an internal locking pin. The locking pin is disengaged using solenoids to alter oil pressure fed into the lifter.
