★ Top Answer
In a Chevy Malibu, if you see code p3056, it means there's a problem with the battery current sensor circuit. This sensor is attached to the negative cable side of the HV battery assembly and is responsible for monitoring the amperage going into the battery. The sensor sends a voltage signal to the battery ECU (which ranges from 0 to 5 V depending on the amperage) through the IB terminal. If the sensor's output voltage is below 2.5 V, it shows the battery is being charged, and if it's above 2.5 V, it indicates that the battery is being discharged.
