The automobile fault code P3056 has an estimated repair time of 1.0 hour. The cost of fixing this fault code is influenced by the repair time.

Most auto repair shops charge between $75 and $150 per hour for their services.

Therefore, the fixing cost of P3056 will range between $75 and $150, depending on the repair time required.

The P3056 fault code indicates a malfunction in the battery current sensor circuit. The sensor is responsible for detecting the amperage that flows into the HV battery.

It inputs a voltage into the battery ECU, which determines the charging and discharging amperage of the HV battery. The battery ECU also calculates the state of charge of the HV battery based on the amperage estimation. A voltage output below 2.5 V indicates charging, while above 2.5 V indicates discharging.

What are the possible causes of the automobile fault code P3056?

If you see the engine light on or the service engine soon warning light, it could be due to the P3056 fault code. This code is usually caused by a faulty HV battery assembly, an open or shorted HV battery assembly harness, poor electrical connection in the HV battery assembly circuit, a faulty battery current sensor, or a faulty battery ECU. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
