What are the common causes of P0B57?

A short to power in the voltage sense F circuit. An open in the voltage sense F reference. A failed battery pack voltage sense F sensor reading high. An imbalanced battery pack.

Read battery pack voltage sense F on a scan tool. Check the sense F circuit for a short to power or an open. Compare the sense F reading to actual pack voltage. Test the battery pack cells for imbalance. Replace the sense F sensor if the reading stays high. Clear the code and retest.
