P1A4A: Understanding Your Car’s Battery Management System
The P1A4A code relates to the Hybrid Battery Current Sensor Performa. It is based on the closed-loop principle.
A soft-magnetic probe is used as a field detector of the primary current magnetic field. Compared to standard sensors with Hall-probes, the magnetic probe offers several application advantages.
These include low offset currents, small temperature dependence, and no long term drift of offset current. The sensor is also compact in size, and separate electronics are available.
