P1A4B: Understanding Your Car’s Battery Temperature Sensor Issue
The P1A4B code refers to the Hybrid Battery Current Sensor Performa. It is a current sensor based on the closed-loop principle.
It uses a soft-magnetic probe as a field detector of the primary current magnetic field. Compared to standard sensors with Hall-probes, it offers low offset currents, small temperature dependence, and no long term drift of offset current. It also has small offset current forces and a compact size.
Separate electronics are available for this code.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the P1A4B fault code.
