What causes P1446 on a Honda?

One or more weak battery modules sagging under load Corroded module interconnect bus bars Voltage sense harness with an open or high resistance Aged pack with growing cell-to-cell imbalance Motor control module calibration drift

How do I fix P1446 on a Honda?

Log individual module voltages under assist load with an HDS scan tool Inspect interconnects and sense harness for corrosion and looseness Rule out sense-circuit faults before condemning the pack Balance or condition the pack if deviation is marginal Replace the battery pack if any module deviates beyond spec
