P0A95 High Voltage Fuse

P0A95 indicates a high-voltage fuse fault. The hybrid controller sees voltage or continuity behavior suggesting a fuse or protected high-voltage path is open.

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not replace a high-voltage fuse without finding the overcurrent or short condition that may have opened it.

Useful checks before replacing parts

Review pack voltage, load-side voltage, contactor state, precharge voltage, freeze-frame data, and related converter, inverter, or no-ready codes.
Inspect service disconnect seating, high-voltage fuse condition according to service procedure, connector damage, water intrusion, and evidence of overcurrent events.
Use approved high-voltage testing procedures to determine whether the fuse opened or voltage sensing is misleading.
