What Does P0A61 Mean?
Drive Motor A Phase V current is reading below the expected minimum threshold. The hybrid control module detects that Phase V stator current in the primary drive motor is abnormally low during commanded operation, indicating a potential open winding, disconnected phase cable, or current sensor fault on the Phase V leg.
Safety Warning
Single-phase loss causes severe torque ripple and motor overheating. Do not drive — tow to a hybrid-certified repair facility.
Common Causes
35%
Open circuit in Phase V stator winding of drive motor A
25%
Phase V current sensor failure reading low within the inverter
25%
Disconnected or high-resistance Phase V power cable connection
15%
Inverter Phase V IGBT not switching (stuck open)
Diagnostic Steps
1
Step 1: Compare Phase V current with Phase U and W in live data — if V reads near zero while U and W show normal values, confirm a Phase V-specific fault.
2
Step 2: With HV system de-energized and safety locks engaged, measure continuity of Phase V winding from the motor terminal to the neutral point. An open reading confirms a broken winding.
3
Step 3: Inspect the Phase V high-voltage cable and both terminal ends for loose bolts, corrosion, or heat damage. Torque connections to OEM specification.
4
Step 4: If winding and cable are intact, test the inverter Phase V IGBT — measure gate-to-emitter and collector-to-emitter for opens. A failed-open IGBT prevents current flow on that phase.
5
Step 5: Replace the faulty component and verify balanced three-phase operation during a controlled motor function test before returning to service.
