What Does It Mean?
How to Fix Code P0A6F
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, ejected, or corroded connector pins.
P0A6F Possible Symptoms
Illuminated engine light (or service engine soon warning light)
P0A6F Meaning
The inverter converts high voltage DC current from the HV battery and AC current from MG1/MG2. The inverter contains a three-phase bridge circuit, which consists of 6 power transistors each for MG1 and MG2, to convert DC current and three-phase AC current.
The HV control ECU controls the operation of the power transistors.
The inverter transmits necessary information to perform control, such as current and voltage, to the HV control ECU.
The motor inverter current sensors detect the current flowing through the V and W phase cables between the inverter and MG1/MG2. The inverter transmits necessary information to perform control, such as current and voltage, to the HV control ECU.
The HV control ECU monitors the inverter current sensors to detect a malfunction in the sensor system.
