P1DAA Acura Code - Voltage Control Unit V2S Voltage Sensor Range/Performance
Quick Answer
The motor control module judges the characteristics abnormality of V2S voltage sensor by comparing the voltage control state and V1 voltage reading, V2M voltage reading, and V2S voltage reading. Common causes include Faulty Voltage Control Unit (VCU), Voltage Control Unit (VCU) harness is open or shorted, Voltage Control Unit (VCU) circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
