Drive Motor A Phase U-V-W Current Sensor Correlation
The phase U, V, and W current sensors of drive motor A do not correlate within the calibrated tolerance. Sum of phase currents should be near zero.
Affected components
- Drive motor a phase u current sensor
- Drive motor a phase v current sensor
- Drive motor a phase w current sensor
Common causes
- High likelihood: One sensor offset drifted
- Medium likelihood: Ground offset between sensors
Possible symptoms
- EV/hybrid system warning light on
- Reduced motor power or torque
- Possible limp mode or vehicle shutdown
Diagnostic notes
- The malfunction indicator lamp may illuminate
- Reduced-power or limp mode may occur
