Starter/Generator Phase X-Y-Z Current Sensor Correlation
The phase X, Y, and Z current sensors of the starter/generator do not correlate within the calibrated tolerance. Sum of phase currents should be near zero.
Affected components
- Starter generator phase x current sensor
- Starter generator phase y current sensor
- Starter generator phase z current sensor
Common causes
- High likelihood: One sensor offset drifted
- Medium likelihood: Ground offset between sensors
Diagnostic notes
- The malfunction indicator lamp may illuminate
- Reduced-power or limp mode may occur
