Generator Phase W Current Sensor Circuit Range/Performance
The generator phase W current sensor reports a circuit range/performance fault. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
Affected components
- Generator phase w current sensor
- Wiring harness
- Hybrid control module
Common causes
- High likelihood: Sensor offset drifted
- Medium likelihood: Magnetic offset
- Low likelihood: Sensor element aged beyond calibration window
Diagnostic notes
- The malfunction indicator lamp may illuminate
- Reduced-power or limp mode may occur
