Generator Position Sensor Circuit B Circuit Intermittent/Erratic
The generator position sensor channel B reports a circuit intermittent/erratic 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 position sensor b
- Wiring harness
- Hybrid control module
Common causes
- High likelihood: Connector not seated
- Medium likelihood: Noisy ground reference
- Low likelihood: Connector with intermittent contact under vibration
Diagnostic notes
- The malfunction indicator lamp may illuminate
- Reduced-power or limp mode may occur
