What does code P0A4E mean?

Q: What does code P0A4E mean?

Generator Position Sensor Circuit High. P0A4E means the generator position sensor circuit is reporting a voltage higher than the manufacturer's expected range to the hybrid or engine control module. The computer detects this when the sensor signal wire stays above the normal high threshold, indicating an open circuit, a short to voltage, or an internal sensor fault.
