What does code P2E8E mean?

Q: What does code P2E8E mean?

Battery Charger B Charge Sequence Signal 2 Circuit High. P2E8E indicates that the powertrain control module (PCM) has detected an abnormally high voltage on the charge sequence signal 2 circuit for battery charger B, which is typically part of a high-voltage battery charging system on hybrid or electric vehicles. The PCM monitors this dedicated signal line to confirm that the charger is following the commanded charge sequence, and a high voltage reading means the circuit is above the expected range, often due to a short to voltage or an open return path.
