Q: What does code P2D7E mean?

Charging Start Switch Circuit. P2D7E indicates that the powertrain control module (PCM) has detected a fault in the charging start switch circuit, which is used to signal when the engine start sequence engages the charging system. The PCM monitors the circuit for expected voltage changes during cranking and running, and sets this code when the signal is missing, erratic, or out of range.
