What does code P2D8E mean?

Q: What does code P2D8E mean?

Engine Oil Pressure Sensor/Switch C Circuit. P2D8E indicates that the powertrain control module has detected a fault in the electrical circuit for engine oil pressure sensor or switch C, which is typically the third pressure sensor in systems with multiple monitoring points. The computer monitors the signal voltage from this sensor and sets the code when the voltage falls outside the expected range for the current engine operating conditions, indicating an open, short, or irrational signal.
