Q: What does code P2D91 mean?

Engine Oil Pressure Sensor/Switch C Range/Performance. P2D91 indicates that the powertrain control module (PCM) has detected an out-of-range or erratic signal from the engine oil pressure sensor or switch circuit designated as 'C'. The computer compares the reported oil pressure against expected values for the current engine speed and temperature, and it flags this code when the signal falls outside the valid performance window or behaves implausibly.
