Q: What does code P2D8D mean?

Engine Disconnect Clutch Mechanical Performance. This code indicates that the powertrain control module (PCM) has detected a mechanical performance problem with the engine disconnect clutch, which is the clutch that couples and decouples the engine from the transmission in hybrid and certain automatic-stop-start vehicles. The PCM monitors signals such as engine speed, transmission input speed, and clutch actuator position to determine whether the clutch is engaging and disengaging as commanded, and it sets this code when the actual response does not match the expected response within a calibrated time window.
