P0DA2 is stored when the lock position feedback flickers or drops out briefly, while it never sits at one limit long enough for the low or high verdict. No manufacturer documents this code publicly. The sibling procedures from Mitsubishi for the 2023 Outlander PHEV show where to look: the sensor lives in the lock actuator of the inlet harness, gets its supply and ground through a connector at the inlet, and Mitsubishi explicitly allows for intermittent faults when a code does not return after clearing. GM patent US8936482B2 explains why the reading matters: the module judges the lock state from how far the pin has travelled, so a jumping signal can make a latched plug look unlocked. CARB demands circuit checks on such inputs. Expect fast charging that aborts at random. Steady faults are P0D9E to P0DA1.

Likely causes

Loose or corroded contact at the lock actuator connector
Inlet harness chafed where it moves with the charge port flap or body
Worn lock mechanism letting the pin rattle near a switching point

Symptoms

  • DC fast charging aborts at random
  • Lock status message that appears and clears again
