P0DA1 is the high-side fault of the lock position feedback: the signal stays near its upper limit, which points to an open circuit somewhere in the sensor loop rather than a grounded wire. In the 2023 Outlander PHEV, Mitsubishi sets it in the PHEV-ECU when the supply is on and a high input from the lock position reading is seen. The test steps reveal the likely weak spots: terminal 1 of the lock actuator connector must have a ground path of no more than 2 Ω, terminal 2 must show battery voltage, the signal line to the PHEV-ECU must be intact, and the sensor in the inlet harness must read 16.8 kΩ within 5 percent. A failed ground, a broken wire or an open sensor therefore all end here. Mitsubishi's warning lamp table does not list it. The low counterpart is P0DA0.

Likely causes

Ground connection of the lock actuator connector interrupted
Open signal line between inlet harness and PHEV-ECU
Position sensor in the inlet harness open or far above 16.8 kOhm
PHEV-ECU input defective

Symptoms

  • Charging plug lock not confirmed, DC charging refused
  • Charging system message, no MIL documented
