P0DA1 code meaning
Battery Charger A Coupler Lock Position Sensor Circuit High
What P0DA1 means
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.
P0DA1 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0DA1
- Charging plug lock not confirmed, DC charging refused
- Charging system message, no MIL documented
Common causes of P0DA1
- Most likelyGround connection of the lock actuator connector interrupted
- PossibleOpen signal line between inlet harness and PHEV-ECU
- PossiblePosition sensor in the inlet harness open or far above 16.8 kOhm
- Less likelyPHEV-ECU input defective
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0DA1 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| A1 | The exact fault in that area. |
What to do next
- Note P0DA1 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0DA1
What does P0DA1 mean?
P0DA1 means "Battery Charger A Coupler Lock Position Sensor Circuit High". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P0DA1?
P0DA1 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0DA1 fail an emissions test?
P0DA1 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P0DA1 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will P0DA1 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
