P0CCC

What it means

P0CCC means the control unit that monitors the charge port door has seen a fault in the circuit of the door A position sensor. The sensor reports whether the charge port door is open, closed or somewhere in between. The code sets when the signal is out of range, missing, erratic or does not agree with the door's commanded movement. The exact monitoring strategy and the wording of the fault vary by model.

Symptoms

• Charge port door will not open or close properly, or moves only part of the way
• Charge port warning message or light on the dashboard
• Charging cannot start or is blocked because the door position is unknown
• Dashboard shows the door as open when it is closed, or the other way round
• Charge port lighting or door motor behaves oddly or not at all

Possible causes

• Damaged, corroded or loose connector at the charge port door position sensor or door actuatorlikely
• Open circuit, short to ground or short to voltage in the sensor signal, supply or ground wiringlikely
• Faulty door position sensor or door actuator assembly with built-in sensorpossible
• Door mechanism jammed, frozen, dirty or physically damaged, so the sensor reading is not plausiblepossible
• Low or unstable 12 V supply causing a false circuit faultpossible
• Fault in the control unit that reads the sensor, or outdated software where the manufacturer has documented this as a causerare

How to diagnose

1. Read all stored codes and freeze frame data, noting whether the fault is current or history and whether other charging or body control codes are present
2. Check the 12 V battery condition and charging voltage, as low voltage can cause false circuit faults
3. Inspect the charge port door and surround for dirt, ice, debris, damage or a stiff mechanism, and operate the door by its normal control to see how it behaves
4. Visually inspect the sensor and actuator connectors and the wiring to the charge port for water ingress, corrosion, chafing, bent pins or poor terminal tension
5. Using live data, watch the door position reading while the door is operated and look for a missing, stuck or jumping value
6. Check the sensor supply, ground and signal circuits against the manufacturer's wiring diagram, using continuity and voltage checks with the vehicle in the correct safe state
7. Check for software updates or technical bulletins for this model and code before replacing any parts
8. Where high voltage components are involved in the charge port area, leave isolation and testing to a technician trained in high voltage systems

How to fix

• Clean, repair or replace damaged connectors and terminals at the charge port door sensor or actuator
• Repair or replace damaged wiring found to be open, shorted or chafed
• Replace the door position sensor or door actuator assembly if the sensor output is confirmed faulty
• Free, clean or replace a jammed or damaged door mechanism, then confirm that the door's travel is smooth and fully recognised
• Restore the 12 V battery or charging system if low voltage was the trigger
• Update the control unit software only if the manufacturer lists it as a fix for this fault, then clear the code and confirm it does not return
