What it means
The charge port door A position sensor reports a position sensor circuit fault. Door state cannot be verified reliably.
At a glance
- Usually lights the check-engine light
How it works
The charge port door A position sensor reports whether the door is open or closed so the vehicle can confirm its state for charging and door control. This code sets when the sensor circuit itself has an electrical fault and the module cannot reliably read that state.
Common causes
Most likely first.
- Position sensor failed
- Wiring fault
Symptoms
- Charge status indicator shows fault
- Charging may not start or interrupts
- Slower-than-expected charge rate
How to diagnose it
- Read freeze-frame data and view the door A position status on a scan tool while moving the door between open and closed.
- Inspect the sensor, door linkage, connector, and wiring for physical damage, loose connections, or moisture.
- Check the sensor supply, ground, and signal circuit using the vehicle wiring diagram and compare results with the manufacturer's specification.
- Test the sensor output while the door moves to determine whether the fault is at the sensor or in the wiring.
- If the sensor and wiring pass, check the module input and connector before considering a control module fault.
Common fixes
- Reconnect or clean the position-sensor connector and repair damaged terminals.
- Repair an open, shorted, or damaged sensor wire.
- Replace a failed charge port door A position sensor.
- Repair the module input circuit if the sensor and wiring test correctly.
Can I keep driving?
Driving is generally possible if the door is closed and secure, but the vehicle may not confirm its position and could prevent or interrupt charging. Make sure the door is fully shut before driving.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
