What it means
The charge port door A open request switch circuit reports a fault. Operator request for charge port unlocking is unreliable.
At a glance
- Usually lights the check-engine light
How it works
The charge port door open request switch tells the vehicle when the driver requests that the charge port door unlock. This code sets when the switch circuit signal is faulty, making the door release request unreliable and potentially preventing charging from starting normally.
Common causes
Most likely first.
- Switch failed
- Wiring fault
Symptoms
- Charge status indicator shows fault
- Charging may not start or interrupts
- Slower-than-expected charge rate
How to diagnose it
- Use freeze-frame and charge-status data, then test the normal charge-port door release to establish whether the request is absent or intermittent.
- Inspect the charge port door switch, connector, and nearby wiring for damage, moisture, corrosion, or loose connections.
- Check switch circuit continuity and wiring for opens or shorts using the manufacturer's wiring diagram.
- Monitor the switch signal while operating it and compare the circuit response with the manufacturer's expected operation.
- If the switch and wiring test correctly, check the receiving module input and door release control circuit.
Common fixes
- Reconnect a loose charge port door switch connector.
- Repair damaged or corroded switch circuit wiring and terminals.
- Replace the charge port door request switch if it fails testing.
- Repair a confirmed fault in the receiving module input or door release circuit.
Can I keep driving?
You can generally drive if the port door is closed and the vehicle operates normally, but charging may not start or may be interrupted until the request circuit is repaired. Make sure the charging connector and port door are secure before setting off.
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.
