Laymans terms

This code means that the car's computer has detected a problem with the switch that tells it when the charging door is open. It's like when a refrigerator light doesn't turn on because the door sensor is broken.

Explanation

The P0CC9 code is triggered when the vehicle's control module detects a low voltage signal from the charge port door open request switch circuit.

Technical description

The charge port door open request switch is responsible for signaling the vehicle's control system when the charge port door is opened. A 'circuit low' condition indicates that the voltage or signal from this switch is below the expected range, suggesting a potential wiring issue, switch malfunction, or a problem with the control module.

Symptoms

• Charge port door does not open or close properly

• Warning light on the dashboard

• Inability to charge the vehicle

Common Causes

• Faulty charge port door open request switch

• Wiring issues such as shorts or open circuits

• Faulty control module
