This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with the temperature sensor that checks how hot the battery charger plug is getting. It's saying the sensor is reading too high.
The P2E4D code is triggered when the vehicle's onboard diagnostics system detects a high voltage or resistance in the circuit of the Battery Charger Coupler Temperature Sensor C. This sensor monitors the temperature of the charger coupler to ensure it doesn't overheat.
The Battery Charger Coupler Temperature Sensor C is responsible for monitoring the temperature of the charging coupler. If the temperature reading is higher than expected, it could indicate a problem with the sensor, wiring, or the coupler itself. The 'Circuit High' designation suggests that the signal voltage is higher than the expected range, which could be due to an open circuit or a faulty sensor.
• Check engine light on
• Charging issues with the battery
• Overheating of the charging coupler
• Reduced vehicle performance
• Faulty temperature sensor
• Damaged or corroded wiring or connectors
• Open circuit in the sensor wiring
• Faulty battery charger coupler
OBD-II: On-board diagnostics, a standardized system in cars for self-diagnosing and reporting.
Coupler: A device used to connect two pieces of equipment, in this case, the charger to the vehicle.
• Check for any visible damage to the charging coupler and wiring.
• Use a multimeter to test the voltage and resistance of the temperature sensor circuit.
• Inspect and clean any corroded connectors.
• Test the temperature sensor for proper operation.
• Replace the faulty temperature sensor.
• Repair or replace damaged wiring or connectors.
• Ensure the charging coupler is functioning correctly.
• Clear the code and test drive the vehicle to confirm the repair.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Chevrolet Volt
• Nissan Leaf
• Toyota Prius Plug-in
• Regularly inspect the charging coupler and wiring for damage.
• Ensure the charging equipment is kept clean and dry.
• Avoid overloading the electrical system.
Sensor Issue
• Do not ignore the check engine light.
• Avoid using the charging system until the issue is resolved.
• Consult a professional mechanic if unsure.
Check with your vehicle manufacturer as sensor issues may be covered under the powertrain or emissions warranty.
This code often appears in hybrid and electric vehicles due to the complexity of their charging systems.
Moderate – It should be addressed soon to prevent potential damage to the charging system.
Driving with a faulty charging system can lead to battery damage or reduced vehicle performance. Always ensure repairs are done by a qualified technician.
• Vehicle in a safe, dry environment
• Battery charger connected
The temperature sensor is typically located near the battery charger coupler, either within the coupler itself or in the immediate vicinity.
Q: Can I drive my car with this code?
A: It's best to avoid driving until the issue is fixed, as it could lead to further damage.
Q: How do I reset the check engine light?
A: After repairing the issue, you can use an OBD-II scanner to clear the code and reset the light.
