This code means there's a problem with the sensor that checks how much electricity is going through a part of the car that helps start the engine. It's like when a flashlight's battery sensor isn't working right, so you can't tell if the battery is full or empty.
The P1E11 code indicates an issue with the phase correlation of the current sensor in the high voltage starter generator circuit. This means the sensor is not correctly reading the electrical current flow.
The P1E11 code is set when the Powertrain Control Module (PCM) detects a discrepancy in the expected phase correlation of the current sensor for the high voltage starter generator. This can affect the vehicle's ability to start or manage electrical loads efficiently.
• Check Engine Light is on
• Difficulty starting the vehicle
• Reduced electrical performance
• Faulty current sensor
• Damaged wiring or connectors in the circuit
• Malfunctioning Powertrain Control Module (PCM)
PCM: Powertrain Control Module, the computer that controls the engine and transmission.
Current Sensor: A device that measures the flow of electrical current.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the current sensor for proper operation.
• Replace the faulty current sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Volt
• Chevrolet Malibu Hybrid
• Cadillac ELR
• Regular maintenance checks on electrical systems.
• Ensure connectors and wiring are secure and undamaged.
• Update vehicle software as recommended by the manufacturer.
Sensor Issue
• Avoid driving the vehicle until it is inspected by a professional.
• Schedule regular maintenance to prevent similar issues.
Check with the vehicle manufacturer for warranty coverage on electronic components.
This code has been more prevalent in hybrid and electric vehicles due to their complex electrical systems.
Moderate – It is advised to address this issue soon to avoid potential starting problems.
Driving with a known issue in the electrical system can lead to further damage or vehicle malfunctions.
• Vehicle at operating temperature
• Engine running with electrical load
The current sensor is typically located near the high voltage starter generator, often in the engine compartment.
Q: Can I drive with a P1E11 code?
A: It's not recommended to drive with this code active, as it can lead to starting issues or reduced electrical performance.
Q: How can I prevent a P1E11 code?
A: Regular maintenance and checks of the vehicle's electrical system can help prevent this code.
