This code means that the car's computer has detected a problem with the electric part that helps start the car. It's like a sensor is telling the computer that something is too high when it shouldn't be.
The P1E0B code is triggered when the vehicle's control module detects a high voltage condition in the current sensor circuit for the starter generator's Phase U.
The P1E0B code indicates an issue with the high voltage starter generator's Phase U current sensor circuit. This sensor is responsible for monitoring the current in one of the phases of the starter generator. A 'high' signal suggests that the sensor is reporting a higher than expected voltage, which could be due to a sensor fault, wiring issue, or a problem with the starter generator itself.
• Check Engine Light is on
• Vehicle may not start
• Reduced power or performance
• Faulty current sensor
• Wiring issues or poor connections in the circuit
• Malfunctioning high voltage starter generator
OBD-II: On-Board Diagnostics, a standardized system for self-diagnostics and reporting in vehicles.
Starter Generator: A component that combines the functions of a starter motor and an alternator in hybrid and electric vehicles.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connections to the current sensor.
• Test the current sensor for proper operation.
• Replace the faulty current sensor.
• Repair or replace damaged wiring or connectors.
• Replace the high voltage starter generator if necessary.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Chevrolet Volt
• Cadillac ELR
• Toyota Prius
• Regular maintenance checks
• Ensure all electrical connections are secure
• Avoid overloading the electrical system
Sensor Issue
• Have the vehicle inspected by a professional.
• Avoid driving the vehicle until the issue is resolved.
Check with your vehicle manufacturer for warranty coverage on the starter generator system.
This code is common in hybrid and electric vehicles with high voltage systems, often related to sensor or wiring issues.
Moderate – Address the issue soon to prevent potential starting problems.
Driving with this code active may lead to starting issues or reduced performance. It is recommended to address the issue promptly.
• Vehicle in 'On' position without starting
• Access to the vehicle's electrical system
The current sensor is typically located near the high voltage starter generator, often in the engine compartment.
Q: Can I drive with a P1E0B code?
A: It's not recommended to drive with this code active, as it may lead to starting issues or reduced performance.
Q: How do I reset the P1E0B code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, it should not return.
