P1D79 Code - Generator Motor I1 Current Sensor Circuit High Voltage
Quick Answer
The P1D79 diagnostic trouble code (DTC) indicates that there is a high voltage condition detected in the Generator Motor I1 Current Sensor Circuit. Common causes include Faulty Generator Motor I1 Current Sensor: A malfunctioning current sensor can cause inaccurate readings and trigger the high voltage condition, Wiring Issues: Damaged or corroded wiring in the circuit can disrupt the flow of current and lead to high voltage readings, Electrical System Malfunction: Problems in the vehicle's electrical system, such as a faulty voltage regulator, can contribute to the high voltage condition. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1D79 Description
The P1D79 diagnostic trouble code (DTC) indicates that there is a high voltage condition detected in the Generator Motor I1 Current Sensor Circuit. This code is typically found in hybrid vehicles with electric generators, such as hybrid electric vehicles (HEVs) or plug-in hybrid electric vehicles (PHEVs). The Generator Motor I1 Current Sensor is responsible for monitoring the current flow in the generator motor to ensure proper operation and efficiency.
Common Causes of P1D79
- Faulty Generator Motor I1 Current Sensor: A malfunctioning current sensor can cause inaccurate readings and trigger the high voltage condition.
- Wiring Issues: Damaged or corroded wiring in the circuit can disrupt the flow of current and lead to high voltage readings.
- Electrical System Malfunction: Problems in the vehicle's electrical system, such as a faulty voltage regulator, can contribute to the high voltage condition.
- Software Glitch: An issue with the vehicle's onboard computer or software can also trigger the P1D79 code.
Symptoms of P1D79
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Reduced Fuel Efficiency: High voltage in the generator motor circuit can lead to increased energy consumption, resulting in reduced fuel efficiency.
- Drivability Issues: The vehicle may experience hesitation, rough idling, or poor acceleration due to the high voltage condition.
- Electrical Malfunctions: Other electrical components in the vehicle may behave erratically or fail to function properly.
How to Fix P1D79
- Diagnose the Issue: Use a diagnostic scan tool to retrieve the trouble codes and perform a thorough inspection of the generator motor I1 current sensor circuit.
- Test the Current Sensor: Check the current sensor for proper operation and replace it if necessary.
- Inspect Wiring: Inspect the wiring in the circuit for any damage, corrosion, or loose connections, and repair or replace as needed.
- Check Electrical System: Verify the functionality of the vehicle's electrical system, including the voltage regulator, to ensure proper operation.
- Clear Codes and Test Drive: Clear the trouble codes from the vehicle's computer, and test drive the vehicle to confirm that the issue has been resolved.
Cost to Fix P1D79
The cost of repairing the Generator Motor I1 Current Sensor Circuit High Voltage issue can vary depending on the specific cause of the problem and the vehicle's make and model. In general, the cost of parts for this repair can range from $100 to $300, while labor costs can range from $100 to $300 as well. Therefore, the total repair cost can be estimated to be between $200 and $600. It is important to note that these are rough estimates, and actual costs may vary based on factors such as location, labor rates, and the extent of the repair needed. It is recommended to consult with a qualified mechanic or auto repair shop for a more accurate cost estimate.
