This code means there's a problem with a part of the car's computer system that helps manage power. It's like when you have too many things plugged into an outlet and it trips the breaker. The car is trying to manage its power better.
The code indicates an issue with the control circuit for the Variable Valve Lift (VVL) load shedding relay. This relay helps manage electrical load distribution in the vehicle.
The P101E code is triggered when the Engine Control Module (ECM) detects a malfunction in the control circuit of the VVL load shedding relay. This relay is responsible for managing the distribution of electrical power to various components, especially under high load conditions. A fault in this circuit can affect the performance of the VVL system.
• Check Engine Light is on
• Reduced engine performance
• Electrical components not functioning properly
• Engine stalling
• Faulty VVL load shedding relay
• Wiring issues in the control circuit
• Faulty ECM
• Corroded or damaged connectors
VVL: Variable Valve Lift
ECM: Engine Control Module
• Use an OBD-II scanner to confirm the code.
• Inspect the VVL load shedding relay for faults.
• Check wiring and connectors for damage or corrosion.
• Test the ECM for proper function.
• Replace the faulty VVL load shedding relay.
• Repair or replace damaged wiring and connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Relay puller tool

Moderate
• Nissan Altima
• Infiniti Q50
• Nissan Maxima
• Regularly inspect electrical connections.
• Avoid overloading the vehicle's electrical system.
• Perform routine maintenance checks.
Electrical Circuit Issue
• Avoid using high-power electrical accessories until the issue is fixed.
• Consult a professional mechanic for accurate diagnosis.
Check if the vehicle's warranty covers electrical system repairs.
This code is relatively uncommon and often associated with specific models that use advanced VVL systems.
Moderate – It's important to address this issue to prevent further electrical problems.
Driving with electrical issues can lead to safety hazards. Ensure repairs are conducted by a qualified technician.
• Engine running
• Electrical load applied
The VVL load shedding relay is typically located in the vehicle's fuse box or relay panel.
Q: Can I drive with a P101E code?
A: It's not recommended to drive for long periods with this code active, as it can lead to further electrical issues.
Q: How can I reset the P101E code?
A: The code can be reset using an OBD-II scanner, but the underlying issue should be fixed to prevent it from returning.
