This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the part of the car that controls how the engine breathes on one side of the engine. It's like a switch isn't working right, so the engine can't 'breathe' properly.
The P117A code indicates an issue with the Variable Valve Lift (VVL) relay circuit on bank 2 of the engine. This circuit is responsible for controlling the lift of the engine's valves to optimize performance.
The VVL system adjusts the lift of the engine's valves to improve efficiency and performance. The relay circuit controls the activation of this system. When the circuit fails, it may lead to improper valve lift, affecting engine performance.
• Check Engine Light illuminated
• Reduced engine performance
• Poor fuel economy
• Faulty VVL relay
• Damaged wiring or connectors in the VVL circuit
• ECM (Engine Control Module) failure
VVL: Variable Valve Lift
ECM: Engine Control Module
• Use an OBD-II scanner to confirm the code.
• Inspect the VVL relay and circuit for damage or corrosion.
• Test the relay with a multimeter to ensure it functions properly.
• Replace the faulty VVL relay.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Nissan Altima
• Infiniti G35
• Nissan Maxima
• Regularly inspect wiring and connectors for damage.
• Ensure the relay is functioning during routine maintenance.
• Keep the engine control system updated.
Engine Performance
• Avoid driving the vehicle aggressively until the issue is resolved.
• Have the vehicle inspected by a professional mechanic.
Check with the vehicle manufacturer for warranty coverage on engine components.
This code has been associated with vehicles that use advanced valve timing systems to improve engine efficiency.
Moderate – While the vehicle may still be drivable, it can lead to reduced performance and efficiency.
Driving with a malfunctioning VVL system may not comply with emissions regulations and can affect vehicle safety.
• Engine at operating temperature
• Vehicle in a safe, stationary position
The VVL relay is typically located in the engine compartment, near the fuse box or ECM.
Q: Can I drive with a P117A code?
A: It's possible to drive with this code, but it's not recommended as it can lead to reduced performance and fuel efficiency.
Q: How can I prevent this issue?
A: Regular maintenance and inspections can help prevent issues with the VVL relay circuit.
