This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with the part that controls how the engine breathes on one side of the engine. It's like if one of your lungs wasn't working properly.
The VVL (Variable Valve Lift) system adjusts the engine's valve lift to optimize performance and efficiency. An open circuit in this system means there's a break in the electrical path, preventing it from working correctly.
P11A8 indicates an open circuit in the Variable Valve Lift (VVL) control system for Bank 2 of the engine. This could be due to a wiring issue, a faulty VVL actuator, or a problem with the engine control module (ECM). An open circuit prevents the ECM from controlling the VVL actuator, affecting engine performance.
• Check Engine Light is on
• Reduced engine performance
• Poor fuel economy
• Faulty VVL actuator
• Damaged or disconnected wiring
• Faulty engine control module (ECM)
VVL: Variable Valve Lift
ECM: Engine Control Module
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for Bank 2 VVL actuator.
• Test the VVL actuator for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the faulty VVL actuator.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Nissan Altima
• Infiniti G37
• Nissan Maxima
• Regular maintenance and inspection of engine wiring.
• Ensure proper engine oil levels and quality.
• Avoid harsh driving conditions.
Sensor Issue
• Have the vehicle inspected by a professional mechanic.
• Avoid driving aggressively until the issue is resolved.
Check with your vehicle manufacturer for warranty coverage on engine components.
This code has been associated with vehicles using advanced VVL systems, particularly in models from the late 2000s onwards.
Moderate – While the vehicle may still be drivable, it could lead to more severe issues if not addressed.
Ignoring this code may lead to engine damage and increased emissions, which could violate local emissions laws.
• Engine at operating temperature
• Vehicle in idle or low-speed conditions
The VVL actuator for Bank 2 is typically located on the side of the engine opposite the timing belt or chain.
Q: Can I drive with a P11A8 code?
A: It's not recommended to drive for extended periods with this code, as it can lead to further engine issues.
Q: How do I clear a P11A8 code?
A: After repairs, use an OBD-II scanner to clear the code from the vehicle's computer.
