This summary uses the existing diagnostic information shown in full below.
The car's computer is having trouble controlling a part of the engine that helps it breathe better on one side of the engine.
The code P1054 indicates an issue with the Variable Valve Lift (VVL) control circuit on bank 2 of the engine. This system adjusts the lift of the engine's valves to optimize performance and efficiency.
P1054 is triggered when the Engine Control Module (ECM) detects a malfunction in the Variable Valve Lift control circuit for bank 2. This could be due to electrical issues such as a short or open circuit, or a failure in the VVL actuator or related components.
• Check Engine Light illuminated
• Reduced engine performance
• Poor fuel economy
• Engine misfires
• Faulty VVL actuator
• Open or shorted VVL control circuit
• Poor electrical connection in VVL circuit
• Faulty ECM
VVL: Variable Valve Lift
ECM: Engine Control Module
• Check for any other related trouble codes.
• Inspect the VVL actuator and wiring for damage.
• Test the VVL control circuit for continuity and proper voltage.
• Verify ECM functionality.
• Replace or repair the VVL actuator.
• Repair or replace damaged wiring or connectors in the VVL circuit.
• Replace faulty ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Nissan Altima
• Infiniti G35
• Nissan Maxima
• Regular maintenance of the engine and its components.
• Ensure electrical connections are secure and free from corrosion.
• Use quality engine oil to prevent sludge buildup.
Engine Performance
• Avoid heavy driving until the issue is resolved.
• Consult a professional mechanic for accurate diagnosis.
• Regularly check engine oil levels and quality.
Check with your vehicle manufacturer for specific warranty coverage related to engine components.
P1054 is commonly associated with vehicles that have advanced variable valve timing systems, which have become more prevalent in modern engines.
Moderate – While the vehicle may still be drivable, prolonged use without repair could lead to further engine damage.
Ignoring this code could lead to increased emissions and potential engine damage, which may not comply with local emission regulations.
• Engine at operating temperature.
• Vehicle in a safe and controlled environment.
The VVL actuator is typically located on the cylinder head of bank 2 of the engine.
Q: What is bank 2?
A: Bank 2 refers to the side of the engine that does not contain cylinder 1 in a V-type engine.
Q: Can I drive with a P1054 code?
A: It's not recommended to drive for extended periods with this code, as it could lead to engine damage.
