The car's computer is having trouble figuring out where a part of the engine should start and stop moving. It's like if your toy robot's arm doesn't know where to begin or end its movement.
This code indicates a problem with the variable valve lift (VVL) system, which helps control how the engine breathes. The computer is detecting a mismatch between where the VVL should start and stop.
The P1064 code is triggered when the Engine Control Module (ECM) detects a discrepancy between the expected starting position and the actual parking position of the Variable Valve Lift (VVL) system on Bank 1. This could be due to a sensor issue, mechanical misalignment, or electrical fault.
• Check Engine Light is on
• Reduced engine performance
• Poor fuel economy
• Faulty VVL actuator
• Misaligned VVL components
• Defective position sensor
VVL: Variable Valve Lift
ECM: Engine Control Module
• Use an OBD-II scanner to confirm the code.
• Inspect the VVL actuator and related components for damage or misalignment.
• Test the VVL position sensor for proper operation.
• Replace or repair the VVL actuator.
• Realign VVL components as necessary.
• Replace the VVL position sensor if faulty.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Nissan Altima
• Infiniti G35
• Nissan Maxima
• Regular maintenance and inspections
• Timely replacement of worn components
• Using the correct engine oil
Engine Performance
• Avoid heavy acceleration until the issue is resolved.
• Schedule a service appointment with a qualified mechanic.
Check with your vehicle manufacturer; powertrain warranties may cover this issue.
This code is often associated with vehicles that have advanced variable valve timing systems and can occur as these systems age.
Moderate – While the vehicle may still operate, reduced performance and efficiency can lead to further issues if not addressed.
Driving with this code may not be safe as it can affect engine performance. Address the issue promptly to ensure vehicle safety and compliance with emission standards.
• Engine at operating temperature
• Vehicle in idle or low-speed conditions
The VVL actuator and position sensor are typically located on the engine's cylinder head, on the side of Bank 1.
Q: Can I drive my car with a P1064 code?
A: While you may be able to drive, it's not recommended as it can lead to reduced performance and potentially more damage.
Q: How does the VVL system affect my car?
A: The VVL system helps optimize engine performance and efficiency by adjusting the timing and lift of the engine's valves.
