This summary uses the existing diagnostic information shown in full below.
The car's engine has a special system that helps it run better, but it's not working right now. It's like a toy with a broken switch that can't be turned on.
The Variable Valve Lift (VVL) system is not reaching its full stroke position, causing the engine to enter a 'limp home' mode to prevent damage.
The P1062 code indicates that the Variable Valve Lift (VVL) system on Bank 1 is unable to achieve its full stroke position. This system adjusts the valve lift for better performance and efficiency. When it fails to reach the required position, the engine control module (ECM) triggers a limp home mode to protect the engine from potential damage.
• Reduced engine performance
• Check Engine Light is on
• Engine may run rough
• Faulty VVL actuator
• Wiring issues in the VVL circuit
• Defective 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 system operation using a diagnostic tool.
• Replace the faulty VVL actuator.
• Repair or replace damaged wiring.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Nissan Altima
• Infiniti G35
• Nissan Maxima
• Regular maintenance of the VVL system
• Timely oil changes
• Inspect wiring for wear and tear
Engine Performance
• Avoid driving aggressively until the issue is fixed.
• 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 issues in vehicles equipped with advanced valve lift systems, particularly in models from the early 2000s.
Moderate – The vehicle can still be driven, but performance is reduced and should be checked soon.
Driving with this code may lead to reduced performance and efficiency. It is advisable to address the issue promptly to avoid further damage.
• Engine at operating temperature
• Vehicle in park or neutral
The VVL actuator is typically located on the cylinder head of the engine, near the camshaft.
Q: Can I drive with a P1062 code?
A: Yes, but it's not recommended for long distances as it may lead to reduced performance and potential engine damage.
Q: What happens if I ignore the P1062 code?
A: Ignoring the code can result in decreased fuel efficiency and potential damage to the engine's valve train.
