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 power supply to a part of the engine that helps control how air gets into the engine. It's like if a toy's battery was too strong and made it act funny.
The P1058 code indicates that the voltage in the circuit that supplies power to the Variable Valve Lift (VVL) control motor on bank 2 is higher than expected.
The VVL system adjusts the lift of the engine's intake valves to optimize performance and efficiency. The control motor requires a specific voltage range to operate correctly. If the voltage is too high, it can indicate a wiring issue, a faulty motor, or a problem with the engine control unit (ECU).
• Check engine light is on
• Reduced engine performance
• Poor fuel economy
• Faulty VVL control motor
• Wiring issues such as shorts or open circuits
• Defective engine control unit (ECU)
VVL: Variable Valve Lift
ECU: Engine Control Unit
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the VVL control motor for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the VVL control motor if faulty.
• Reprogram or replace the ECU if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Nissan Altima
• Infiniti G35
• Nissan Maxima
• Regularly inspect and maintain engine wiring.
• Ensure ECU software is up to date.
• Avoid prolonged exposure to harsh environmental conditions.
Engine Performance
• Do not ignore the check engine light.
• Seek professional diagnostic services if unsure.
• Avoid driving aggressively until the issue is resolved.
Check if the vehicle is under warranty for powertrain issues, which might cover repairs.
This code is commonly associated with vehicles that have advanced valve timing systems, and it has been more prevalent as these systems have become more common.
Moderate – It should be addressed soon to prevent potential engine damage.
Driving with this code active may lead to increased emissions, which could violate local emissions laws.
• Engine at operating temperature
• Vehicle in a safe, stationary position
The VVL control motor is located on the engine, typically near the intake valves on bank 2.
Q: Can I drive with a P1058 code?
A: While you can drive with this code, it's not recommended as it may lead to reduced performance and efficiency.
Q: What is bank 2?
A: Bank 2 refers to the side of the engine opposite bank 1, which usually contains cylinder 1.
