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 variable valve lift system on one side of the engine. It's like a safety switch turning on because something isn't working right.
The P1079 code is triggered when the engine control module (ECM) detects an overload condition in the variable valve lift (VVL) system on bank 2, which is one side of the engine.
Variable valve lift (VVL) is a technology used in engines to improve performance and efficiency by varying the lift of the engine's intake and exhaust valves. The ECM monitors the VVL system and if it detects an overload or fault condition, it sets the P1079 code for bank 2, indicating a problem with the system on that side of the engine.

• Regular maintenance and oil changes
• Inspect electrical connections periodically
• Use quality engine oil
Engine Performance
• Do not ignore the Check Engine Light
• Have the vehicle inspected by a professional
• Avoid hard driving until the issue is resolved
Check with the vehicle manufacturer for warranty coverage on engine components.
P1079 is a relatively uncommon code, typically associated with vehicles using advanced VVL technology.
Moderate – Address the issue soon to avoid potential engine damage.
Driving with a malfunctioning VVL system can lead to reduced performance and increased emissions.
• Engine at operating temperature
• Vehicle in drive or under load
The VVL solenoid is typically located on the cylinder head of bank 2, which is the side of the engine opposite the timing belt or chain.
Q: Can I drive with a P1079 code?
A: It's not recommended to drive for extended periods with this code, as it can lead to reduced performance and potential engine damage.
Q: What is bank 2?
A: Bank 2 refers to the side of the engine opposite bank 1, which is usually the side with cylinder 1.

Fitment Required · Vehicle-fitment part
Relevant when the fault points toward ignition-coil performance or cylinder-specific ignition issues.
Some ignition faults involve coil performance or cylinder-specific coil problems.
Match the coil to your engine and confirm the failed component before ordering.
