This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with how the intake valve for cylinder 2 is working. It's like one of the parts that lets air into the engine isn't doing its job right.
The P3499 code is triggered when the Engine Control Module (ECM) detects an issue with the deactivation or performance of the intake valve for cylinder 2.
The P3499 code indicates that the ECM has found a malfunction in the cylinder deactivation system, specifically affecting the intake valve operation of cylinder 2. This could involve the solenoids or mechanisms responsible for controlling the intake valve timing and operation.
• Check Engine Light illuminated
• Rough engine idle
• Decreased fuel efficiency
• Faulty intake valve solenoid
• Wiring issues in the solenoid circuit
• Mechanical failure in the valve train
ECM: Engine Control Module, the computer that controls engine functions
Solenoid: An electromechanical device used to control a valve
• Use an OBD-II scanner to confirm the code
• Inspect the wiring and connectors for the intake valve solenoid
• Test the solenoid for proper operation
• Replace faulty intake valve solenoid
• Repair or replace damaged wiring
• Inspect and repair mechanical components in the valve train
• OBD-II scanner
• Multimeter
• Basic hand tools

Engine Performance
• Avoid driving the vehicle until repaired to prevent further damage
• Consult a professional mechanic for a thorough diagnosis
Check with your vehicle manufacturer for warranty coverage on engine components.
Cylinder deactivation systems have been used to improve fuel efficiency by shutting down certain cylinders when full power is not needed.
Moderate – It should be addressed soon to prevent potential engine damage.
Operating a vehicle with a malfunctioning engine component can lead to further damage and is not recommended.
• Engine at operating temperature
• Vehicle in idle or low-load conditions
The intake valve solenoid for cylinder 2 is typically located on the engine near the cylinder head.
Q: Can I drive with a P3499 code?
A: It's not recommended to drive with this code as it could lead to further engine damage.
Q: What happens if I ignore the P3499 code?
A: Ignoring this code can lead to poor engine performance, increased emissions, and potential engine damage.
