This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer found a problem with the system that turns off one of the engine's cylinders (cylinder 9) to save fuel. It's like a light switch that isn't working properly.
The engine control module (ECM) has detected a low voltage condition in the circuit that controls the deactivation of cylinder 9's intake valve.
P3467 indicates that the ECM has found a low voltage signal in the intake valve control circuit for cylinder 9. This could be due to an electrical issue such as a faulty solenoid, wiring problem, or a bad connection affecting the cylinder deactivation system.
• Check Engine Light is on
• Reduced engine performance
• Poor fuel economy
• Faulty cylinder deactivation solenoid
• Wiring issues or poor connections
• Faulty ECM
ECM: Engine Control Module
Solenoid: A device that converts electrical energy into mechanical action
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for cylinder 9's deactivation solenoid.
• Test the solenoid for proper operation and resistance.
• Repair or replace damaged wiring or connectors.
• Replace the faulty solenoid.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Silverado
• GMC Sierra
• Cadillac Escalade
• Regular maintenance and inspection of wiring harnesses.
• Ensure connectors are secure and free from corrosion.
• Use quality fuel to prevent deposits.
Engine Performance
• Avoid heavy acceleration until the issue is resolved.
• Schedule a diagnostic check with a professional mechanic.
Check your vehicle's warranty for coverage on engine components and electronics.
Cylinder deactivation issues have been more common with the introduction of fuel-saving technologies in modern engines.
Moderate – It should be addressed soon to avoid further engine performance issues.
Driving with this code may not be safe as it affects engine performance and fuel efficiency.
• Engine at operating temperature
• Vehicle at idle or light load
The cylinder deactivation solenoid for cylinder 9 is typically located on or near the engine cylinder head.
Q: Can I drive with a P3467 code?
A: It's possible to drive short distances, but it's best to have the issue diagnosed and repaired to prevent further damage.
Q: Does this code affect fuel economy?
A: Yes, a malfunction in the cylinder deactivation system can lead to reduced fuel efficiency.
