Cylinder 9 Deactivation/Intake Valve Control Circuit Low
Code P3467 indicates that the powertrain control module (PCM) has detected a low voltage condition in the cylinder 9 deactivation/intake valve control circuit. This circuit is responsible for controlling the intake valve timing or cylinder deactivation solenoid for cylinder 9. A low voltage reading suggests a short to ground, open circuit, or faulty component, which can prevent proper valve operation and lead to engine performance issues.
01. Most Common Causes
- Faulty cylinder 9 deactivation/intake valve control solenoid
- Short to ground in the control circuit wiring
- Open circuit or poor connection in the harness
- Failed PCM (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Engine misfire or rough idle
- Reduced fuel economy
- Loss of power or hesitation
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to retrieve all stored codes and freeze frame data.
Step 2: Inspect the wiring and connector for cylinder 9 deactivation solenoid for damage, corrosion, or loose pins.
Step 3: Measure resistance of the solenoid; compare to manufacturer specs (typically 10-30 ohms).
Step 4: Check for voltage at the solenoid connector with key on; should see battery voltage. If low, trace circuit for shorts or opens.
Step 5: If wiring and solenoid are good, test PCM output or replace PCM as last resort.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as it can cause engine misfire, reduced performance, and potential catalytic converter damage. Have it diagnosed promptly.
How much does it cost to fix?▼
Diagnosis typically costs $50-$150. Repair costs vary: a solenoid replacement may be $100-$300, wiring repairs $50-$200, and PCM replacement $500-$1000.
