Cylinder 2 Exhaust Valve Control Circuit/Open
Code P3413 indicates an open or malfunction in the exhaust valve control circuit for cylinder 2. This circuit is part of the variable valve timing (VVT) system, which adjusts exhaust valve timing for optimal performance and emissions. An open circuit means the engine control module (ECM) detects a break or high resistance in the wiring or solenoid, preventing proper valve actuation. This can lead to reduced engine power, poor fuel economy, and increased emissions.
01. Most Common Causes
- Faulty exhaust valve control solenoid on cylinder 2
- Open or shorted wiring in the control circuit
- Corroded or loose electrical connector
- Failed engine control module (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Rough idle or misfire on cylinder 2
- Reduced engine power and acceleration
- Poor fuel economy
03. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm code P3413 and check for related codes.
Step 2: Visually inspect the wiring and connector for the cylinder 2 exhaust valve control solenoid for damage, corrosion, or loose connections.
Step 3: Test the solenoid resistance with a multimeter; compare to manufacturer specs (typically 6-12 ohms).
Step 4: Check for battery voltage and ground at the solenoid connector with key on engine off.
Step 5: If wiring and solenoid are good, test the ECM output signal using a scan tool or oscilloscope.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances. The issue can cause poor engine performance, increased emissions, and potential damage to the catalytic converter if left unfixed.
How much does it cost to fix?▼
Repair costs typically range from $150 to $400, including parts and labor. The solenoid itself costs $50-$150, and labor is 1-2 hours at $100-$150 per hour.
