What Does P3413 Mean?
The PCM has detected an open circuit in the exhaust valve control system for cylinder 2. This means there is no electrical continuity in the circuit, preventing exhaust valve timing control.
Common Causes
35%
Disconnected or loose electrical connector at exhaust valve control solenoid
30%
Broken or severed wire in harness between PCM and cylinder 2 exhaust valve solenoid
25%
Failed exhaust valve control solenoid with open internal coil
8%
Corroded connector pins causing loss of continuity
2%
PCM connector terminal pushed out or damaged
Diagnostic Steps
1
Step 1: Visually inspect cylinder 2 exhaust valve control solenoid connector for proper engagement and secure connection
2
Step 2: Disconnect solenoid and measure resistance across solenoid terminals; should read 6-12 ohms (open circuit indicates failed solenoid)
3
Step 3: Check for continuity between PCM connector and solenoid connector on both control and ground circuits
4
Step 4: Inspect wiring harness for signs of damage, chafing, or breaks, particularly near heat sources and moving components
5
Step 5: Verify PCM connector pins are properly seated and making good contact
Estimated Repair Cost
$120 - $750
Parts + labor, varies by vehicle and location
The PCM has detected an open circuit in the exhaust valve control system for cylinder 2. This means there is no electrical continuity in the circuit, preventing exhaust valve timing control.
The most common cause of P3413 (Cylinder 2 Exhaust Valve Control Circuit/Open) is: Disconnected or loose electrical connector at exhaust valve control solenoid
Typical repair costs for P3413 range from $120 to $750, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive but may experience reduced performance and fuel economy. Prolonged driving may lead to engine damage from improper valve timing.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P3413 to identify the root cause.
