What Does P3414 Mean?
The PCM detects that the cylinder 2 exhaust valve control system is not responding within expected parameters. The system is electrically functional but mechanical or hydraulic performance is degraded.
Common Causes
30%
Low engine oil level or incorrect oil viscosity affecting valve control hydraulics
25%
Restricted oil passages to cylinder 2 exhaust valve actuator
20%
Worn or sticking exhaust valve control solenoid with sluggish response
15%
Mechanical wear in valve control actuator or camshaft phaser
10%
Contaminated oil causing sludge buildup in valve control components
Diagnostic Steps
1
Step 1: Check engine oil level and condition; verify correct oil viscosity is being used per manufacturer specifications
2
Step 2: Monitor cylinder 2 exhaust valve control solenoid duty cycle and actual vs. commanded valve timing with scan tool
3
Step 3: Remove and inspect exhaust valve control solenoid for contamination, debris, or excessive wear
4
Step 4: Test solenoid operation with direct battery voltage and listen/feel for proper actuation
5
Step 5: If solenoid operates properly, inspect oil passages and valve control actuator for mechanical wear or restriction
Estimated Repair Cost
$200 - $1,200
Parts + labor, varies by vehicle and location
The PCM detects that the cylinder 2 exhaust valve control system is not responding within expected parameters. The system is electrically functional but mechanical or hydraulic performance is degraded.
The most common cause of P3414 (Cylinder 2 Exhaust Valve Control Circuit Performance) is: Low engine oil level or incorrect oil viscosity affecting valve control hydraulics
Typical repair costs for P3414 range from $200 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive but may experience rough running, reduced power, and poor fuel economy. Address promptly to prevent potential engine damage.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P3414 to identify the root cause.
