What Does P1519 Mean?
The intake manifold runner control system has been detected as stuck in the closed position. This variable intake system failure prevents proper airflow optimization across different engine speeds.
Common Causes
40%
Carbon buildup causing mechanical binding of runner control valve
25%
Faulty intake manifold runner control actuator motor
20%
Broken or disconnected linkage/rod in runner control mechanism
10%
Failed intake manifold runner control solenoid
5%
Faulty position sensor on runner control valve
Diagnostic Steps
1
Step 1: Locate intake manifold runner control actuator and inspect for physical damage or disconnected linkage
2
Step 2: Command actuator operation using scan tool and listen/feel for movement
3
Step 3: Remove actuator and manually check runner valve movement for binding or carbon buildup
4
Step 4: Test actuator motor operation with direct power application if mechanical system moves freely
5
Step 5: Clean intake manifold runners and valves if carbon buildup is present
Estimated Repair Cost
$200 - $800
Parts + labor, varies by vehicle and location
The intake manifold runner control system has been detected as stuck in the closed position. This variable intake system failure prevents proper airflow optimization across different engine speeds.
The most common cause of P1519 (Intake Manifold Runner Control fault - Stuck Closed) is: Carbon buildup causing mechanical binding of runner control valve
Typical repair costs for P1519 range from $200 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle will experience reduced performance and fuel economy, particularly at certain RPM ranges. Safe to drive but performance will be compromised.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1519 to identify the root cause.
