Code P1519 2001 Ford F150 Description

The Intake Manifold Runner Control (IMRC) is an electrically actuated system consisting of a motorized actuator with an attaching linkage for each housing on each bank. The linkage attaches to the housing butterfly plate levers. Each IMRC housing is an aluminum casting with two intake air passages for each cylinder. One passage is always open, and the other is opened and closed with a butterfly valve plate. The housing uses a return spring to hold the plates closed. The motorized actuator houses internal switches to provide feedback to the Powertrain Control Module (PCM), indicating linkage and plate position. Under about 3000 rpm, the vacuum solenoid will be energized. This will allow the manifold vacuum to be applied and the butterfly valve plates to stay closed. Above approximately 3000 rpm, the vacuum solenoid will be de-energized. This will allow a vacuum to vent from the actuator and the butterfly valve plates to open. The Diagnostic Trouble Code (DTC) sets when the IMRC is commanded open, but the IMRC monitor indicates close.

1. What does the OBDII code P1519 on a 2001 Ford F150 indicate?

Code P1519 indicates that the Intake Manifold Runner Control (IMRC) is stuck in the closed position. This system helps in controlling the flow of air into the engine, optimizing performance.

2. What are the common symptoms of code P1519 in a 2001 Ford F150?

Symptoms may include reduced engine performance, a rough idle, decreased fuel efficiency, and the engine light being illuminated.

3. What causes the P1519 code to appear on a 2001 Ford F150?

The P1519 code can be triggered by several issues including a faulty IMRC actuator, obstruction in the manifold runner, damaged linkage, or electrical problems like a bad wiring connection or faulty control solenoid.

4. How can I fix the P1519 code on my 2001 Ford F150?

Repairing the P1519 code may involve replacing the IMRC actuator, removing any obstructions in the manifold runner, repairing the linkage, or fixing any electrical issues such as replacing the solenoid or repairing wiring connections.

5. Is it safe to drive my 2001 Ford F150 with the P1519 code?

While you can drive your vehicle, it is not advisable as it might lead to poorer engine performance and increased fuel consumption. It's best to address the issue promptly to avoid potential further damage.

6. How do I diagnose the IMRC system for faults leading to the P1519 code on a 2001 Ford F150?

Diagnosing this issue typically involves checking the IMRC actuator and linkage for proper operation, inspecting for any mechanical obstructions, and testing the electrical components like the wiring and solenoid for faults.

7. Can a dirty intake manifold cause the P1519 code on a 2001 Ford F150?

Yes, a dirty or clogged intake manifold can prevent the IMRC from operating correctly and may cause the system to stick closed, triggering the P1519 code.

8. What tools are needed to diagnose and fix the P1519 code on a 2001 Ford F150?

Tools needed might include a diagnostic scanner to read the code and monitor IMRC operation, basic hand tools to access and repair the IMRC components, and possibly a multimeter for checking electrical connections and components.
