In this article, we will explore what the P2004 code means, its causes, symptoms, and how Mavyn can assist you in resolving it.

What is the P2004 Code?

The P2004 code is a diagnostic trouble code (DTC) that indicates a problem with the Intake Manifold Runner Control (IMRC) system. Specifically, it refers to the "Intake Manifold Runner Control Stuck Open (Bank 1)". This system is responsible for optimizing engine performance by controlling the airflow into the engine.

Causes of the P2004 Code

Several factors can trigger the P2004 code in your Ford Ranger. Here are some common causes:

1. Faulty IMRC Actuator: The actuator may fail, causing the runners to remain open.
2. Vacuum Leaks: Any leaks in the vacuum lines can affect the IMRC's operation.
