This can affect your vehicle's performance, fuel efficiency, and emissions. Understanding and addressing this issue promptly can save you time and prevent further complications. Here’s a detailed guide on how to diagnose and fix the P2004 error code in your Mazda CX-5.
What is the P2004 Error Code?
The P2004 error code is a diagnostic trouble code (DTC) that signifies a problem with the intake manifold runner control system. Specifically, it means that the IMRC valve in bank 1 is stuck in the open position. The IMRC system is designed to optimize air flow and enhance engine efficiency at different engine speeds.

Step-by-Step Guide to Diagnose and Fix the P2004 Error Code
Step 1: Verify the Error Code
- Use an OBD-II Scanner: Connect an OBD-II scanner to your Mazda CX-5’s diagnostic port to confirm the presence of the P2004 error code.
Step 2: Inspect the IMRC System
- Check for Physical Damage: Inspect the IMRC for any visible signs of damage or obstruction.

Step 3: Test the IMRC Actuator
