Code P2004 2008 Toyota Camry Description
The P2004 diagnostic trouble code (DTC) for a 2008 Toyota Camry indicates that the Intake Manifold Runner Control (IMRC) is stuck open on Bank 1. The IMRC system is designed to vary the length of the intake runners in the intake manifold to optimize airflow and improve engine performance at different RPM ranges. When the IMRC is stuck open, it can disrupt the proper air/fuel mixture entering the combustion chambers, leading to poor engine performance.
Common Causes of P2004 2008 Toyota Camry
- Faulty IMRC actuator
- Damaged linkage
- Wiring issues
- Vacuum leak
- Carbon buildup in the intake manifold
