P2004 Fault: Intake Manifold Runner Control Stuck Open - 2009 Dodge Avenger Repair Guide
I'm currently experiencing a P2004 diagnostic code on my 2009 Dodge Avenger, which indicates that the intake manifold runner control is stuck in the open position. I've managed to turn off the MIL light manually, but this does not resolve the underlying issue. I'm wondering whether the runner rod itself can be replaced independently—since I've already had the runner control module (also known as the manifold flow valve controller) replaced. I'd prefer not to replace the entire intake manifold assembly. Can anyone confirm if a standalone replacement of the runner rod is possible or recommended? Any insights would be greatly appreciated.
The P2004 code stands for: INTAKE MANIFOLD RUNNER CONTROL STUCK OPEN. The Powertrain Control Module (PCM) detects that the position feedback from the Manifold Flow Valve Position Sensor is outside the expected range, either due to a failure in adaptation or after a non-volatile memory reset. A key point: Was the adaptive memory cleared when the valve was replaced by a Dodge OEM part? Adaptive values are typically reset by removing the negative battery cable—this step is often overlooked during repairs. While the code may seem serious, it could also stem from a wiring or sensor circuit issue. A thorough inspection of the electrical connections and sensor signals is recommended before assuming mechanical failure.
