User Submitted Video
When is the code detected?The Powertrain Control Module (PCM) detects that the position feedback of the manifold flow valve position sensor is not within range of adapted value learned during inplant initialization or after volatile memory reset.
P2004 Jeep DescriptionThe engine is equipped with an intake manifold flow control valve to promote maximum air/fuel atomization. The valve restricts air flow, causing it to tumble or swirl. The tumbling action helps ensure that the fuel and air mix thoroughly and burn faster. The intake manifold flow control valve and variable valve timing work together to improve fuel economy, idle stability, and emissions.
