The exact symptoms associated with diagnostic trouble code P2004 typically vary to some degree, on a case-by-case basis. See Also: Intake Manifold Leak Symptoms Symptoms of Code P2004 As a result, all advantages offered by the operation of such a system are negated. In the case of DTC P2004, a vehicle’s PCM has determined that the intake’s runners are not responding as expected, due to their actuator being stuck in the “open” position. If the actual position of the runner itself does not match that which is being called for by the PCM, an active DTC is logged. Some PCMs also rely upon data concerning the relative position of an engine’s EGR Valve.Īssuming that all input signals are accurately delivered, an engine’s PCM will call for the intake’s runners to be positioned in the best possible position for efficient air delivery.ĭuring this process, the PCM is receiving continual feedback, regarding the runner’s relative position. These inputs most notably include signals sent by an engine’s Mass Air Flow Sensor (MAF) and Barometric Pressure Sensor (BARO). These specialty manifolds feature indexable runners, which can be repositioned on-the-fly, in response to various operational inputs.Ī vehicle’s PCM determines the positioning of an engine’s runners within a variable intake manifold, based upon signals sent by several additional sensors. ![]() However, a significant number of today’s vehicles are now powered by engines that feature variable intake manifolds. These runners were positioned to use this air in the most efficient way possible. ![]() In the past, intake manifolds featured fixed runners, which were used to direct airflow intended for use in combustion. ![]() This, in turn, can negatively impact your engine’s operating efficiency, as intake air is unable to flow as desired by the PCM ( Powertrain Control Module). Therefore, the actuation of this runner cannot be completed as desired. Intake Manifold Runner Control (IMRC) Stuck Open Bank 1ĭiagnostic trouble code P2004 signifies that the actuator tasked with varying the position of an intake manifold’s runners is stuck in the “open” position.
