Description of DTC code P2013

The PCM (Powertrain Control Module) electronically controls and adjusts the Intake Manifold Runner Control (IMRC) system. This is responsible for controlling the air in the intake manifold, cylinder head, and combustion chamber employing flaps that open and close commanded by an actuator. The position of these flaps is determined by the Powertrain Control Module depending on the driving needs of the engine.

If the Intake Manifold Runner Control Sensor-related circuit detects faulty voltage levels that are at excessive levels compared to those previously stored in the PCM memory, the P2013 OBDII diagnostic code will be stored.

Symptoms of fault code P2013

  • Check Engine lamp illumination.
  • Difficulty accelerating the vehicle.
  • Loss of engine power.
  • Poor fuel economy.

Causes of OBD2 P2013

The reasons for setting the P2013 OBD2 error code are usually:

  • Intake manifold actuator circuit wires could be bad.
  • The intake manifold actuator could be defective.
  • Manifold runners could be out of adjustment.
  • Intake Manifold Runner Control flaps could be blocked.

Possible solutions of the DTC code P2013

To troubleshoot the DTC P2013 OBDII perform the following steps:

  • Consult the Technical Service Bulletins (TSB).
  • Verify that the intake manifold wiring is in good condition. If you find damaged wires that cause an open circuit, make the necessary repairs.
  • Check that the IMRC system fins are not obstructed by carbon residue. If these are obstructed in such a way as to alter their operation, proceed to take the necessary measures.
  • A DVOM performs resistance tests on the IMRC Actuator to check if the voltage levels match those provided by the manufacturer. If the voltage levels are excessively high, check the wiring and repair or replace the damaged components.
