Description of DTC code P2006 Generic

The IMRC (Intake Manifold Control) system manages and adjusts the airflow as it enters the intake manifold. The IMRC is controlled by the Powertrain Control Module (PCM), which opens and closes the system's flaps through a control solenoid to fit the cylinder port.

By channeling and restricting the airflow, a whirlpool effect is created which aids in the atomization of the air/fuel mixture. This results in reduced exhaust emissions and improved fuel efficiency and engine power.

When the diagnostic code P2006 OBDII lights up, it means that the IMRC system's controller circuit has detected that a flap in the bank 1 intake corridor is stuck in the closed position.

Symptoms of fault code P2006 Generic

  • The Check Engine light turns on.
  • Hesitation during acceleration.
  • A rich escape.
  • Fuel efficiency decreases.

Causes of OBD2 P2006 Generic

The reasons for the configuration of the fault code P2006 OBD2 are

  • There may be loose intake manifold corridors.
  • The IMRC Sensor solenoid may be defective.
  • The Intake Manifold Control Sensor is probably in bad condition.
  • Cables or connectors leading to damaged IMRC Sensor solenoid circuit.
  • Excessive carbon build-up on the IMRC flaps or in the intake manifold ports
  • The Manifold Absolute Pressure (MAP) Sensor may be defective.

Possible solutions of the DTC code P2006 Generic

Before establishing the DTC code P2006 OBDII, you must do the following:

  • Check the system of cables and connectors related to the system. Repair or replace any burned, worn, or corroded cables or connectors
  • Consult the vehicle information source for the corresponding tests to be performed on both the IMRC actuator solenoid and the actuator itself. If one of these components does not meet the manufacturer's specifications, you must replace it.
  • Make continuity, reference voltage, and ground signal tests for the circuit as a whole. Make the necessary corrections.
