Description of DTC code P2076

The intake valve opens and closes to manage the flow of air entering through the intake manifold. It opens while accelerating, and closes when the engine idles.

The Intake Manifold Tuning (IMT) Valve Position Sensor/Switch receives voltage readings from the Barometric Pressure Sensor (BARO) and Mass Air Flow Sensor (MAF), which transmit information to tell the intake valve when to open or close. Likewise, the MAF Sensor and BARO Sensor provide the vehicle's computer with information about the position of the intake valve. If these voltage signals indicate that the intake valve is not within the expected position, the P2076 OBD2 fault code is set.

Symptoms of fault code P2076

  • Check Engine light illumination.
  • During low power, the engine torque decreases.
  • Engine idle.
  • MAF Sensor and BARO Sensor fault codes end up stored in the PCM.

Causes of OBD2 P2076

The reasons for the P2076 OBDII diagnostic code being set are:

  • The Intake  Manifold Tuning (IMT) Valve Position Sensor/Switch could be faulty.
  • Perhaps the IMT Sensor wires or connectors have been damaged.
  • The MAF sensor may have defects.
  • Possibly the BARO Sensor is in bad condition.
  • The intake valve could have excessive carbon buildup or be blocked.
  • PCM defective.

Possible solutions of the DTC code P2076

To fix the faults related to DTC P2076 OBD2 you should do the following:

  • Inspect the wires and connectors of the IMT Sensor, the MAF Sensor, and the BARO Sensor. Check that they are in good condition. Repair or replace any damaged cables or connectors. You should also verify that these sensors are compliant. Then proceed to clear the code.
  • Inspect the intake manifold and check it for carbon buildup. Clean it if necessary.
  • Check the power and voltage signal from the intake valve. These values should match those indicated in the manufacturer's specifications. Replace the valve if there are considerable differences.
  • Clear all diagnostic trouble codes from the PCM and complete a test drive to see if the P2076 trouble code returns.
  • If diagnostic fault code P2076 returns, inspect the intake manifold for high carbon buildup, as this is known to be a common cause of this fault code.
