OBD Code P2023 - Intake Manifold Runner Position Sensor/Switch Circuit Intermittent Bank 2

<<See All OBD Codes

Don’t worry if the P2023 code has been set in your vehicle, we have all the information you need to resolve it. This OBD-II trouble code is a generic one and is set when an error is noted with the intake manifold runner control circuit in bank 2. The number 2 cylinder is present in bank 2. The Powertrain Control Module sets this code when it receives voltage readings that show that the runner flaps are not in the correct position. At times this code is also set when there’s an abnormal voltage reading goes from the intake manifold to the runner control solenoid. Read on to know more about this error code and how to diagnose it correctly.

The Powertrain Control Module is responsible for monitoring the position of the intake manifold runner flaps. It does this by relying on the voltage signals that come in from the mass airflow sensor as well as the barometric pressure sensor. When these runner flaps are noted to not be in the correct position the PCM will set P2023 code. The intake manifold runner allows air to pass at higher Rotations per minute through the intake. When the Intake manifold doesn’t function as requested the P2023 code will be set. This is the reason this code is also defined as a Intake Manifold Runner Position Sensor/Switch Circuit Intermittent.

What causes this problem with the Intake Manifold Runner Position Sensor/Switch Circuit Intermittent Bank 2?

  • The intake manifold runner control solenoid is not working properly
  • The manifold runner flaps have become contaminated by carbon
  • Defect in the mass air-flow sensor
  • Barometric pressure sensor is faulty
  • Damages to the electrical components like wires, circuits, fuses, connectors etc.
  • Vacuum lines and hoses present in the intake manifold system have become disconnected or damaged
  • Malfunction of the PCM

Easy Diagnosis Of Engine Error OBD Code P2023

Here are some steps which you should follow in order to diagnose the P2023 fault code:

You can use the standard OBD scanner to resolve this code. Connect it to the vehicle diagnostic port and retrieve all the codes and don’t forget to freeze frame the data. Any additional codes if present prior to the P2023 will have to be sorted out first, as they could’ve been the reason this OBD code was set in the first place. Next it’s time to reset the trouble codes, and test-drive the vehicle to see if the P2023 code returns. If it does, then you will have to continue the diagnosis, if not then there may be an intermittent condition.

Move on to visually inspecting all the electrical components for any damages. You may find blown fuses, burned or corroded connectors, bent pins, short wires etc. Make sure you also check the vacuum lines and hoses for any blockages, or damages. Repair or replace everything as needed. Once these have been sorted, you can move on to testing the manifold runner flaps. This is done by operating the intake manifold runners via the OBD-II code scanner, when the runners are activated check if they’re opening and closing as needed. If that’s not the case you will have to check the voltage and ground signals of the intake manifold runner control solenoid. Any malfunctions noticed should be repaired or replaced as per need. However if you find that the runner is actually working fine, then there may be carbon buildup on the runner flaps. Check for that and also inspect the mass airflow sensor as well as the barometric pressure sensor. It is very important to pause inspection after each repair or replacement is made, this is to ensure that the repairs have been successful.

Common Mistakes When Diagnosing the P2023 Code

  • Not following the diagnostic steps in order or correctly
  • Erroneously replacing the intake manifold runner control solenoid when the issue is with the runner flaps
  • Hastily concluding an issue with the PCM
