P2020 - OBD Trouble Code

<<See All OBD Codes

Your car is not working as usual and you just found out that an OBD error code has been set? We are here to take away all your anxiety and help you understand the P2020 code and also give you ways to resolve it. This code is a generic code concerning the fuel and air metering, and auxiliary emissions control systems. It is set by the Engine Control Module when it is unable to detect correct manifold air pressure variation in your vehicle.

The ECM of your vehicle is able to determine the correct position of the intake manifold runners by using various sensor readings. This helps it in creating air turbulence in the intake manifold. Your vehicles Intake Manifold Runner Control (IMRC) is utilised for changing or controlling the airflow in the vehicle engines air intake system. When this code is set by the Powertrain Control Module (PCM) it’s a sign that an issue has been observed with the IMRC circuit in the engines bank 2. This would also mean that the intake manifold runner flaps are not in their correct position, or there’s a presence of voltage or resistance coming from the solenoid which is not within the manufacturers prescribed bracket.

What causes this problem with the Intake Manifold Runner Pos Sensor/Switch Circuit Range/Performance Bank 2?

• Faulty IMRC solenoid
• Deposits of carbon present on the manifold runner flaps
• Faulty throttle plates
• Defect in the IMRC valves, actuators or sensors in bank 2
• Failed ECM

5. Emission Control System - Is present to limit the discharge of noxious gasses coming from the internal combustion engine and other parts of the vehicle. Repair any damages or replace it from us. We ship across Canada.
6. Air Intake System - Performs the important task of letting air into the car engine. Ensure it works properly by repairing any problems you have noted and if needed go for a replacement. You can find what you’re looking for at PartsAvatar. We ship from our warehouses located across Canada, you can get your order in just few days!
7. Intake Manifold Actuator - Is responsible for informing the PCM about linkage and plate position. Sort out the P2020 code by repairing or replacing the actuator. You can easily order online and track your order till it reaches you.
8. IMRC Solenoid - If you have found any issues with the IMRC solenoid, simply repair or opt for replacement from PartsAvatar. We have no hidden shipping costs in our prices. Select form a wide range of brands and fitment.
9. IMRC Valve - If the valve is damaged it can not only cause the P2020 code to set but also, damage other connected components. Try to repair and see if that helps, otherwise go for replacement from PartsAvatar.
10. Throttle Plate - Is a butterfly valve that regulates air flow. Ensure its in good working condition. You can get rid of the P2020 code by repairing the damage or replacing it.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P2020 here:

Common Symptoms

• The check engine light is on
• Presence of vibrations in the engine
• RPM having fluctuations when idle
• Hesitation upon acceleration
• Lowered fuel efficiency

Here are some steps which you should follow in order to diagnose the P2020 fault code:

Connect your scanner to the diagnostic port of your vehicle and retrieve all the codes stored. Resolve the ones stored before P2020 and see if the code returns. Make sure all the codes and freeze framed and recorded for future reference if in case there’s an intermittent condition.

Once those codes are sorted you can start inspection of all the wires and connectors for any damages. They will have to be repaired or replaced accordingly. You can now proceed to inspecting all the hoses and vacuum lines for presence of damages or leaks, you will have to fix them as per extent of damage. Sometimes replacing is the best step so that other connected components don’t get damaged.

Now you can perform a check of the IMRC valves ad see if it moves properly, also remove the IMRC and see if there are any damages present. You should also test the movement of the plates/valves for any looseness or binding that may be present.

It is important to clear codes and do a test drive to see if the repairs or replacements have fixed the issue or not. Accordingly you can proceed with checking the rest of the parts for any faults that may be present.

Common Mistakes When Diagnosing the P2020 Code

• Replacing the parts that are not at fault like the runner flap when the issue is with the solenoid.
• Not following the diagnostic steps in order
• Not diagnosing the codes set prior to the P2020 code
