Are you looking for the diagnostic procedure for P2620 error code? Then, keep reading further. Reduced engine performance is usually known as throttle position output circuit/open. This is an error code for the ECM which identifies that the throttle position closed output circuit is open and the closed throttle cannot be found. Some vehicles with a diesel engine will use this throttle valve so that it will help them to know as too when to run the catalyst regeneration.

The pedal position sensor/ switch comes as a part of the accelerator pedal assembly and you can find the throttle position sensor/switch on the throttle body of the intake manifold. The sensor will inform the engine control module as to how fast and quick the driver needs to reach the specific speed. If a problem is found by the sensor or the circuit for the sensor by PCM, an error will be stored. The speed will be reduced to 20 miles per hour by the PCM to safeguard the engine and due to the control module’s inability for the driver to precisely find the engine performance that is expected.

What causes this problem with the Throttle Position Output Circuit/Open?

• Broken throttle position sensor/switch.
• The harness of the throttle position sensor/switch might be shorted or it might have an opening.
• The electrical connection of throttle position sensor/switch might be bad.

1. Powertrain Control Module – The engine will fail to start or the fuel economy will be poor if the powertrain control module is faulty. Get them replaced as soon as possible so that you can get rid of the P2620 error code.
2. Throttle Position Sensor – The engine will keep stalling if the throttle position sensor is faulty. Get it fixed as soon as possible by getting a new one from PartsAvatar.
3. Throttle Body - Acceleration by the vehicle will be very slow if the throttle body actuator is faulty. Get it fixed quickly.
4. Accelerator Pedal Assembly - If the accelerator pedal assembly is faulty, then the acceleration of the vehicle after a particular time won’t take place. Fix the faulty accelerator pedal assembly soon.
5. Engine Control Module – You can easily find out that the engine control module in your vehicle is damaged if your vehicle faces issues like stalling or misfiring. Additionally, the behavior of the engine can be erratic. In one such scenario, it is always best to replace the faulty engine control module.
6. Throttle Control Motor – The fuel economy will be very poor if the throttle control motor is faulty. Repair the faulty throttle control motor as soon as possible
7. Throttle Actuator Valve – Any blockages in the throttle valve can cause malfunctioning of the vehicle which in turn reduces the performance of the engine. Repair or replace the damaged throttle valve as needed.
8. Throttle Pedal Sensor – Acceleration of the vehicle after a specified limit will be impossible if the throttle pedal sensor is faulty. Get it fixed to avoid P2620 error

Well, if you are looking to know about the common symptoms related to this error code P2620, we have worked out a small list to help you discover this error code with your vehicle.

Common Symptoms

• The error will be set in the ECM as a fault and the illumination of the check engine light will take place.
• In most scenario, the vehicle might not run at all and in some case, it might not run the catalyst regeneration.
• The catalyst might get clogged as the engine ECM will do not run the regeneration.

Once you know the symptoms of your vehicle’s problem, it becomes easy to detect it and get started with solving it. So, next on our list is a few common steps to correct this issue with your vehicle’s

• Firstly, you have to replace the throttle closed sensor,
• Check for possible faults with the throttle actuator valve and replace it.
• See if the wires and connectors to the sensor are faulty and replace it accordingly.

If you need parts to fix this issue, you no longer need to search for them. We at PartsAvatar Canada have an extensive range of auto parts PCM, throttle position sensor, throttle position switch, throttle body, accelerator pedal assembly, ECM, digital volt, ohmmeter, throttle control motor, throttle actuator valve in stock from you, ranging from all replacement parts to all interior and exterior parts.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2620 code to be stored:

• As a very first step, every of the ECM memory code must be cleared before visually inspecting the freeze frame data for the actual main problem so that the specific issue can be duplicated and the error can be resolved.
• Sometimes error might arise when you fail to clear the ECM error code once the codes are fixed.
• Failing to check the possible faults before altering any other replacement parts.
• Failing to check the bulletin of the manufacturer before replacing the faulty parts.
• Once you complete the diagnosis process, reset each of the codes and test drive the vehicle to make sure that the error does not come back again.

 Common Mistakes When Diagnosing the P2620 Code

• Malfunctioning of the powertrain control module.
•  Defective throttle control motor.
• Broken wires can cause some issue.
