P2130 - OBD Trouble Code

<<See All OBD Codes

It is always an unsettling feeling when you have an OBD code set in your vehicle, especially when you don’t know what that means or how to resolve it. Well, good thing is that we have it all sorted for you, you can find all the information here along with diagnostic steps. The P2130 code is set by the PCM when it picks up an issue with any of the throttle pedal position sensor circuits. Depending on the vehicle, you may find that it gets forced into idle position or a forced shut down of the engine, this is especially possible if the PCM has recognized a malfunction of the throttle actuator control system. The “F” here refers to a particular circuit, sensor, or area of a particular circuit.

In your vehicle the Throttle Position sensor (TPS) send information about the throttle position to the PCM. This code is indicative that the vehicle computer i.e. the PCM has picked up a problem in any particular throttle position sensor circuit. Other modules that may also have picked up this issue include the body control module, the fuel injection control module, the turbo control module, transmission control module, the body control module, the anti-lock brake control module, the instrument panel control module, the anti-theft module, the cruise control module, etc. Whenever the PCM is able to detect a voltage that is not within the normal range prescribed by the manufacturer the P2130 code will be set.

What causes this problem with the Throttle Position Sensor/Switch F Circuit Malfunction?

• Throttle return spring sticking
• Corrosion of the MAP or TPS connector
• Chafing caused by misrouted harness
• Poor TPS
• Malfunctioning PCM
  

1. Throttle Position Sensor - This helps in monitoring the throttle position of the vehicle. A malfunction of this sensor can cause the P2130 code to set.

5. Accelerator Pedal Sensor - This sensor is responsible for transmitting the position of the accelerator pedal to the engine control unit PCM. Accordingly the vehicle will move. Having an faulty sensor can cause the P2130 code to set. It’s best to either repair or replace it and get rid of the code. You can buy required parts online at PartsAvatar Canada.
6. Engine Control Module - The ECM controls the fuel mixture, ignition timing, variable cam timing and emissions control etc, so if it’s not functioning properly it can result in the P2130 code setting. Try to repair or replace it as needed. PartsAvatar has a wide range of ECM available, order from the comfort of your home and have it delivered right to your doorstep.
   

It is vital 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 P2130 here:

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2130 code to be stored:

Find the OBD scanner for your vehicle, a digital volt/ohmmeter and an oscilloscope to be able to perform diagnosis. Apart from these tools you will also need your manufacturers service manual. Once you have all this ready, start off my simply running a visual inspection of all the wiring and connectors associated with this issue. Once you have spotted issues, proceed to repairing or replacing these damages, shorted, corroded wires or connectors. You may also find some being disconnected and components that may be beyond repair. Do the needful and move on to retesting the system to ensure success of the repairs/replacements done. If they all seem to be in good working condition now, you can connect the OBD scanner and record all the codes that are stored and freeze frame the date. Make sure you write in the order of occurrence, knowing these codes can help resolve issues that may be intermittent in nature. Now you can safely clear all the codes and take your vehicle on a test drive to see if the code resets or the vehicle enters readiness mode. If the code doesn't set, then it’s a sign that you may have an intermittent condition, these can prove to be challenging, and in most cases the situation needs to worsen before correct diagnosis can be made.

If you find that code has been reset, you can continue with the diagnosis, the P2130 code is applicable only to those vehicles that have an electronically controlled throttle body, they’re hence also referred to “drive by wire” throttle bodies.

There’s a sensor present on the accelerator pedal arm, which inputs a voltage signal to the PCM or related controllers, this signal commands the throttle body to be opened or closed, based on the conditions. The voltage signals from the PCM then activate the throttle actuator motor as per required by the changing voltage levels and polarity into the direction requested. When the motor turns, a gear in the throttle body which is meshed with a larger gear also turns. This ratio change is what allows the throttle plate to open quickly and suddenly or slowly and gradually as per the command of the controller. So you need to start testing at the throttle position sensor electrical connector, simply disconnect the connector from the sensor and use the DVOM to check voltage as well as ground signals. You should typically get a 5-volt signal and battery ground should also be there. To be able to find the exact position of these components, refer the wiring diagrams of your vehicle manufacturer.

After testing, if you have found no ground or voltage then you will have to disconnect the PCM connector as well as all the controllers related, and then perform the same test on all the circuits. As per requirement, repair or replace any damaged circuitry. Now you can clear the codes and again test-drive your vehicle and see if that has resolve the P2130 code. If you find that the voltage and ground signals are not in sync with the manufacturers prescribed specifications, then you will need to make use of the oscilloscope and monitor the operation of the pedal sensor. Be careful and observe any abnormal spikes in voltage, glitches etc. and replace the throttle pedal position sensor as needed. Now again, clear codes and go on a test drive to be able to conclude if the repairs have resolved the problem or not.

If you have found that both the throttle position sensor as well the related circuits are complying with the specifications of the manufacturer then you may mostly be dealing with a defective PCM or any other controller. Replacement of the controllers requires programming by a professional.

In some cases, you may need to replace the whole throttle body, this includes the actuator motor, and the throttle position sensor as well. Your mechanic may also recommend a replacement of the pedal sensor. You may also find that the issue is related to the Control Area Network (CAN) in such a case you will need a professional to sort it out. This code is rather complicated one and you may need a professional to manage the bulk circuitry that is involved in this problem.

Codes likes these can be cause due to defective or disconnected system grounds, in such a scenario an auxiliary ground cable can be used for diagnosis. You can also try to look for any loose or corroded electrical connectors which may increase circuit resistance and possibly cause the code to be stored. For this you can refer a CAN bus system wiring diagram and locate the wires and via DVOM test the continuity between individual controller connectors. Once you have all your findings compare them to the ones prescribed by your manufacturer and accordingly repair or replace the circuits.

Common Mistakes When Diagnosing the P2130 Code

• Failure of the Accelerator Pedal Position (APP) assembly
• Malfunction of the Powertrain Control Module (PCM)
