P2116 - OBD Trouble Code

<<See All OBD Codes

Are you looking for information regarding the P2116 error code? Then you have landed at the right place. A reduction in engine performance is usually known as the throttle/ pedal position sensor ‘E’ minimum stop performance. The electronic throttle control system, manages the opening of the throttle valve. A signal is sent from the accelerator pedal position sensor, when the accelerator pedal is pressed by the driver, to the PCM, by informing the PCM as to how much power the driver expects from the engine. The throttle plate will open on the command of the PCM. Any fault which is identified in the ETCS by the PCM will store the P2116 error code in the vehicle. Also, the engine will be forced into the ‘limp home mode’ by the ECM, restricting the power that is available from the engine to avoid unnecessary acceleration.

The error code refers to the improper functioning of a specific throttle pedal position sensor circuit which has been found by the PCM. The control module comprises of the PCM, transmission control module, body control module, anti-lock brake control module, instrument panel control module, fuel injection control module, turbo control module, anti-theft module, cruise control module, traction control module, proximity alert module, and the climate control module. Some models will need a compelled engine shut down, or a compelled reduction in power if the PCM finds the improper functioning of the throttle actuator control system.

What causes this problem with the Throttle/Pedal Position Sensor E Minimum Stop Performance?

• Damaged TPS or PPS.
• You might find a shorted circuit or there might be an opening between the TPS, PPS, and PCM.
• Corrosion of the electrical connectors.
• The DBW actuator motor might be broken.

1. Engine Wiring Connectors – A damaged engine wiring connector can cause an electrical problem in your car which will result in malfunctioning. Also, the fuel economy will get reduced as the flow of air will get blocked if the engine wiring connector is damaged. Fix it or replace it instantly.
2. Pedal Position Sensor – Does your engine surge without any reason? Then your pedal position sensor can be defective which needs replacement.
3. Throttle Position Sensor – The TPS can turn out to be defective if the acceleration by the vehicle is very low. Change your faulty TPS as soon as possible.
4. Engine Light – A decreased gas mileage is an indication of a damaged engine light. Replace with a new engine light from PartsAvatar at an affordable cost.
5. Engine Control Module – Engine stalling is one of the symptoms for a defective ECM which needs replacement as soon as possible.
6. Powertrain Control Module – Illumination of the check engine light proves that the PCM is defective or damaged. Get it fixed instantly by replacing it with a new PCM.

Have you ever wondered why is it so important to know the symptoms of the problem? Well, it is extremely essential to know the symptoms of the problem in order to detect it. Keeping this in mind, let’s throw some light on a few common symptoms of OBD error code P2116

Here are some steps which you should follow in order to diagnose this P2116 fault code:

• Various tools can be helpful when you try to diagnose this error code.
• A reliable scanner, DVOM, an oscilloscope can prove to be highly helpful to carry out this diagnostic procedure.
• You will be needing a service manual of the manufacturer or anything equivalent to it.
• Visually check every wires and connector.
• Fix the defective, detached or shorted wires, connectors, and other parts as necessary
• Recheck the system after every repair to make sure the diagnosis is successful.
• If every system appears to be in proper working condition, attach a scanner to the diagnostic connector and recover every freeze frame data and stored codes.
• In order to diagnose the erratic condition, this information can be highly helpful as you can know how this error code was stored.
• Clear the error codes and check again to see if the error appears.
• This can help you to know if there is any erratic signal stored in the vehicle.
• Clear the error codes and check again if they appear so it can help to know if any malfunction occurred.
• If the code does not instantly return, it is because of an irregular condition.
• Try to worsen this situation before proceeding with further diagnosis as it is a risky task.
• This code type is accessible only to electronically controlled throttle bodies which are also known as drive-by-wire.
• An input voltage signal is sent to the PCM by the sensor on the accelerator pedal which orders the throttle body to close and open based on the situation.
• In the required path, the signal of voltage from the PCM will initiate the throttle actuator motor by altering the polarity and voltage level.
• While turning the throttle actuator motor, it will, in turn, change the gear in the throttle body that is tangled with bigger gear.
• The throttle plate will open quickly, slowly, or unexpectedly based on the change in ratio and controller’s commands. Start checking the throttle position sensor electrical connector.
• Separate the sensor and connector and examine the voltage and ground signal by using a DVOM.
• You must be able to find a 5V reference signal and a battery ground.
• You can always trust the service manual of the manufacturer for connector views and perfect wiring diagrams.
• Disconnect the PCM as well as its controllers, if the reference voltage and ground are not found and carry out a resistance and continuity test on every circuit.
• Open or short circuits must be fixed as needed.
• Test drive the vehicle by clearing the codes to make sure the diagnosis is successful.
• If the throttle position sensors voltage and ground signals agree with the manufacturer’s specification, then examine the operation of the pedal sensor by using an oscilloscope.
• See if you find any irregular glitches, spikes or other malfunctions.
• Replacement of the throttle position sensor has to be done.
• Test drive the vehicle by clearing the codes to make sure the diagnosis is successful. The PCM can be damaged if the throttle pedal position sensor and related circuits comply with the manufacturer’s specifications.
• A well-trained mechanic must replace the controller as it requires reprogramming.
• As you start the motor with a scanner, check voltage and ground signals at the throttle actuator control motor connector.
• You have to test the individual circuit for resistance and continuity by disconnecting the PCM and its linked controllers if the voltage and ground signal is found.
• Repair every of the shorted, open or detached circuits as required.
• Test drive the vehicle by clearing the codes to make sure the diagnosis is successful.
• Replacement of motor must be done if both the voltage and ground signals are found at the throttle motor actuator.
• Test drive the vehicle by clearing the codes to make sure the diagnosis is successful.
• Service parts for ‘drive-by-wire throttle bodies is given by many of the automakers.
• Replacement of entire throttle body must be done which comprises of the actuator motor and the throttle position sensor.
• Replacement of pedal sensor along with throttle body will also be recommended.
• You can always check with the vehicle service manual if you need a particular recommendation by the manufacturer.
• Various sensors will send input data to the control modules and the system component and other control modules will receive output signals. It will be very difficult to diagnose by a professional mechanic if it turns out to be a CAN bus related condition.
• The best suggestion is to give it to the professionals as they know to handle them wisely as numerous circuits are included.
• They will use a specialized scanner called Autohex which identifies the error in the system quicker than other scan tools.
• If you remove and test every pin of CAN bus it will consume more time and money.
• The best idea is to install a memory saving device, in case you have to reprogram and the PCM and its controllers lose their memory.
• Every operation of the control module and pin values is clearly shown in the scanner. Also, while the engine is operating, it can clearly monitor the circuit problems without involving any risk.
• You have to fix the shorted or open circuits, damaged wires/connectors.
• Every time you repair, re-check if the process is successful. Once every component proves to be successful, connect a scanner and recover all codes that are stored and freeze frame data.
• If you continue the process with a DVOM, you have to inspect thousands of individual circuits.
• You may end up reprogramming the system or destroying every expensive module, even if you misplace one probe. This can be avoided by doing a continuity test, which requires about 40 hours based on your vehicle where you have to separate all control modules.
• Start your diagnosis as few applications will use 18 different control modules and check every wire, circuits, and connector.
• If there is any defective or broken system ground, you will find this error code most often.
• Using an auxiliary cable can be highly helpful as you can check the discrepancies of the ground system.
• Once the repair is done you will find the hanging ground straps, cables, and wires which needs fixation.
• If there are defective electrical connectors it can give chance for this error to be stored and it increases the resistance. Perform a continuity test between the individual controller and connector after you find the necessary wire diagram and pinout charts.
• Compare your values with the ones specified by the manufacturer and fix the error.
• Removing the complicated wire circuits is a tedious process. So it’s best to fix the defective wires.
