Error Code P2117: What It Means & What To Do?

<<See All OBD Codes

The reduced performance of the engine is also known as the throttle/pedal position sensor ‘F’ minimum stop performance. The valve opening of the throttle is in turn controlled by the electronic throttle control system. By pressing the accelerator pedal, the PCM will receive a signal from the accelerator pedal position sensor as to how much power the driver expects from the engine. On the command of the PCM, the throttle plate will then open accordingly. P2117 error will be set if the malfunctioning of the ETCS is found by the PCM. Finally, the engine will be pushed into ‘limp home mode’ by the PCM where the power that is available will be limited so as to avoid unnecessary acceleration.

One of the important thing with respect to P2117 error is to check the operation of the VCT solenoid. The VCT solenoid can either be sticky or it can be stuck due to contamination. You can always verify the particular repair manual to carry out the component test for the VCT unit.

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

• The TPS or PPS might be malfunctioning.
• An open or shorted circuit might exist between the TPS, PPS, and PCM.
• The electrical connectors might be eroded.
• The DBW actuator motor might be faulty.

1. Engine Wiring Connectors – Do you find any cuts or leaky areas? Then it’s high time to replace the engine wiring connectors as they cause malfunctioning of the vehicle.
2. Pedal Position Sensor – Hesitation of the vehicle to move when the driver presses the pedal position sensor shows that it is defective. Repair or replace it with a new pedal position sensor.
3. Throttle Position Sensor – The throttle position sensor can turn out to be damaged if the vehicle fails to shift up. Get rid of the damaged TPS immediately.
4. Engine Light – The emission will increase if there is no proper amount of fuel to the engine which will likely damage the engine light. Fix it quickly so that the vehicle functions normally.
5. Engine Control Module – The behavior of your engine will be very erratic if the ECM is faulty or broken. Get it fixed or replaced as soon as possible.
6. Powertrain Control Module – Does your engine turn off without any reason? Then it’s a high time to replace your PCM as it can be faulty.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow diagnosing the problem that triggered a P2117 code to be stored:

• To correctly diagnose this error code, you will need various instruments.
• A DVOM, an oscilloscope, and a scanner can be highly helpful in performing a correct diagnosis.
• A manufacturer’s service manual will be essential.
• Carefully check the wires and connectors.
• The damaged wires, connectors, and other components have to be separated and repaired.
• After each successful diagnosis, recheck the system. Attach a scanner to the vehicle if every component is in proper working conditions and the retrieve both the stored codes and freeze frame data.
• This is highly helpful to find if there are any irregular conditions which made this error code to get stored in the vehicle.
• Clear all codes and retest the vehicle to see if any error has occurred.
• This will help you to know if the condition was irregular. Clear all codes and retest the vehicle to see if an error appears again.
• The condition will be erratic if the code does not show up instantly.
• In one such situation, you have to worsen the condition of the vehicle before proceeding for further diagnosis as this is a challenging task.
• This code is applicable to electronically controlled throttle body which is also called as drive-by-wire throttle body.
• The accelerator pedal arm which has a sensor will send a voltage signal to PCM, where the throttle body will open, or close based on the command.
• The throttle actuator is activated by the voltage signal from the PCM in the path which is needed to change voltage levels and polarity.
• When the throttle actuator motor turns, a gear in the throttle body will turn, which is engaged with a large gear.
• The ratio change will allow the plate to open slowly, quickly, suddenly or progressively based on the controller’s commands.
• Start testing the electrical connector of the throttle position sensor.
• Use a DVOM to verify the voltage and ground signal by separating the connector from the sensor.
• Yo must find a 5-volt reference signal and battery ground.
• For exact wiring diagrams and connector views, verify the manufacturer’s service manual.
• If there is no reference voltage or ground, separate the PCM as well as its related connectors and carry out a resistance and continuity test.
• Replace the shorted or open circuits as needed.
• Ensure a proper diagnosis is done by test driving the vehicle and clearing the error codes.
• Use an oscilloscope and check the pedal sensor operation if the voltage and ground signal agrees with the manufacturer’s specification.
• Examine if there are any glitches, issue of voltage or abnormalities.
• Alter the throttle pedal position sensor if required.
• Ensure a proper diagnosis is done by test driving the vehicle and clearing the error codes. You will find the PCM as well other controllers to be faulty if the TPP sensor and its related circuit compromises with manufacturer’s specification.
• Replacement of the controller has to be done by a professional mechanic.
• With the help of a scanner start the motor and check for voltage and ground signal at the connecting place of throttle actuator control motor.
• If it’s not available, detach the connector from the PCM as well as its connected controllers and carry out a continuity and resistance test for each circuit.
• Fix the open, shorted or detached circuits as desired.
• Ensure a proper diagnosis is done by test driving the vehicle and clearing the error codes
• If you find both the voltage and ground signal at the joining of the throttle actuator control module while starting the motor by using a scanner, replace the motor, ensure a positive repair is done by clearing the codes.
• Many automakers provide service parts for drive-by-wire throttle bodies.
• You must also change the throttle body which also comprises the actuator and TPS.
• You must also change the pedal sensor along with the throttle body.
• For a particular recommendation by the manufacturer, you must check the vehicle service manual.
• This situation can be easily handled by the professional technician as there are huge circuits involved.
• They will use a specialized scanner called Autohex to quickly find the error than normal scan tools.
• Removing every pin of the CAN bus one by one and testing them, might be time-consuming and too costly.
• You can always choose to install a memory saving device in your vehicle in case the PCM and other module fails and needs reprogramming.
• You can clearly see the pin values and operation of the control modules in the scanner.
• Apart from this, the circuit problem is also clearly monitored without any risk.
• If you come across any open or shorted circuits or any connectors which are broken, then it must be fixed immediately.
• Each time a repair is done, double check the entire process to make sure it’s successful.
• Inspecting thousands of individual circuits will require a proper diagnostic process with a DVOM.
• Misplacing even a single probe can abolish every costly module and you have to reprogram the system.
• This can be figured out by performing a continuity test where you need about 40 hours for the process depending on your vehicle.
• Few applications will require about different control modules were inspecting every wires and connector is necessary.
• This error code occurs often if the system ground is broken or damaged.
• The divergences of the ground system can be easily found with an auxiliary cable.
• Once everything is checked, the hanging ground straps, loose cable, and wires must be fixed.
• A damaged connector can give rise to this error code which further increases resistance. Do a continuity test with the help of the necessary diagrams, a DVOM and pinout charts and check the individual controllers and connectors.
• Compare your value along with the manufacturer and if you find any error fix it.
• The best advice is to replace the broken wires than trying to take away the complicated circuits which are quite risky.

Common Mistakes When Diagnosing the P2117 Code

• The throttle control motor is damaged.
• The accelerator pedal position assembly is defective.
• Broken PCM.
• The electrical wire causes some problem.
