Guide To P2115 OBD Error Code Solutions

<<See All OBD Codes

Reduced engine performance refers to the P2115 error code which is well-defined as the throttle position sensor ‘D’ minimum stop performance. The opening of the throttle valve is usually operated by the electronic throttle control system. As the driver presses the accelerator pedal, the PCM will receive a signal from the accelerator pedal position sensor as to how much power is expected by the driver from the engine. As per the PCM’s command, the throttle plate will open. P2115 error will be set if the PCM finds the ETCS to be malfunctioning and it will force the engine into ‘limp home mode’ to prevent unnecessary acceleration by restricting the available power.

This error indicates that the malfunctioning in a particular circuit of the throttle pedal position sensor has been identified by the PCM. 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 are some of the control modules that are included. If the PCM finds the malfunctioning of the throttle actuator control system, a compelled idle condition, a forced shutdown by the engine, or a forced power reduction will be initiated by some models.

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

• Faulty TPS or PPS.
• There might be a shorted circuit between the TPS, PPS, and PCM or it might be open.
• The electrical connectors might be corroded.
• The DBW actuator motor might be defective.

1. Engine Wiring Connectors – Do you find the flashing or the blinking of the check engine light? Then the engine wiring connectors can be faulty. Replace it with a new engine wiring connector from PartsAvatar.
2. Pedal Position Sensor – Malfunctioning of the pedal position sensor can take place if the vehicle experiences sudden jerking. Fix your defective pedal position sensor as soon as possible.
3. Throttle Position Sensor – Blinking of the check engine light indicates that the throttle position sensor faulty. Repair it quickly to avoid further troubles.
4. Engine Light – One of the symptoms for a defective engine light is the stalling of the car. Repair or replace the damaged light as soon as possible.
5. Engine Control Module – Is the performance of your engine very poor? Then your ECM can be defective. Get it replaced with a new ECM from PartsAvatar.
6. Powertrain Control Module – Overheating of the PCM can likely damage your PCM. Change it quickly by getting a new PCM from PartsAvatar.

Next important thing you need to know about are the common symptoms for this OBD error code P2115 with your fuel volume control.

Common Symptoms

• An absence of throttle response.
• Restricted or no acceleration.
• The engine might idle when it is permitted to stall.
• The vehicle will hesitate when you try to accelerate
• The malfunctioning of the cruise control.

Wish to correct this error code with your vehicle? Do you know what all you should do to make your car free from this code P2115? Well, don’t worry! We are here to guide you.

• Broken engine wiring connector needs replacement.
• Replacing the faulty ECM/PCM.
• Changing the damaged TPS and PPS.
• Altering the broken engine light.

Apart from the fuel injector, you might need to undergo few more replacements. You might need an engine wiring harness, body control module, injection pump, pcm module, ecm module, engine control unit, and many other parts. Where to get them from? Well, if you want quality parts, then we can prove to be your dream destination.

If you want to easily diagnose this fault code P2115, then all you have to do is to follow the steps which are mentioned below:

• Initially, for the diagnosis of a P2115 error, you have to carefully check the wires as well as connectors.
• Also, see if there is any possible damage or buildup of carbon in the throttle plate.
• Extreme carbon build up will hold the throttle plate to remain open which give rise to the P2115 error in the vehicle.
• As per the recommendation of the manufacturer, remove the carbon from the throttle body and fix the damaged wires/ components and then re-check the DBW system.
• To correctly diagnose, you need a scanner, a DVOM, and a reliable vehicle information source.
• Attach a scanner to the diagnostic port of the vehicle and recover every code that is stored.
• You can note down this information and store the freeze frame data as it can prove to be helpful if the condition is erratic.
• Test drive your vehicle again by clearing the codes to see if they reappear.
• If you find the error returning immediately, then there can be voltage spikes or variations between the TPS, PPS, and PCM which can be found with the help of scanner data stream.
• Narrow the data stream to show only related data for the quick response.
• If there is no spikes/variations, use the DVOM to recover original data at the sensor signal wires.
• Fix the positive test lead to the proper signal wire and the ground test lead to the ground circuit to recover the data with a DVOM, and then check the DVOM as you operate the DBW.
• As you actuate the throttle slowly, see for spikes in voltages from closed to open position.
• The voltage will be 5V at the closed and 4.5V at the wide open throttle, but you can always check for correct specification by using the vehicle information source.
• The sensor can be faulty if you find spikes or any other abnormalities.
• Test the operation with the help of oscilloscope.
• If the sensor works good, then remove the linked controllers and the individual circuits must be tested with DVOM.
• In order to know, which circuit to test and where to find them, you can always use the connector pinout charts and system wiring diagrams.
• Repair the system circuits if needed.
• You will find the PCM to be faulty or a programming error in PCM if every sensor and circuit work well.
• Replacement of the throttle body, throttle actuator motor, and all throttle position sensors will be recommended by some manufacturers as a single unit.

Common Mistakes When Diagnosing the P2115 Code

• The throttle control motor is defective.
• The accelerator pedal position assembly is damaged.
• Malfunctioning PCM.
• Issues with electrical wiring.
