Guide To P2111 OBD Error Code Solutions

<<See All OBD Codes

The error code P2111 usually refers to the throttle actuator control system which is stuck open. Depending on the driver’s request for power, the throttle motor will open and close the throttle plate by allowing more or less air to pass through the engine. The engine computer controls the throttle motor. The P2111 error code will be set if there is any movement by the PCM from the throttle motor. The engine might also be pushed into ‘limp home mode’ by the PCM, thus limiting the power that is available from the engine to avoid unnecessary acceleration.

The definition of this code, in this case is very clear. The throttle is usually stuck open. It is very essential to know that the PCM will use a sensor in order to monitor the throttle plates position. The sensor would have failed but the throttle plate might be working correctly, thus reporting the inaccurate position to the PCM.

What causes this problem with the Throttle Actuator Control System Stuck Open?

• The throttle body might be defective
• Either the throttle plate or the linkage might be dirty.
• The throttle position sensor might be damaged.
• The accelerator pedal position sensor might be defective.
• Defective throttle actuator control motor.
• The connectors and the wires might be damaged or corroded.
• The PCM might be faulty.

1. Powertrain Control Module - You will likely face performance issue in your engine if the powertrain control module is faulty. Also, the engine may fail to start and there might be sparking issues. Replace your powertrain control module if you happen to witness these symptoms in your vehicle.
2. Throttle Position Sensor – The engine will keep stalling if the throttle position sensor is faulty. Get it fixed as soon as possible.
3. Throttle System – The vehicle will lack power if the throttle system is malfunctioning. Get it replaced with a new throttle system from PartsAvatar as soon as possible.
4. Throttle Pedal Sensor - If your vehicle hesitates to move when the gas pedal is pressed, then the throttle pedal sensor can be defective. Replacing it quickly can help you to get rid of the P2111 error code.
5. Throttle Actuator Control System – Does you engine hesitate to start? Then it’s high time to replace the throttle actuator control system as it might be defective.

We at Parts Avatar Canada care for our customers, and that’s why we will help you to diagnose P2111 code by listing out some major symptoms. They are mentioned below as follows:

Common Symptoms

• The PCM will push the vehicle into engine shut down mode if the throttle plate is stuck open.
• The motor will idle extremely high if the PCM continues to allow the motor to operate with opened throttle plate, by making it unsafe to drive and causes further damage to the engine.
• In most of the scenarios, the check engine light of the car will remain on and for safety reason the vehicle will go into engine shut down mode.

Learn the ways with which you can correct this trouble code P2111:

• Replacing the faulty throttle position sensor.
• The throttle system and the throttle body needs replacement.
• The faulty PCM should be fixed.
• Changing the damaged engine wires.

Don’t get tensed if you are still facing any of these issues as we care for our customers and that’s why we offer a good range of car throttle, throttle body cleaner, TPS sensor, clutch pressure plate, electronic throttle control, body control module, fuel throttle and a lot more. We are sure that now all your issues would be resolved.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2111 code to be stored:

• In order to begin with the diagnosis, the mechanic will make sure that the throttle plate is stuck open.
• The presence of carbon around the throttle plate can make it stick. You have to clean the throttle plate as well as the throttle body after every tune-up.
• The throttle body must be replaced. The throttle body is nothing but a unit of throttles that are electrically controlled.
• The TPS, the throttle plate, and the throttle valve motor together comprises the throttle body.
• If you find the movement of throttle plate along with the gas pedal, then you have to check for the signal to the computer from the TPS.
• This is actually done by looking at the scan data when the throttle pedal is depressed.
• If there is no reaction to the TPS data on the scanner to the input of throttle pedal, then you must carry out a pinpoint test at the TPS.
• In order to perform the pinpoint test, you will need a multimeter, where you can directly test the value of resistance or voltage at the TPS.
• The specific test for these procedures will vary as it is designed differently by each manufacturer for these systems.
• Similarly, when depressing and releasing the gas pedal, if the movement of throttle plate does not occur, then the mechanic will use a scanner to check every other data which is used by PCM so that the position of the throttle plate is calculated.
• Most of the times, if this condition exists, then there will be other codes set in the vehicle.

Common Mistakes When Diagnosing the P2111 Code

Performing the diagnosis for this error code can be quite confusing. In order to manage the throttle system, each manufacturer will have a different strategy. So it is very important that you take time to study as to how the system functions. Depending on one code, the mechanic can replace either one or more components. This will eventually turn out to be a mistake if each of the data and code is not considered closely. For example, if the throttle pedal position sensor is malfunctioning, it will be impossible for the PCM to know that the gas pedal is being pushed by the driver. If the mechanic loses this fact and if he misinterprets the throttle valve to be stuck, then the technician might end up replacing the throttle body assuming it to have caused problem whereas the actual problem may lie with the throttle valve which is not moving because the input is not received by the PCM from the throttle pedal sensor.
