P2133 OBD Error Code: Problem & Solutions

<<See All OBD Codes

You have just found out the reason to why your vehicle was in limp mode. Well, having an OBD-II code set can be rather daunting, especially if you don’t know what that means. The P2133 code is set by the Powertrain Control Module of your vehicle when it notices an issue with receiving necessary information from the Accelerator Pedal Position sensor. The engine stalls and enters into limp mode to keep the driver and the vehicle safe.

When you press the pedal the accelerator pedal opens and closes the throttle plate. This sensor is responsible for sending voltage signals to the PCM module to inform it about the position of the accelerator pedal. This voltage helps the PCM to understand whether the throttle place should be opened or closed. When the APP sensor is unable to communicate properly with the PCM, it will proceed to setting the P2133 code, and have the vehicle enter limp mode, the check engine light will also be turned on.

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

• Fault with the Accelerator Pedal Position sensor
• The harness of the APP sensor is open or shorted
• The wiring and other electrical connections are damaged or showing poor connection
• The connector of the APP sensor connector has become corroded or has damaged pins
• Defect in the throttle actuator control motor
• Defect present in the Throttle Position (TP) actuator
• The TP sensor is not functioning properly
• Malfunctioning PCM
  

1. Throttle Position Sensor - This is responsible for monitoring the throttle position of the vehicle. A malfunction of this sensor can cause the P2133 code to set. It is hence important to fix any damages via repairs or opt for replacement. Buy them online from PartsAvatar and buy good quality products, for a wide range of price from different brands all in one place.
2. Switch Circuit - The vehicle circuitry should always be working well, damages in the circuit system are the prime causes for OBD errors to set. In the case of P2133 you can easily solve your issues by repairing or replacing any issues with the switches and circuits. You can find the one compatible with your vehicle make and model at PartsAvatar, we have a large variety of TPS available on our website. You can order easily from the comfort of your home and have it delivered to you in just few days!
3. Powertrain Control Module - The brain of your vehicle has to always be in top condition, otherwise things can go haywire. If you have noticed troubles with the PCM, try to repair otherwise replace easily with Parts Avatar. You can avail free shipping on order s valuing over CAD 99$.
4. Accelerator Pedal Sensor - The APP sensor shows the position of the accelerator pedal to the engine control unit PCM. Accordingly the vehicle will move. Having a faulty sensor can cause the P2132 code to set. Try to repair or replace it as needed. PartsAvatar has a wide range of APP sensors , order from the comfort of your home and have it delivered right to your doorstep.
5. Engine Control Module - The ECM module is responsible for controlling the fuel mixture, ignition timing, variable cam timing and emissions control etc. of your vehicle so if it’s not functioning properly it can result in the P2133 code setting. It’s best to either repair or replace it and get rid of the code. You can buy required parts online at PartsAvatar Canada.

We at Parts Avatar Canada care for our customers, and that’s why we will help you to diagnose P2133 code by listing out some major symptoms. They are mentioned below as follows

Common Symptoms

• The Check Engine Light is on
• Inability to accelerate or poor acceleration
• Low engine power
• Black smoke emitted when starting the car
• Vehicle doesn’t start
• engine misfires
• Engine stalls

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

• Repair or replace the APP sensor
• Repair or replace the open or shorted APP sensor wiring harness
• Repair or replace all the damaged wiring and circuitry of the APP sensor
• Repair or replace the throttle actuator control motor
• Replacing TP sensor

Repair or replace the PCM, this will require some programming by a professional. However, if you face any issue then we have stocked a wide range of best priced Position Sensor, Switch Circuit, PCM, pedal position, ECM and more to help you out in fixing your car.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2133 code to be stored:

Start off by connecting your OBD scanner to the diagnostic port of your vehicle and retrieve all the codes stored. Freeze frame this data and start the inspection of the APP sensor connector for any damages. These damages could range from corrosion, bent pins, damages to the plastic components etc. You can now proceed to either repairing or replacing them as needed. Continue your inspection after these repairs, your focus now is the APP sensor wiring, look for any shorts, breaks or fraying of the wires. Repair or replace as needed.

Now you can clear the codes and perform a test drive to see if the code returns or the PCM enters readiness mode. If the latter happens it would mean that you either have an intermittent condition, or your repairs have successfully resolved the P2133 code. In case of an intermittent condition, you will have to wait for the issue to worsen before correct diagnosis can be made.

If you found that the code was reset, it’s time to check the voltage signal of the APP sensor. You can compare the readings with the specifications provided by your manufacturer. Make sure you match them correctly with your vehicle's engine, make and model. If you have noted the readings aren’t in the range needed, you will have to replace the APP sensor. Now clear the codes again and do another test drive to check if the P2133 code comes back. If you find that it still comes back, then it’s time to check the voltage of the TP sensor, if it’s not within the manufacturers prescribed range replace it or try to repair it. Do another test drive after clearing the codes, and if the code sets again, you have to now check the voltage signal of the TP actuator, ensure the motor is running while you perform this test. Compare the readings and see if they’re within the range needed, if not then you will know that the TP actuator is a faulty one and needs a replacement. However, if you find that everything is falling within the range then there’s an issue with the throttle actuator control motor. You can repair or replace it as needed; in this case you will also need to replace the throttle body assembly.

It is very important that you perform these steps in the order mentioned, if all is fine and readings are all within the range, then the problem is with the PCM. This is very rare and replacing a PCM also requires reprogramming by a professional. So, make sure you select a good mechanic who is experienced for this task.

Common mistakes when diagnosing the P2133 code

• Replacement of the APP sensor when the issue is with the throttle body assembly.
• Not inspecting the wiring and connectors before replacement of the APP and throttle body assembly.
