Guide To P2128 OBD Error Code Solutions

The accelerator pedal position sensor (APP) is a doorway to the powertrain control module that is utilized to ascertain the quantity of torque requested by the operator. In all 2 pedal position signals can be found in the sensor. The signals APP and APP2 have a positive slope (increasing angle, increasing voltage), although are offset and increase at variating rates. These 2 pedal position signals ensure the PCM receives a correct input even if 1 signal has a concern. The PCM calculates and determines whether if the signal is wrong (based on where it should be) deduced from other signals. The input is used whenever there is an error in one of the circuits. Between the PCM and the APP sensor assembly, there are 2 reference voltage circuits, 2 signal return circuits, and 2 signal circuits (a total of 6 circuits and pins). The PCM converts pedal travel degrees (rotary angle) in the pedal position signal. The software present alters these degrees to counts which then becomes the input to the torque - based strategy.

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

• A fault in the pedal position sensor
• A bad electrical connection in the pedal position sensor
• disconnected or short circuited wiring linked with the pedal position sensor
• A malfunctioning ECM

1. Accelerator pedal position assembly - An error in the accelerator pedal position assembly is likely to directly affect the APP sensor thereby increasing the risk of dangerous accidents (as the vehicle is no more in control of the driver). So we advise you to mend or restore it now. Don’t know where to look for? Parts Avatar to the rescue! Log in now.
2. Throttle control motor - Love travelling? But tired of these constant stalls? Also, observing a fall in the engine performance? Well, all this is likely to happen when your throttle control motor is damaged. Mend or restore now! Log into Parts Avatar, your one stop destination for all the problems.
3. Throttle position sensor - If you start experiencing engine misfires, stalling, or rough idling when the car is stopped, it should be taken as a sign of a faulty throttle position sensor. Now get your error code P2128 fixed with us at Parts Avatar. So? What are you thinking? We are just a click away!
4. Powertrain control module - Tired? Can’t comprehend the reason behind all the problems? A malfunctioning powertrain control module may lead to a poorly running engine. The operation and the fuel regulation of the system may also fail at times. The engine might choke as the PCM plays the role of determining the correct fuel mixture. So this essential unit if faulty should be changed immediately. Now get your PCM delivered right at your doorstep with Parts Avatar. What are you waiting for?
5. Throttle position sensor connector - A loose or short circuited throttle position sensor connector is dangerous for the throttle position sensor as it directly affects the overall performance of the sensor. Tune into Parts Avatar to get your new throttle position sensor connector at budget friendly prices.
6. Pedal position sensor - When the pedal position sensor is not functioning properly, it will also trigger problems with fuel efficiency. Apart from monitoring and applying throttle pressure to the throttle body, it also helps to stabilize the throttle control. Also, it is designed to take input from the driver, but steady the application of fuel pressure as it transmits the information from the ECU to the throttle body of the vehicle. All the functions tend to fail when the pedal position sensor is faulty. It is advised to get to get it changed or repaired as soon as possible.

Do you want to know the symptoms to OBD code P2128? If yes, then you have arrived at the right place. We at Parts Avatar have listed out few common symptoms associated with throttle position sensor/switch E circuit high input:

Common Symptoms

• Engine reluctance
• The check engine light blinking
• Low acceleration

Have a look at some ways with which you can correct the P2128 code:

• Measures should be taken to fix all defective wiring or electrical connections linked to the pedal position sensor
• The ECM should be reprogrammed or updated
• Replace or repair a damaged pedal position sensor

There is no need to get strained if your OBD code is still flashing up as we are here at your service. Have a look at our superior variety of accelerator pedal position assembly, throttle control motor, throttle position sensor, powertrain control module, throttle position sensor connector, pedal position sensor and many more. Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this P2128 fault code:

• A careful visual inspection should be performed of the pedal position sensor for any bad electrical connections, corrosion or raveling
• A scan tool should be used to look out for the data of the pedal position sensor while operating the pedal.

Common mistakes when diagnosing the P2128 code

Here we have listed a few mistakes that one should be careful of while diagnosing the error code:

Generally, there are two pedal position sensors utilized on vehicles manufactured after 2013. It is highly essential to differentiate the two using an apt diagram while diagnosing the error code (as it might lead to a wrong replacement at times).
