Guide To P2123 OBD Error Code Solutions

It is notable that the electronic throttle control system (ETCS) performs the task of regulating the throttle valve opening. The engine’s control module (PCM) receives a signal from the accelerator position sensor (APP) when the driver presses the accelerator pedal, the signal indicates the voltage of power that has been requested by the engine. In accordance with the PCM’ commands the throttle valve opens. When the PCM records a failure in the changing ability of the APP sensor, it stores the code P2123. Also, the PCM also puts the engine into the “limp home mode” thereby restricting the power available from the engine to stop the unwanted acceleration.

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

• A malfunctioning throttle body motor
• A damaged throttle position sensor
• A possible fault in the engine control module
• Corroded or disconnected wirings or connectors associated with throttle body motor

1. Throttle position sensor - The throttle position sensor (TPS), is part of the vehicle's fuel management system and helps ensure that a correct mixture of air and fuel is delivered to your engine. So a faulty one should be changed or repaired immediately. Tune into Parts Avatar now!
2. Switch circuit - See the error code P2123? Facing a lot of problems? Well, it could be due to a malfunctioning switch circuit. A low voltage and problems while starting or running the vehicle may be encountered too. Log into Parts Avatar for your new switch circuit today.
3. Intake manifold tuning valve - Weary and damaged intake manifold tuning valve can often be problematic. So to add some spark to your ride you definitely need the perfect quality Intake manifold tuning valve offered at Parts Avatar. Isn’t that just the perfect deal?
4. Powertrain control module - Because of a fault in the powertrain control module, downward emissions are likely to follow besides other issues like a sluggish engine crank, failure in the emission system etc. We advise you to get your faulty PCM changed now by simply logging into Parts Avatar.
5. Accelerator pedal position sensor - It is notable that whenever a problem with the accelerator pedal position sensor exists, the vehicle's ability to consistently accelerate or decelerate as directed by the driver is reduced. Mend or restore your APP sensor as soon as possible in order to avoid further complications caused by the error code P2123.
6. Engine control module - Hate these halts? Stuck? Can’t start the vehicle? All these problems occur due to a defective engine control module. Now get your new ECM delivered right at your doorstep with Parts Avatar.

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

• Firstly, the technician should start performing the diagnosis of the error code P2123 by locating the throttle body
• Now that you have located the throttle body, a visual inspection should be performed of the wiring and connectors associated to the throttle body motor and throttle position sensor
• If all seems to be working in order, the technician should next probe the throttle position sensor and throttle body motor utilizing the manufacturer’s recommended procedure
• If you fail to find the problem, we advise you to examine the engine control module to make sure that it is functioning in order.

Common Mistakes When Diagnosing the P2123 Code

Here we have listed a few common mistakes that should be avoided while diagnosing the error code P2123:

The most common mistake that is committed while performing the diagnosis is the replacement of the throttle position sensor (due to the fact that it has been mentioned in the definition of the error code). It is advised to avoid this common mistake while diagnosing every other trouble code.
