P2124 - OBD Trouble Code
OBD Code P2124 - Throttle Position Sensor/Switch D Circuit High Intermittent
Error code P2124 flashing? Don’t know what to do about it? Well,
only for our customers Parts Avatar has listed here all that you need to know
about this error code. It is valid for all 1996-newer vehicles (Dodge,
Chrysler, Hyundai, Jeep, Mazda, etc.). This diagnostic trouble code (DTC) is a
generic powertrain code. Although the code is generic in nature, it's repairs
may vary according to the make/model of the vehicle. When the code is stored,
it indicates that the powertrain control module (PCM) has identified an
intermittent error in the circuit for the "D" throttle position
sensor (TPS) circuit.
Learn More About OBD Error Code P2124
In order to calculate the fuel delivery and ignition timing, the PCM utilizes the input voltage signals from the TPS. also, this input data from the TPS is used to regulate the intake air flow, exhaust oxygen content, exhaust gas recirculation (EGR) function and engine load percentage. When a certain number of intermittent or irregular signals are detected from the TPS over a period of time and under specific set of circumstances, the code P2124 is stored. The malfunction indicator lamp (MIL) illuminates too.
What causes this problem with the Throttle Position Sensor/Switch D Circuit High Intermittent?
- A damaged or wrongly adjusted TPS
- The TPS "D" wiring or connectors shorted or loose
- Binding or damaged throttle plate
- A defective PCM or a PCM programming defect
Replace/Repair These Parts To Fix Code P2124
- Throttle Position Sensor - It is notable that the
signals from the throttle position sensor measures and combines many times per
second with other data such as air temperature, engine RPM, air mass flow, and
decides how quickly the throttle position has to change. So we advise you to
change your malfunctioning throttle position sensor as soon as possible in
order to get rid of a whole lot of problems as well as the error code P2124.
- Switch Circuit - A distorted switch
circuit accompanies along a lot of problems related to the functioning of the
vehicle, overheating of the switch and also illuminates the check engine light.

- Intake Manifold Tuning Valve - A lot of issues arise
like a no start condition, sluggish engine cranks and constant vehicle stalls
when the intake manifold tuning valve is faulty. Tune into Parts Avatar for you
new intake manifold tuning valve offered at just the right prices.
- Powertrain Control Module - Error code P2124?
Stressed? But don’t know the reason behind all these problems? A damaged
powertrain control module leads to downward emissions along with 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.
- Accelerator Pedal Position Sensor - Having problems in the
accelerator pedal position sensor? This issue stimulates not only the error
code P2124 but also a number of problems like the vehicle's ability to
consistently accelerate or decelerate as instructed by the driver is reduced.
Repair or replace your APP sensor as soon as possible in order to avoid further
complications caused by the error code P2124.
- Engine Control Module - Facing the error
code P2124? An inferior quality ECM can always be hazardous for the system also
it is one of the primal causes behind the occurring of the error code P2124.

Easy Diagnosis of Engine Error OBD Code P2124
Here are some steps which you should follow in order to diagnose this fault code:
- Numerous instrumental tools should be employed to successfully diagnose this error code. A specialized OBD-II scanner (or code reader), a digital volt/ohmmeter, and a oscilloscope should be used along with a manufacturer’s service manual
- Firstly, start with a visual inspection of the wirings, electrical components and connectors. All the corroded or disconnected ones should be changed as per the requirements
- Now that the repairs have been performed, we advise you to retest the system to ensure success. Well, if all wirings, components and connectors (including fuses) appear to be in normal working order, the scanner (or code reader) should be connected to the diagnostic connector to record all the stored codes and freeze frame data
- It is advised to register the information, as it is essential while diagnosing intermittent conditions (that might have contributed)
- Again, the vehicle should be reset and test driven to see the results. This will be helpful in determining if or not the error is intermittent
- The vehicle should be test driven to see if the code returns
- If the code fails to reappear, an intermittent condition should be blamed for triggering the code
- Also, it should be noted that intermittent conditions at times prove to be quite challenging to diagnose. Also, in many cases, it may have to be allowed to worsen before treatment
- This code strictly applies to the vehicles that have an electronically controlled throttle body installed
- This kind of system is often known as “drive by wire” throttle bodies
- The sensor installed on the accelerator pedal arm transmits a voltage signal to the PCM (or other related controllers) that order the throttle body opened or closed (based on the conditions)
- The PCM sends voltage signals that actuate the throttle actuator motor in the direction required by changing voltage levels and polarity
- Just when the throttle actuator motor turns, it turns along a gear in the throttle body that is intermeshed with a larger gear
- This sort of a variation enables the throttle plate to open quickly, slowly or gradually depending upon the controller’ order. Examine the throttle position sensor electrical connector too
- The connector should be disconnected from the sensor. A digital volt/ohmmeter should be used to check for any voltage and ground signals
Common Mistakes When Diagnosing the P2124 Code
Here we have listed only for you a few common mistakes that should be avoided:
- A failure in the accelerator pedal position (APP) assembly
- A malfunctioning powertrain control module (PCM)
- A defective throttle control motor
- Wiring problems in the system
