The P2124 fault code in automobiles refers to a problem with the Accelerator Pedal Position (APP) Sensor. The most common symptom is the Engine Light turning on. The cause of this issue could be a faulty APP sensor, an open or shorted APP sensor harness, a poor electrical connection in the APP sensor circuit, or a faulty Powertrain Control Module (PCM).

The importance of repairing this issue lies in the fact that it affects the vehicle’s acceleration and performance.

The repair difficulty is moderate, with a repair time of 1.0. To fix the issue, one must visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2124 fault code.

Here are the symptoms to look out for:

  • The P2124 fault code in an automobile can cause several symptoms.
  • These include the engine light turning on or the service engine soon warning light appearing.
  • The vehicle may also experience a decrease in power or acceleration.
  • The throttle may become unresponsive or have delayed response times.
  • The engine may also stall or have difficulty starting.
  • Additionally, the vehicle may experience poor fuel economy and emit higher levels of emissions.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code P2124 can be caused by a faulty APP sensor, open or shorted harness, poor electrical connection, or a faulty PCM.

  • The automobile fault code P2124 can be caused by a faulty Accelerator Pedal Position (APP) Sensor.
  • It can also be caused by an open or shorted Accelerator Pedal Position (APP) Sensor harness.
  • Another cause can be a poor electrical connection in the Accelerator Pedal Position (APP) Sensor circuit.
  • Lastly, a faulty Powertrain Control Module (PCM) can also cause the P2124 fault code.

Listed below are possible fixes for the automobile fault code p2124, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p2124, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The fault code P2124 indicates a problem with the throttle or pedal position sensor. The diagnosis involves checking the wiring and connections, as well as testing the sensor’s output. The estimated repair time for this issue is 1.0 hour.

The cost of fixing this fault code can vary depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour. Therefore, the total cost of fixing the P2124 fault code can range from $75 to $150.

The P2124 code refers to the ThrottlePedal Position SensorSwitch ‘D’ Circuit Intermittent. The Accelerator Pedal Position (APP) sensor is an input to the Powertrain Control Module (PCM) and used to determine the amount of torque requested by the operator.

There are 2 pedal position signals in the sensor, APP and APP2, which have a positive slope but are offset and increase at different rates.

If a concern is present with one of the circuits, the other input is used. The pedal position signal is converted to pedal travel degrees by the PCM. The P2124 code indicates an intermittent issue with the circuit for ThrottlePedal Position SensorSwitch ‘D’.

What are the possible causes of the P2124 fault code?

If you’re experiencing the P2124 fault code, you may notice that your engine light is on. This code is typically caused by a faulty Accelerator Pedal Position (APP) Sensor, an open or shorted APP Sensor harness, a poor electrical connection in the APP Sensor circuit, or a faulty Powertrain Control Module (PCM). To fix the issue, it’s important to visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors related to the P2124 fault code?

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to the P2124 fault code, you may need to visually inspect the wiring harness and connectors related to the issue. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This could be caused by a faulty Accelerator Pedal Position (APP) Sensor, an open or shorted APP Sensor harness, a poor electrical connection in the APP Sensor circuit, or a faulty Powertrain Control Module (PCM).

What are the symptoms of a faulty Accelerator Pedal Position (APP) Sensor that triggers the P2124 fault code?

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a symptom of a faulty Accelerator Pedal Position (APP) Sensor that triggers the P2124 fault code. The cause could be a faulty APP Sensor, open or shorted APP Sensor harness, poor electrical connection in the APP Sensor circuit, or a faulty Powertrain Control Module (PCM). To fix the issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or broken, bent, pushed out, or corroded connector’s pins.

p2124 error fault code explained

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to a faulty Accelerator Pedal Position (APP) Sensor, APP Sensor harness being open or shorted, APP Sensor circuit poor electrical connection, or a faulty Powertrain Control Module (PCM).

Check the possible causes, visually inspect the related wiring harness and connectors, and look for damaged components or corroded connector’s pins.
