[SOLVED] Fixing P2122: Low Circuit In Throttle/Pedal Position Sensor/Switch

If you’re experiencing a lack of response from your throttle pedal and your engine light is on, it could be due to the P2122 fault code. This code indicates a problem with the Accelerator Pedal Position (APP) Sensor or its circuitry.

The cause could be a faulty sensor, an open or shorted harness, or a poor electrical connection. It’s important to address this issue promptly as it can affect your vehicle’s performance and fuel efficiency.

The repair time for this issue is estimated at 1.0, and it’s recommended to visually inspect the wiring harness and connectors for any damage or corrosion.

To interpret the fault code, you can use an OBD-II scanner or take your vehicle to a mechanic.

If you’re experiencing an illuminated engine light and unresponsive throttle pedal, read on to learn more about the symptoms of the p2122 automobile fault code.

  • The automobile fault code P2122 has two main symptoms.
  • The first symptom is that the engine light turns on.
  • The second symptom is that there is no response from the throttle pedal.
  • These symptoms are important to note as they can indicate a problem with the throttle position sensor or the wiring associated with it.
  • It is important to address this issue as soon as possible to prevent further damage to the vehicle.

The automobile fault code P2122 can be caused by a faulty APP sensor, open or shorted harness, poor electrical connection, or a faulty PCM.

  • The automobile fault code P2122 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 P2122 fault code.

To fix the p2122 automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p2122, 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 automobile fault code P2122 indicates a problem with the throttle or pedal position sensor.

The estimated repair time for this issue is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour. Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop.

The P2122 code refers to a problem with the ThrottlePedal Position SensorSwitch ‘D’ Circuit.

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, which is the input to the torque based strategy. The P2122 code indicates that the ThrottlePedal Position SensorSwitch ‘D’ Circuit is low, meaning there is likely an issue with the sensor or its wiring.

What are the possible causes of the P2122 fault code in an automobile?

If you’re experiencing the P2122 fault code in your automobile, you may notice that the engine light is on and there’s no throttle pedal response. This could be due to 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 this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the wiring harness and connectors related to the P2122 fault code?

If you’re experiencing an engine light or service engine soon warning light, along with no throttle pedal response, it could be due to a faulty Accelerator Pedal Position (APP) Sensor or a poor electrical connection. To fix this, check the possible causes listed above and visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.

What are the symptoms of the P2122 fault code in an automobile?

If you see the Engine Light ON or Service Engine Soon Warning Light and there is no throttle pedal response, it could be due to the P2122 fault code. This code is 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 this issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or corroded connector pins.
