Are you wondering what the automobile fault code P1125 means? Well, when you see the Engine Light ON or the Service Engine Soon Warning Light, it’s a clear indication that something is not right.

In this case, the P1125 code points to a faulty Accelerator Pedal Position Sensor. It could be due to an open or shorted harness, or a poor electrical connection in the sensor circuit.

To fix this issue, start by visually inspecting the wiring harness and connectors.

Look out for any damaged components or broken, bent, pushed out, or corroded pins in the connectors. This repair is of moderate importance and difficulty, and it should take around 1.0 hour to complete. So, don’t delay in addressing this problem and get your vehicle back on track.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p1125 fault code.

  • The symptoms of the automobile fault code p1125 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p1125 can be caused by a faulty accelerator pedal position sensor, an open or shorted sensor harness, or a poor electrical connection in the sensor circuit.

  • The fault code P1125 can be caused by: a faulty Accelerator Pedal Position Sensor, an open or shorted harness for the Accelerator Pedal Position Sensor, and a poor electrical connection in the circuit of the Accelerator Pedal Position Sensor.

To fix the p1125 fault code, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p1125, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors for any damage.
  • Look for broken, bent, pushed out, or corroded pins in the connectors.
  • This fix should take approximately 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p1125 are the estimated repair time of 1.0 hour and the typical auto repair shop charges of $75 to $150 per hour.

The P1125 fault code refers to a problem with the Throttle Position Sensor (TPS) in your automobile. The TPS is made up of two potentiometer type sensors, known as the Accelerator Pedal Position (APP) sensor 1 and APP sensor 2. These sensors have circuits for a 5-volt reference, a low reference, and a signal.

The control module supplies the APP sensors with a 5-volt reference and a low reference. The sensors then provide the control module with signal voltages that are proportional to the movement of the accelerator pedal.

The signal voltage of APP sensor 1 is low when the pedal is at rest and increases as the pedal is depressed.

Similarly, the signal voltage of APP sensor 2 is low at rest and increases with pedal movement. When the control module detects that the signal circuits of APP sensor 1 and APP sensor 2 are not in correlation with each other, it triggers the P1125 fault code. This means there is an intermittent issue with the Throttle Position Sensor. It is important to address this issue promptly to ensure proper functioning of the throttle system in your vehicle.

What are the possible causes of fault code P1125 and how can I visually inspect them?

If you’re seeing the engine light or service engine soon warning light and have fault code P1125, it could be due to a faulty accelerator pedal position sensor, an open or shorted sensor harness, or a poor electrical connection in the sensor circuit. To visually inspect these possible causes, check the wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded pins in the connectors. This will help you identify and fix the issue.

How does a faulty Accelerator Pedal Position Sensor contribute to the engine light being on?

When the engine light is on, it could be due to a faulty Accelerator Pedal Position Sensor. This can happen if the sensor’s harness is open or shorted, or if there is a poor electrical connection in the sensor circuit. To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or broken pins. It’s important to address these possible causes to resolve the problem.

What steps can I take to fix fault code P1125 and ensure a proper electrical connection?

To fix fault code P1125 and ensure a proper electrical connection, start by checking the possible causes mentioned above. Take a close look at the wiring harness and connectors, visually inspecting for any damage. Pay attention to broken, bent, pushed out, or corroded pins in the connectors. By addressing these issues, you can resolve the fault code and establish a reliable electrical connection.

p1125 error fault code explained

If your engine light is on and you’re getting the P1125 fault code, it’s likely due to a faulty accelerator pedal position sensor or issues with the sensor’s wiring. To fix it, visually inspect the wiring harness and connectors, checking for any damage or corrosion.

Look out for broken or bent pins as well.
