The automobile fault code P1123 indicates a problem with the Throttle Position Sensor (TPS). The most common symptom is the Engine Light being ON or the Service Engine Soon Warning Light. The cause of this fault code can be a faulty TPS, an open or shorted TPS harness, a poor electrical connection in the TPS circuit, or a faulty Powertrain Control Module (PCM).

To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion. Additionally, look for any broken, bent, pushed out, or corroded pins in the connectors.

The repair time for this issue is estimated to be around 1.0 hour. It is important to address this fault code promptly to ensure proper functioning of the throttle system.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p1123 fault code.

  • The symptoms of the automobile fault code P1123 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p1123 can be caused by a faulty Throttle Position Sensor, open or shorted sensor harness, poor electrical connection in the sensor circuit, or a faulty Powertrain Control Module (PCM).

  • The fault code P1123 can be caused by a faulty Throttle Position Sensor.
  • It can also be caused by an open or shorted Throttle Position Sensor harness.
  • Another possible cause is a poor electrical connection in the Throttle Position Sensor circuit.
  • Lastly, a faulty Powertrain Control Module (PCM) can also trigger the P1123 fault code.

To resolve the p1123 fault code, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p1123, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
  • This fix is estimated to take approximately 1.0 hour.

The automobile fault code P1123 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of the repair will depend on the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

The P1123 fault code is related to the Throttle Position Sensor (TPS) circuit in the automobile’s Powertrain Control Module (PCM). The PCM constantly monitors the TPS to ensure it is functioning properly. When the PCM detects an intermittent high voltage in the TPS circuit, it sets the P1123 Diagnostic Trouble Code (DTC).

This code indicates that there is a problem with the TPS circuit, specifically with the voltage being intermittently too high. It is important to address this issue promptly to ensure the proper functioning of the throttle system in the vehicle.

What are the symptoms of the automobile fault code P1123?

If you see the engine light or service engine soon warning light on, it could be a sign of trouble. The fault code P1123 is often caused by a faulty throttle position sensor or issues with the throttle position sensor harness. It could also be due to a poor electrical connection in the throttle position sensor circuit or a faulty powertrain control module. To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion. Additionally, look out for broken, bent, pushed out, or corroded connector pins.

What are the possible causes of the P1123 fault code?

If you’re seeing the P1123 fault code with the engine light on, it could be due to a faulty throttle position sensor, an open or shorted throttle position sensor harness, a poor electrical connection in the throttle position sensor circuit, or a faulty powertrain control module (PCM). To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. Don’t forget to address the possible causes mentioned above.

How can the P1123 fault code be fixed?
