  • 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 P2128 indicates a problem with the throttle or pedal position sensor.

The diagnosis involves checking the wiring and connections of the sensor. The estimated repair time for this fault code is 1.0 hour.

The fixing cost is dependent on the hourly rate of the auto repair shop, which is typically between $75 and $150 per hour.

Other factors that may influence the cost include the location of the repair shop, the type of vehicle, and the severity of the problem.

The P2128 fault code is a common issue in automobiles. It is indicated by the engine light turning on or the service engine soon warning light. This code is related to the throttle pedal and can cause a lack of response when pressing down on the pedal.

When this fault code appears, it is important to take action immediately. Without a functioning throttle pedal, the vehicle may not be able to accelerate or maintain speed, which can be dangerous on the road. To fix this issue, it is recommended to take the vehicle to a professional mechanic who can diagnose and repair the problem.

Ignoring the P2128 fault code can lead to further damage to the vehicle and potentially cause a safety hazard.

What are the possible causes of the P2128 automobile fault code?

The P2128 fault code in automobiles can be caused by a faulty Accelerator Pedal Position Sensor, an open or shorted harness, poor electrical connection in the circuit, or a faulty Engine Control Module (ECM). To fix this issue, one 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 related wiring harness and connectors to fix the P2128 fault code?

To fix the P2128 fault code, start by checking the possible causes listed above. Then, visually inspect the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins. This will help identify any issues with the Accelerator Pedal Position Sensor harness or circuit poor electrical connection, which could be causing the fault code.

Is a faulty Engine Control Module (ECM) a common cause of the P2128 fault code?

While a faulty Engine Control Module (ECM) is listed as a possible cause of the P2128 fault code, it is not a common cause. The most common cause of this code is a faulty Accelerator Pedal Position Sensor or issues with its wiring and connections. To fix the issue, it is recommended to visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.
