The P1271 fault code refers to a problem with the Accelerator Pedal Position (APP) Sensor 1-2 correlation.

This code indicates that there is an issue with the relationship between the two APP sensors within the Throttle Actuator Control (TAC) module assembly.

The TAC module assembly, which houses the APP sensors, is mounted to the accelerator pedal bracket. There are three individual APP sensors within the TAC module, each with its own signal, low reference, and 5-volt reference circuits.

These circuits work together to determine the position of the accelerator pedal.

When the accelerator pedal is depressed, the signal voltages from the APP sensors increase. However, in the case of a P1271 fault code, there is a discrepancy or lack of correlation between the signals from Sensor 1 and Sensor 2. This can lead to issues with the throttle control system and may result in reduced engine performance.

If you encounter a P1271 fault code, it is important to have the accelerator pedal position sensors and their circuits inspected and tested. A qualified technician will be able to diagnose the exact cause of the correlation issue and recommend the necessary repairs or replacements. Ignoring this fault code can lead to further damage to the throttle control system and potentially unsafe driving conditions.

What are the possible causes of fault code P1271 and how can I visually inspect them?

If you’re seeing the engine light or service engine soon warning light and have fault code P1271, it could be due to a faulty accelerator pedal position (APP), an open or shorted accelerator pedal position harness, or a poor electrical connection in the accelerator pedal position circuit. To visually inspect these possible causes, check the related wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded connector pins. This inspection will help you identify any issues and take appropriate action to fix them.

How does a faulty Accelerator Pedal Position (APP) lead to the engine light being ON and what steps can I take to fix it?

If you notice that your engine light is ON or you see a Service Engine Soon Warning Light, it could be due to a faulty Accelerator Pedal Position (APP). This can happen if the Accelerator Pedal Position harness is open or shorted, or if there is a poor electrical connection in the Accelerator Pedal Position circuit. To fix this issue, you can 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.

What should I look for when inspecting the wiring harness and connectors related to the Accelerator Pedal Position circuit to resolve fault code P1271?

When dealing with fault code P1271 related to the Accelerator Pedal Position circuit, it’s important to inspect the wiring harness and connectors. Look out for any visual signs of damage, such as broken or bent pins, corrosion, or components that are pushed out. These issues can cause a poor electrical connection or an open or short circuit. By visually inspecting the wiring harness and connectors, you can identify and resolve any faults that may be triggering the engine light or service engine soon warning light.

p1271 error fault code explained

If your engine light is on and you’re getting the P1271 fault code, it could be due to a faulty accelerator pedal position (APP), an open or shorted accelerator pedal position harness, or a poor electrical connection in the accelerator pedal position circuit. To fix this, visually inspect the wiring harness and connectors, check for damaged components, and look for any broken, bent, pushed out, or corroded connector pins.
